Good informative video, thank you. I wanted to mention that unfortunately the pricing for the motor and control module on some Trane units is so ridiculously over priced that some do it yourselfers will be forced with buying only the motor or only the control module. I’m talking about $390 for the motor, or $390 for the control module, $780 if you want to replace both at the same time. I don’t know how they get away with pricing parts this way, but somehow they do. Meanwhile, thanks again for posting a great video.

You are absolutely correct Nurfet Alic, thanks

Great video, thanks for the info. Do you have any idea what voltages or signals are required or are present on the connector between the hub and the hvac controls? I noticed there where only 5 conductors going into the potted circuit from the connector. That is a very bad location for electrolytic capacitors as heat is the number one killer for these very short lived devices. You would think they would have put the ESC (Electronic Speed Control) in a different location and just ran three wires to the motor. All about money I suppose..... Thanks again!

You make great videos. I have had the same blower motor for over 30 years at my house. The only problem with old equipment is finding a young tech smart enough to provide service, if you need service. Bad caps are primary in computers, televisions, etc. Guess where they are made? New tin-foil cabinet HVAC is standard these days, and actually not a new phenomenon. Again, I enjoy watching your videos. My comments are not a criticism of your work. Cheers

I'm new at service. I had one yesterday where it has the constant 220v and it had 24v on the other side. I knew if had be bad

How do you test the hub? I must have missed it? Thank you

FYI, i've had a couple of those UEI amp probes over the years. I really like them and cheaper than FLUKE. Here is a problem I discovered though. They have two strong magnets on back that will actually pull the negative spring battery contact away from the battery. The meter will malfunction, so always check your meter operation before using it? The solution for me was to remove the magnet on that battery side and still have the other when needed.

Hi i have a Trane XR series gas furnace with a ecm variable speed blower. The magnets seperated from the motor stator/shaft. I epoxy/glued the magnets back on. The motor now runs with out grinding but it seems its in low mode or just below low then the heater goes out on temp limit. It tries to ramp up to high speed but never spins high. It seems stuck in low mode or just shy of low mode. Any ideas? Replace the motor or do i replace the ecm part of thr motor? Thanks for posting i hope you can reply.

Hi I try to fix my ECM 2.3. I test the module of the motor and it seems ok with not burn out. I am trying to follow your explanation about checking the winding on the motor. So when I check my blue and red I get .008 . Then black and red .008 but the balck and blue is .004 on resitance. Also, I checked the continuity on all three of them and all of them beep. So that mean my motor is bad? Your help will be really appreciate. Thank you so much in advance

I would check your meter before checking the motor to make sure that you are at 0.0 ohms of resistance and your probes are not off. Most times it is the module that is bad but yes the motor is a three phase and should have the exact same resistance for each set of wires. Also a side note, most manufacturers charge almost the same for both compared to just the one unfortunately but the other thing to remember is that you need to purchase this from a distributor that handles the manufacturer of your equipment whether york, bryant or some other, thanks

What if blower motor is constantly running? Had ac man come over and he switched out the board on the outside that goes to thermostat and didn’t fix nothing so he says it has to be blower motor?!? Is that true or do I need to find someone else to look at the ac?

Good video! Due to the cost I see so many mechanics replacing them with standard motors and a new relay due to the customer not wanting to fork over the cash. Sad but real world.😎

You have to do what you have to do to get the customer running again. I will also add two concerns though.Techs will want to make sure that they are checking the refrigerant charge afterward to make sure it is the same airflow since you were not there before to measure the airflow.The other thing is you would only replace them with like horsepower blower motors on single speed units only and not on something like a two speed, three speed, or variable speed furnace since the board will be sending out low voltage signals to change airflow speeds.

Awsome video. I just bought my system and got the Variable Speed air handler and compressor. Lennox XC20. Everyone keeps telling me oh these systems are complex to install and stuff but to my knowledge the installation of air handler and condenser unit is the exact same as other single speed units. The only difference is the communication stuff and wiring for the thermostat which one can do if they understand. Don’t know why everyone keep saying it’s complex. Do you know of any other differences?

I have a ecm 2.3 motor that I need to replace. I can't find the same exact model but I can find them with everything exactly the same except for rpm. can I use a slightly higher or lower rpm motor?

Have you ever come across an ECM motor that sounds like a jet engine winding up? Sounds normal at low speeds. From 2007 ECM Goodman Furnace 97 efficient. Was working fine then changed recently. No ductwork and air flow issues. GE ECM Motors ECM 2.3 DG03 Controller. ROT CCW Amp 9.6/6.8 RPM 1050 Blower Motor. Controller causing this noise or motor itself? Could it be the main board sending voltage to the controller?

how can you distinguish between a variable speed motor and a psc motor by just looking inside the furnace? can you tell by serial/model#? thanks.

Variable speed has plug locations, x13 have spade terminals and psc has a capacitor, thanks Mark!

That "three-phase motor" has a hellish number of poles....depends how they are wired I guess. Just saying. Question. When would motor speed be controlled, say at lower than synchronous (full speed)? Versus letting it run at full speed? On a residential AC system, the compressor/condensing/evap components start when the t-stat calls for cooling. What and how is the variability of blower speed determined? I'm a electrical controls guy retiring into my first love (and prior educational pursuit), HVAC. Thanks to all for any feedback (there I go again).

Is this also called the variable speed module? I misdiagnosed one on a Lennox G61 the other day. Could I have used my techmate pro

@acservicetechchannel

Yes the tecmate would help the diagnosis. If the tecmate turns the motor on and there is not a fluctuation up and down and up and down again in speed then the motor is good, thanks

Thats just it. If you use the genteq tool to tell if the variable speed motor is bad then you just have to find out if it is the hub or the actual windings in the motor. If the windings are good then it is the hub that is bad. We can't test the hub disconnected and off. It is a process of elimination just like verifying if a control board is bad, thanks Luis!

About $385 for ecm and around $800 for whole unit for my 1/2hp 2.3. I was going to try to switch to PSC which wasn’t going to work then evergreen em x-13 set to single speed per servicer. I ended up buying a refurb of my motor plus ecm from a shop in Tampa! FL $299.99 total including next day ups. Today I installed and started right up. My multimeter battery connector broke a while ago and didn’t have time to fix so bought a nice clamp meter as can always also use a clamp and have a smaller meter to bring around. Tech didn’t bother trying to diagnose more than 240 at plug to ECM so need to replace whole unit (quite a lot over $1000). - Turns out motor is fine on old. I don’t visibly see any thermister or capacitor damage in ecm so at some point I’ll check that. Would be nice if there was a law requiring them ecm or motor to be diagnosed and further if it’s a $2-$10 part to fix it rather than force people to pay for this nonsense and generate waste. What happens to old - it’s not in warranty so it gets scrapped. Yay that makes sense.

You can't replace this with a psc for a multispeed furnace but for a single speed ac unit, you can replace it as long as the cfm is the same. You would need to make sure the transformer can support another load and add a contactor or fan relay to the low voltage to control the fan when calling for the blower to come on, thanks

my fan wont start up and make air come out of vents...I assumed it was a capacitor but the hvac guy claims I need a new motor assembly. Once I can get the fan running I can leave it on all day with no problem so I'm going up on my ladder tomorrow to take a look for myself.

I'm thinking it should be off when just the blue & white wire are hot and need orange or red wire to get hot to engage, because when heater engages it sends 0.035v thru orange and red wires. Would that mean the bell housing has a short causing it to run even when thermostat is turned off? Wow i just read my manual L&N are supposed to be hot all the time with low voltage C & 1-5 turning it on so i must have bad bell housing.

If the blower motor runs all the time, there may be a few things. It may be an open limit. First check for 24v from w to c on the board when you should not have it meaning the tstat off and then check for 24v going through your limit switches,. If a limit is open the blower won't shut off, If you have 24v from w to c when not calling at the tstat then bad tstat or bad wires. Try taking the tstat face off and see if the blower still runs, thanks look up acservicetech blower fan motor won't shut off video

Grandpa stood on the curb said big house big furnace small house small furnace. Back then they only made 3 sizes. Now with several options heat calcs make huge difference sold many jobs with smaller furnaces than competition offered because of taking time to measure for heat calcs & guarantee it would work to large cold swings to small can't keep up, cost more to operate. Measure walls windows doors find what insulation in wall & attic windows single Payne double payn. how much below frost line basement walls are everything above frostline calc at 15 below depending on your area. Im in wisconsin some places calc at 9 below farther south you go higher that number. Every thing below frost line is a constant. 50 degrees including floor remembering Heat flows to cold. Warm air rises. there are sheets like lennox has good ones now there are computer calcs that are easy every manufacturer has one depending on what brand you sell all are good with AC figure 2 people per bedroom. Sold many jobs by doing calcs when no one else did. Only had one problem with a hydronic cast iron baseboard that I still do not know how to calc. But its amazing to do calculation replace 80 k with 40k & gauratee it will work to 15 below when competition quotes 80 k. And your right because you took the time to see what they actually needed. Good luck doing what is best for your customer makes you money doing for them what you would do for yourself & believing in your self & your product brings more referrals than any advertising.heat calculation not that hard competition thinks they can copy rating plate sell existing size not taking in customer or previous owner may have insulated replaced windows or added addition to structure. Spend time with customer sell quality don't compete with low bidder. Selling 2 stage variable against 92% 96% not much of a pay off but 2 stage variable uses 79 to 250 watts against single 92% that uses 750 to 1000 watts. Educate your customer. Don't try to sell price your worth more than your competition charge for that if your sincere they will pay more for you to take care of their needs. Take time with them explain optional equipment UV purifier, air cleaner, humidifiers, cover everthing then slide your quote to them & shut up he who speaks first loses. If husband and wife make a excuse to get something from truck let them talk. You come back in they buy from you. Because you took the time to explain & do it right. Even if you are $500 higher than competition they will see the value in you. Sincerity & references sells better than any hype or bullshitter that tries to sell by cutting price.

If the motor check out and you have an x14 without a harness, would the check procedure below verify if you have a bad bell/module? First, confirm line voltage on the motor at terminals L and N on the motor connector. Next, confirm the C terminal on the motor by checking for 24 volt ac from that C terminal to the R terminal (or R wire, usually red) on your low voltage terminal strip. Then connect alligator clips to R then one at a time connect the other end to terminals 1 thru 5 on the motor. The motor should start up and run on each of those speed taps. If you have a situation that your motor quits after one minute in some circumstances, you should test run each speed for an extended period of time (5 minutes ought to be ok). Finally, use an amp meter to check the amp draw of the motor to ensure it's not over-amping.

The efficiency overall when including the watts from the motor is not going to be as efficient as the x13 because you are still working with psc windings. I usually replace the X13 with either a standard psc if I can't get the motor fast enough or the X13. Thank you for the thoughts!

I thought O.L meant open line?

Why would ECM motor that worked for 3 years start running backwards how do you reverse it

I think it has to be replaced. Nobody has the tool to reprogram it.

Those three wires are low speed medium speed and high speed. That whole back in can be replace with a capacitor and a 12 volt relay That is a 3 speed motor not a 3 phase motor. Just you would like to know. Have a good one!

Hey Walter, that is a three phase motor. Each pair of windings have the same ohm reading. Multi speed motors have different resistance values on each speed. The highest ohms are low speed and lowest ohms are high speed, thanks

My module is $230, or $580 for motor and module together. That's a bit more than $50-100.

Multiple suppliers of mine charge 50-100 more for both compared to just the module. That is great then that it is that much cheaper if the module is all you need. Just make sure that you are purchasing this from a distributor that has purchased this from the manufacturer of your equipment which has programmed this for your model number unit, thanks for letting me know Kris!

i have the same experience. Its normally about $80 difference between purchasing the motor or just the bell housing. its not worth it. might as well get the whole assembly. less headache and potential for future problems.

That burned out part is a capacitor.

I would just replace the whole thing :D

Both capacitors look bad. Bad capacitors will also cause other components to fail such as MOSFETs.

That unit has 2 bulged caps. Could replace those for abt $2 each before you pay $600 for a motor.

@@leomcadams1751 Cut the leads from the top and solder the new part to the exposed leads.

The prices HVAC manufactures are charging for the ECM controllers is absolute highway robbery... American consumers are getting screwed so bad it's unreal... and now they're even potting the circuitry to make sure you can't do a component level repair. The capacitor that failed on that unit could probably be purchased for less than $5... but since it's potted you have to throw the whole thing out and buy a new one for $500. This form of "marketing" should be illegal! My next furnace, I'm going to avoid ECM motors like the plague... the control modules fail FAR too much. I think more often than not, people spend more on replacement of these fault prone motors than they save in electricity.

That’s what the companies want. They want you to dispose of bad products they build to fail in a short period of time, not repair the product so you can buy a new one for a ridiculous amount of money.

I am in the process at this moment of trying to figure a practical way to replace the thermistor in an EON module that is potted. It will not be possible to do it at the pcboard level. I'm thinking that I should break the thermistor apart and attach a new one to the leads of the old thermistor that remain above the potted surface. My dilemma is that this TRANE unit is still under the factory warranty and, should they examine this part after it is returned to them, they will take it out on me. I wonder if they even bother to look of just scrap them. They have left me high and dry because TRANE has decided that the motor/module should be replaced as a "unit." Nonsense, the motor is fine! It's 95 deg and 90% humidity here now and TRANE has NO inventory nationwide to ship to my authorized dealer for ONE MONTH!!! I'm an EE, have diagnosed the problem and know what I am doing. I can fix this in a NY minute but risk losing the balance of a 10 year P&L warranty (3 more years). Honestly, there needs to be class action litigation. I realize that, ultimately, it's the government's fault for forcing these efficiency standards, all in the name of GREEN, but what's a landfill full of these damn things doing to the environment???

@@georgemcmanus6073 Agreed - it is freaking ridiculous! I replaced the thermister in my ECM when it went out but it was not potted. The "logic" of this situation is completely incoherent. They put this thermister in the design to protect the rest of the circuity from damage at start up... but when it fails from all the stress it takes, they say throw the whole ECM AND THE MOTOR away! Over a $5 part. I would just solder a new one on to the leads - they are so intent on treating the entire motor as a unit that I doubt they'd ever know if something else failed on the motor. If its still under warrantly though - then aren't parts like the motor covered? Are you just trying avoid labor cost to reinstall the motor?

@@rhymereason3449 No, I'm covered parts and labor 100% until 2027. The problem was that they said TRANE did not have the assembly and it was estimated to be in-stock early August! Well, it's hot and humid as hell here and that is unacceptable. That started the hunt for a resolution to the issue and how I discovered all of the craziness involved with the ECM motors. Bring back PSC motors. Wait, that's right, the government says no more furnaces are to have PSC motors. And now, this week, PFC's are again being regulated by the EPA so that you can pay through the nose for refrigerant in the near future.
