Gas Dryer is only Partialy Heating

13 posts in this topic

Hello, I have a Whirlpool gas dryer that is not quiet heating correctly. This is what it does:

1) When I turn it on after it has been sitting and is cold everything works fine. Drum turns, element glows, then the ignitor kicks on after the normal 15-20 sec and it blows flames through the vent. All good.

2) After about 1 or 2 min the burner stops, it cools down a bit then the element begins to glow again and the ignitor kicks on but it only blows a tiny flame.

3) Then after a few times of this only the element will glow and the ignitor doesnt kick on. So no flames blow through.

Question: What may be the cause of this and which parts most likely do I need to replace?

Thank You

Sorry I thought all gas and electric dryers were basically identical internally if they were made by Whirlpool, Kenmore, Maytag, etc. But here is the model number anyway LGQ9030P0.

Can I test the coils with an OHM meter and if so what should they read out to be?

Thanks

3 prong coil between 1&2=1350, 1&3=550, 2&3=1900. Two prong coil pin 4-5= 1300 problem being when they warm up is usually when they fail and with what your describing it's the coils!!! Sometimes when they fail the center of coils will be a redish , pink color!

1)

a ) depending on year

b ) Kenmore doesn't "make" anything Who Make Sears Kenmore

2) no, those Coils sometimes work when cold, but are "weak" after they're warm.

Those are the correct Coils posted above

The prongs on the solenoid coils all tested within those ranges on the multimeter for OHMs. I didn't see any red or pink in the middle of the coils either. Is there any other reason it might be only partially heating like the thermal cutoff and the cycling thermostat?

I did put new solenoid coils in though and it seems to be working fine now. Is it possible that they test good when they are cold and then after they heat up they lose continuity?

Is it a good idea to replace both coils or just the one that tests bad?

Replacing only one now may save a shekel or two but will cost you in aggra-dollars later on. Replace em both as a set.

I always replace both and suggest you do the same!!! And also clean vent and blower housing that surrounds blower to keep from having dryer fires and overheating of all components in dryer!!!
