Always Great videos. Listening to a podcast a while back, they shared an acronym for the sequence of an Integrated Furnace Control and it went like this "Take It Slow Its Gonna Blow" , "T" is Thermostat , "I" is Inducer Motor , "S" is Safety (Pressure Switch) , "I" is Ignition , "G" is Gas , and finally "B" is Blower Motor" Hope it helps !

Most of time, it’s cold solder joint. During auto soldering process, most thin parts are ok, but larger parts, such as relay legs or power scr connections don’t have enough time or heat to melt the solder, causing cold solder joint. I use x10 or x30 magnifier to check those larger glob of solder. I fixed refrigerator and AC card. Once fixed w/o using costly parts, they seem to work forever. Ex USAF and LM guy. In other KZitem site, many thanks from viewers. Thx

As a newb your videos have been vital; THANKS!!! The board series you've done have been great! I studied them all last weekend; had a Lennox G24 that wasn't operating, just that "click" at the board and GV when trying to light. Went through the OofOp, got hung at the GV. Tested all mech components; OK. ohms and voltages OK til I got to the GV on the board. It was sending random shots between 25v and 17v with each "click" to the GV. The ambient temp at the time was running in the low 50s. After doing other research, I heated the GV up to just warm to the touch, fired it up and away it went! The house is in transition I guess, they want to keep temps lower until occupied but I have them keeping it warm until I get a new board in. I don't think it's the GV, I think it's the low sporadic voltage not strong enough to pull the plunger on the GV when it's cold, but I'm not 100% sure about that. Guess I'll know for sure when I see what V I get off the new board on the GV. Your opinion would be appreciated....

Very interesting! The best thing to do would be to pull off the hot wire from the gas valve and measure the voltage when the wires are off of the load. This would be when the wire is disconnected from the gas valve with the power off and then turn the power on and let the sequence for heat get to that part and measure it. Make sure you are getting 24v to 29v there without a load.

I recently had trouble with my heat pump defrost board with adaptive demand defrost. Tech replaced the board and thermistors, but I found the information on ADD for heat pumps was sparse. I was able to piece together enough information to get an understanding. Of course, there's no info on the algorithm used. I got interested because the tech moved the termination temp jumper from 70 to 50 erroneously thinking it worked like the run timer on timed defrost boards. Didn't impact my repair, but made me curious. I didn't find any info on the best termination temp except for refrigeration where you want it a low as possible to avoid cycling the product. My board comes defaulted at 70 but I saw others that came set to 50.

What would cause a blower motor to run slow but then when you reset the power to it runs normal for 5 or 10 minutes then goes back to running slow? Should I be focusing on the blower motor module? Blower motor? Or circuit board related like a relay? It will run slow and then once I turn power off and turn it back on it runs at full speed like everything is perfectly fine but only last for about 5 minutes before it goes back to slow and the motor makes some noise like it is trying to go faster....

It’s not something to understand. Only memorize. Draft inducer motor, pressure switch, ignition, gas valve, flame, and finally blower motor. If something drops out of that sequence, you know where your problem is. Most boards have diagnostic codes that flash on the indicator light.
