Im no expert but it seems everything is working like it should except the gas valve. For a more expert opinion you might try googling your model furnace and bad gas valve and see what you can find there. My thoughts from the beginning. What he should do is call an HVAC service next time instead of jacking off not knowing what he's doing and looking for advice on the web, smh.

There is plenty of knowledge here that helped him trim down the list of possibilities. However I would suggest not measuring a live circuit for resistance. You can get both false readings, and possibly damage the meter. All resistance/continuity testing should be done with the power off.

The pilot light went out this morning and I have it lit again. The pilot light stays on but the main burners will not turn on. The induction motor runs. I changed the thermocouple but still no luck. Anyone have any ideas? It is a Nordyne M1GH 090A AW. Gas valve. Quote Link to comment Share on other sites More sharing options...

Neal You can trouble shoot switches in a 24v circuit like Tom had him do......not going to hurt anything and the specific resistance isnt important. The other issue with troubleshooting those switches via resistance when you dont really know what you are doing is you will read through the control transformer and may get confused sometimes. I prefer checking for voltage across switches in circuits or checking both sides to common etc. That is much more reliable Quote Link to comment Share on other sites More sharing options...

f7ben Posted April 26, 2018 Share Posted April 26, 2018 Tomas......disconnect the wires going to the gas valve and check the resistance of the coil. Should be some small amount of resistance there....a few ohms etc. If your meter reads a one you have an open coil although if the valve itself was clicking that is not likely. If its a sticking valve do what moto said. Beat its ass or just replace it Quote Link to comment Share on other sites More sharing options...

Neal I dont think they sell meters any more that would become damaged checking for ohms on low voltage circuits I have a couple cheap meters and have fed them 120/240v in ohms accidentally many times.

If your ignitor has opened up everything will check out, and if the solenoid on the gas valve is ticking it could be that. Looks like a small black carbon spiral.

I get both points. Hopefully Thomas realized this forum probably isn't the best place to seek some advice. Because OMG. There are much better forums and sites to seek advice like this. This place (and others) can turn into a full on clown shit show for technical advice. Most would be better off grabbing a hammer and smashing whatever they are trying to fix to see if that works. 2 Quote Link to comment Share on other sites More sharing options...

Lmao it's not like he's getting advice on installing a new heat exchanger or something. No one is going to die from replacing a bad sensor. Jesus.
