Best part when you explain how it works and how to troubleshoot it. I’ve become so good at my job cus of your channel and now I’m on the process of preparing for contractor license

Thank you so much for your encouragement! I needed to hear that!

Just wanna thank you so much for all this amazing videos you’re making for us as technicians to gain more knowledge and serve the customers better. God bless you I’ve learned so much from your channel.

I showed up to a furnace recently installed by someone else. Diagnosed a bad board, got a new board in, discover a rollout switch also triggered. Got the furnace running; the combustion is TERRIBLE. Weak, orange, pungent flame. Check gas pressures; they are perfect. Finally realize this thing is trying to burn LP and doesn’t have a conversion kit 😅

@misfitpilgrim7967 heck yeah, good on ya. I do not think I've been onto these guys for much more than several months. Pretty much everything is on point, and I'm a field service tech who loves continuing education[for whatever that is worth]. Sometimes, I learn a trick or 2 here, but I always get a good reminder of professionalism and how to relax and go through the motions of testing.

Good video Craig. Thanks for posting. One concern though. I noticed the level bubble in the thermostat was a little bit off.

Very good video. The only thing that had me confused was the fact that you referred to the Manifold as the “Main”. It’s like people calling the Engine in cars a Motor. Engines are gas expansion driven (steam,gasoline,diesel,alcohol,kerosene,moonshine,etc),which is directly opposite to a compressor,while the Motor is electric powered! I’m not being nitpicking,it was just an observation!

Good video craig, these days at least in my area we dont see many intermittent spark systems,seems like everything is hsi now. So its good to teach this because its not really taught enough and when a newer tech comes across one they have no clue the sequence of operation so they have no clue where to begin looking for the problem. That turns into wishful parts changing with fingers crossed lol. If the problem is a poor ground connection all the new parts you can throw at it will do nothing.

Intermittent spark ignition modules are still used a lot especially in commercial equipment in residential not so much anymore

Good morning, excellent explanation and I like your videos, you know a lot, I have a question about my furnice, when it calls to turn on the sparks it clicks for 30 or 40 seconds and it turns on and works well, what could be the reason, thank you

Hey question forya craig, on the setups with the seperate flame rod completing circuit back to the sense terminal, what amperage is good/bad coming back to the control? Is it pretty much the same as an hsi setup where you want to see at least 4ma?

Hi Craig do you have the part number for that pilot sensor? I need one!

This all a bit oldskool now in the UK. Very little with PP

is it OK if I install needle valve after the gas valve so i can control the gas pressure into burner?

Hola! Tengo un problema con mi horno, no prende el quemador y ya cambié la válvula, el problema será el módulo que manda el voltaje?

On a previous 410a charging video, you charged the unit through the low side. Is it safe to add liquid knowing that’s it going to the compressor?

@albotiger7268

It is safe to slowly add liquid refrigerant through the suction side as it will usually flash into a vapor before getting to the compressor

My furnace has an intermittent issue. The thermostat calls for heat, and the inducer motor/fan starts up, and runs about 7-10 seconds, and then shuts of for 1-3 seconds, and then kicks back on. After 2-3 times of doing this, the igniter finally lights the gas, and it works as normal from there. It does not do it every time - sometimes it starts up on the first try. My guess is the NEST thermostat may have an issue? (The entire heat/AC system is about 12 months old, both inside and outside) - It occasionally did this with the old system as well, but very rarely. They did run a new thermostat wire when they installed the system. Since the thermostat is the only thing left from the original unit, I suspect it. Any idea if these tend to fail frequently? (It is about 4 years old)

Sir i am also a AC technician is there any vacancy?

I was wondering if you can help here. I have an attic unit Trane (lays on the side horizontally) We just had a week-long of zero-degree weather end of January in Chicago, before the arctic blast the temperatures outside were 25 to 30 degrees I was reading a nice 96-98 degrees using the red dot temperature thing to take the reading from the supply registers. Once the big cold blast hit as temperatures were falling to rock bottom my nice 97-98 degrees at the supply registers started slowly turning into 87-89 degrees at supply, later in the night that 87-89 degrees now was down to 84-85, even later as the night went on more my supply was now down to 80-82, and by morning we are at zero outside and my supply vents are down to 78-79 at the registers and just sat there. What the heck could be causing this? I had to leave the house for a hotel because it was 56 degrees inside!!!! This is NOT an air duct leak, I went up in the attic and right at point exit of the furnace I was getting 80 degrees coming directly out of the furnace itself!!!! This is driving me bonkers! I have a Nest so I can monitor the inside temperature without being home, could this be limit-switch and cutting my burners off "thinking" its overheating? After the cold snap has ended and temperatures rebounded back into the 20's and 30's I was back at that wonderful 97-98 degrees out of the registers. Where was my 97-98 degrees during the coldest time???? And no, I have the cleanest air filter in the neighborhood, nothing is blocking ANY cold air returns, all registers are fully open. Please don't say the filter is dirty like everyone else says because I even took the filter out, and it still ran like this. Please any help here would be greatful.

I have exactly same setup. Is there an easy way to reduce number of burners? My boiler is oversized and I wonder if I could save some gas and make the temperature maybe more stable

@HVACRTECH-83

No, boiler is designed for the burners it has, underfiring is just as bad in the long run than over firing. Will cause condensation and severe rapid corrosion to your boiler and flue pipe. It's a shame so many systems are not sized for the home/building

​@@povoljan13they are manufactured with jacket insulation, insulating it poses a fire danger and saves you nothing. The heat is being moved to warm the cool areas of the house, so insulation in that vessel saves no output as the output is always being used to heat the space.

Why does mine prove the pilot kick the main burner on then it goes out and starts over sometimes it only does it once sometimes it does it 5-7 times before it stays lit

I should check for 24 volts to be on the mv when it shuts off if it’s still present possible solenoid in main burner issue it is a Honeywell controller I grabbed a used one off a guy to try but the spark wire is different been doing it for 7 years that I lived here it’s annoying to hear the process carry on so long

I appreciate you asking this question, Im also having this exact same issue with my water boiler and I also have this same setup. I already replace the ignition control board with the same one, and the spark flame assembly. Im guessing the gas valve could be culprit.

My ignitor will not spark. What is the issue?

I’m dealing with an issue where when the thermostat is NOT calling for heat, the gas valve stays open and the flame keeps going. To turn off the heat, I have to flip the switch.

Your thermostat is probably defective and keeping the contacts in the thermostat closed between terminals R to W. Replacing the thermostat should resolve the issue
