Dammm I did a service call and the motor kept spinning even tho the ts was off, now I know why thanks boss couldn’t help that day 🤨

I bought a Genteq 5SBA39FLP8013 ECM blower motor to replace the Broad Ocean motor which stopped working in my air handler. The Genteq is an X13 with 5 speed taps as shown in the video. I decided to test it before going to the trouble of mounting it in the air handler. I laid it on its side next to the air handler and connected the wiring. The thermostat was set to fan only. When I turned on the power the shaft began to spin for about 1 second and shut off and then a few seconds later it came back on and shut off and continued this pattern until the power was shut off. My neighbor's son in law is a HVAC technician, so I called him and explained the problem. He told me that the motor detects the load that is on it and adjusts for that load to maintain a steady speed. It needs to have the blower wheel on it and be mounted in the blower housing in order to detect a load. I installed it in the air handler and it works perfectly. I don't know why this information is not in the video and why the motor in the video is not showing this problem.

HELLYA! Paid $85 for a service call for the guy to lie to me about the issue. Watched AC Service Tech video, got the skinny, back up in the attic troubleshoot to a likely blown Cap on the ECM module, order an exact replacement off Ebay for $82. 3 hours of YT videos, 1 hour to Trane shop to be denied, 1 hour surfing Ebay, then 10 minutes mounting replacement ECM and I'm UP AND RUNNING! It was a total of 6 screws to fix!! You saved me $2400!!!!!!!!!!!!!!!!!!!!!!!! Signed up for Patreon. I'm not an HVAC pro so would have preferred a one-time payment.

Your machine could have been out off warranty. You were paying parts and labor. Did you know it was the blower motor BEFORE he got there? I'm glad you fixed it. But don't bash the tech.

@@hliz8818Company, Tech or both, they tried to get $2500 for the blower replacement or better yet a $8000 full system replacement. It's a year later and I'm out $75 in parts and my HVAC is running great. I spent more time watching this video than the repair took. If that's how you "just do our part" you might want to think about how you sleep at night.

I LOVE KZread!!!!! The motor on my furnace went out. An AC/Heat company said it would cost over two thousand bucks to fix it, due to the type of motor ECM. which cost around 1500.00 dollars. So like always I went to youtube to see how hard would it be to replace the motor. To my surprise, there were many videos showing how to do it. Looked pretty simple to me. I found a place that sells rebuilt motors and found exactly what I needed for $300 dollars no tax or delivery charges. Just got the motors and fixed my unit in less than two hours, most of that time was cleaning the furnace. The wife is happy and I am very happy. Thank you, KZread you're the best!!!

What site was it?

Unbelievably helpful, THANK YOU!!! I literally got 2 quotes - one was for $3,850 to replace motor and ECM and the other company said there was not available replacement available and said I absolutely MUST buy new unit which was $10-12k. I just replaced the motor and ECM with parts from Supply House for $750. However, from your video I figured out that it was the inrush current limiter that had blown and bought new component for $5.07, so will either save as backup or sell used but working on eBay and probably get $200-300 of my money back, I would have sure paid it.

I got myself into the trade watching KZread. AC service tech knows their stuff. I started at an apartment complex as a groundskeeper and within two years I was lead tech. Now, I’m in residential working for a really good company that really doesn’t have time to train. Most companies don’t have the resources (especially in todays economy with everything getting so expensive), to send two techs to a house so one can learn. So you either start as a helper making $10/hour where you’ll be on install or you learn the stuff and go in making $30/hour on service. Learn this stuff. You won’t be rich but you’ll make a comfortable living. I’ll be moving into industrial and commercial soon. We do commercial now but I’m looking forward to working on more complicated things like chillers and oil heaters.

Thank you so much for the information on this ECM. I'm a maintenance technician at a retired community and I have ran into some problems with some of my air handler blower with this ecm. So watching this video gives me a little more information on what to look for. Again thank you for your fine work & information!

Excellent vid. IT would be nice to know what application of the 24 VAC motor speed control signal actually do, and how one goes about "programming" which speeds are active. It is clear from your vid that only 1 control signal is to be applied at a time. What if the air handler controller feeds 2 at a time?

I found the same thing… a Goodman system feeds 24v to 1&2 when heating or cooling and 24v to just 1 with call for “G” alone…

I live in the Chicago area, lots of supply houses, but on a Saturday night at 100 bucks + an hour the bill can be ridiculous. I've also had supply houses be out of stuck. I always carry a standard PCM motor for older style motors. At -10 outside the people don't want to hear you'll be back tomorrow if you can find the part. So, I will install the PCM motor and hot wire it low for heat and high for AC.to give them service. I know some guys that carry an old working motor just to give service and you can take your time getting the right part. I carry a 1/2 hp. does 1/6 thro 1/2 and 90% of my calls.

Ac company came to fix our unit thought it was the blower assembly, then the board find out the yellow wire to the thermastat had voltage on it all the time. Swapped with another extra wire in the harness everything is good.

I have a carrier unit with the broad ocean ecm you have in the video. I have had an issue 3 times now where all of a sudden when the ac turns on the inducer/blower motor doesnt turn on. The first time I got it working, but to be honest not sure what I did is all I did was test just like you said and when I hooked back up it worked like nothing had ever happened. It then did it again several months later. I was out of town but the wife and kids were at home and I just called an hvac tech to come and look at it since I couldn't trouble shoot. I had the wife simply kill power to the whole unit and when the tech got their the next day he flipped the power back on and it worked with no issues. Basically paid him for a trip to come to my house and turn it on. Well now it has been about 6 months since hat time and it has done it again. Of course I am out of town, but I will trouble shoot when I get back. Sorry for being such long winded but wanted to give you as much info as possible. So you have any idea why it would be intermittently not working. Why would it not work then when turned off for a period of time or when testing it it just all of a sudden works like normal again. I had thought the first times were due to power surges and actually installed a whole house Honeywell surge protector about 3 weeks ago so it wouldn't happen again. This last time, today my wife said there were not any power surges. Any help would be appreciated.

You may have an intermittent problem with that blower motor. That means it’ll work when it wants to and it won’t work when it wants to. That’s a sign of a bad module or blower motor or both.

Thank you! You're a saint for bringing this secret information to the people! And to clearly explained. The manufacturers and installer/dealers are in cahoots to make it hard for the owners of the appliances to handle their own hardware failures. I don't much like situations where early failures bring profit to someone else, after I shelled out for the equipment. I'm not saying everyone should try this at home, but if you are technically educated, it's nice to have the simple facts so you can take care of issues.

You always do great training videos, but this one is one of my favorites. Unfortunately I have already ran across a OEM replacement motor that was programmed wrong, not for sure if it was the manufacturer or the distributor (lot of distributors are able to program motor with OEM specs). Since the motor was under warranty, the service call was negative profit for labor.

Great video on ECM's, I hope you put out more video's on Broad Ocean and Rescue motors (maybe you did already??). I would change your explanation on the motor potentially overheating if there's an airflow restriction because motors draw less current with an obstruction (less work as your not pushing as much air - less work = less amperes). I subscribed, looking forward to watching more technical videos!

My ECM had magnets detached from the rotor. Cleaned off the junk glue film remaining on the rotor and magnets, and re-affixed them with epoxy, original orientation, spacing. Motor working fine again. Thank GE, Beloit and Junktek or whoever owns this now Genteq for stupid glue application. Even multirotors have the magnets arranges so they cannot be thrown off.

Great information Greg! Just to add another tidbit of information, I had purchased a generic X13 preprogrammed ECM motor, but the motor ran backwards. There are three stator windings which are very similar to a 3-phase motor. One can cut any two of the three wires on the connector going to the stator windings, reverse the leads and the motor will run in the reverse condition. I don't recommend this, but it will work as I've done it to get a unit to work. Fortunately, the motor speed was very close to the original.

Some of those motors have a way to program it to reverse the direction of the motor. Also, the motor is a three phase motor, but that doesn't mean you can hook it up to three phase straight from the breaker panel as a temporary work around. I tried this as a last ditch effort to get the AC blowing again, and the windings started to cook. We were over 80 miles offshore so getting a replacement wasn't going to be quick. Thankfully, the field had a crew boat that was making a run to the beach for resupply the next day.

Great video! Too bad most control modules are potted. I do component level repairs on just about everything, so it bothers me when manufactures make things disposable. I liked that you said that the MOV is replaceable. Hopefully some technicians will have good soldering skills and will replace them rather than swapping out the module and/or motor. I have worked on some large 3 phase VFD drives for big commercial air handlers, and most of the time its poor soldering and capacitors. The VFDs that I work on are external, and are not potted. Of course there are no schematics, so it is sometimes a challenge. Keep up the great work. Your book is great - I purchased it about a year or so ago. Thank You.

Your video is friggin awesome! I have been dealing with problem #2 (the pulsing up and down of the speed of my GE 2.3 ECM 3/4 HP MOTOR 5SME39SL0674 for the last 14 months. In your video you explain that IF the motor is still in the squirrel cage that it might act different than in your video. I'm listening to my a/c run right now as I type. When it comes on initially it comes on soft and then slowly ramps up to full power, then suddenly drops down low to almost as if it was OFF but it is still blowing air out of the vent if you put your hand up there to test...then ramps up to full power again. Up and down about 3 to 5 times per cooling cycle (about 5 to 10 minutes typically). Does that sound about right for it possibly being the ECM module on the back of the motor? I have already replaced the main system control board AND replaced the actual blower motor with the exact same results still. Thanks again for posting. I feel confident that you have isolated my problem with this video already.

I love you man . You are the best .

I’m about to graduate from HVAC course but my IBM went out and the tech that came out did a resistance test on the module and he said it was at 18 ohms but normal limits should be between 10 and 20 so he said it was starting to fail. He replaced the whole blower with a new one that didn’t come with a module on it. So I’m the future I can check the resistance of the motor itself without dealing with the module although the module is cheaper to replace than a motor.

Thank you sir.

What voltages do you expect to get out of the module and is there a way to connect power to the motor for temporary without the module? Maybe some type of universal module you can pop in there until you get the new part?

Good explanation,thx,what would be the case if the motor cycle off and on,this will be the module or the motor,thx

First of all your videos are great. I don’t usually subscribe but I felt compelled to do so after watching two of your videos. What is the expected resistance 1/2 Hp 208/230V X13 motor. I’m getting 12.9 ohms on all. Sorry I’m sure you already answered in comments here or elsewhere but I don’t see how to search comments.

Can you pls do a video on two-stage compressor (working/troubleshooting)

Thanx

My motor struggles to get going on startup (spins but very slowly). If i turn the breaker on and off its about a 75% chance it kicks on and everything is fine. Could this be the module going bad? Great video btw i will be watching more. First video i have found like yours ty.

My Climatemaster ECM blower motor makes knocking noise on start up. Does it need replacement in the near future? Or it can be repaired? Thank you!
