Hi guys,

My son replaced the belt & pulley on our 25- to 30-year-old dryer this past summer and it was working fine until this past week. It spins, the flame comes on, the dial goes through its cycle whether it's in timed dry or moisture-sensor and shuts off as it should, we removed the ductwork and cleaned that all out (though there was virtually no lint in there) but it won't heat up. These were all the suggestions I could find on Google.

I did look through other posts and see that it might be the thermostat, but I want your opinion.

Last night after we cleaned the ductwork, when I pressed the START button, I heard a loud screeching sound, it only lasted a second and went away. This hasn't happened before, and the dryer wouldn't heat up before that screeching sound so I don't know if it's related at all, or what caused that sound.

Thanks,
Lizzy

Hi,

It spins, the flame comes on,
but it won't heat up.
the dryer wouldn't heat up

The flame does come on?
The flame does not come on?
The flame comes on once and not again during the cycle?
With the lower front panel off you can actually watch and see what happens or doesn't happen.

No idea what the noise was.

My son took the front panel off, I turned it on, and he saw the flame. I will do that again and see if it stays on during the entire cycle.

I put in a load, the flame came on, I went downstairs about 15 minutes later, the flame is out but the clothes are toasty. SO I'm confused. My son thinks he's just been overloading the dryer. I hope that's all.

Def try a test load for 45-60 minutes and see what happens to the drying process....hope all is ok!
Intermittent heating is often the coils on the gas safety valve.....heat might even work once or twice and then fail for most or the rest of the cycle.
