Dryer heats sometimes and other times it does not heat even after repairs

Dryer Repair
1

Brand: Roper
Model Number: RED4640YQ1
Main Symptom: Dryer heats sometimes.
What happens & when: I can run a load and it dries and run another load, and it doesn’t even heat up. I keep the lint trap and exhaust very clean. I’ve replaced the following with OEM parts from APP.com : Heating Element, Dryer Repair Kit, Felt Drum Seal, and Front Panel Felt Seal. Dryer tumbles well and quietly (now with the new parts!). Why doesn’t heat each time using the same setting?

Error Code (if any): N/A
Parts or tests already tried: Heating Element, Dryer Repair Kit, Felt Drum Seal, and Front Panel Felt Seal

Does it only seem to do this if you run back-to-back loads or can you start a load with the unit completely cooled off and it may or may not heat?

Are you always running the same cycle? And what cycle do you mostly run?

It has happened with cool down times between loads. I generally use the “timed cycle" which is a high heat cycle. But I have used the other cycles which includes low heat cycle and another high heat cycle.

Thank you

More than likely a bad timer as these are known to do exactly what is happen to you.Contacts in timer are cheaply made and become pitted and open up under a load as in back to back loads of laundry! here is the tech sheet!

Thank you bigbuck1. I looked up the part on APP.com and the part description says the timer is for a washing machine, not a dryer.

I agree with bigbuck’s assessment, with it being intermittent and not seeming to follow a pattern I’d look at replacing the timer .

W11043389 is the correct timer part # for this dryer, the parts description is wrong. I’ll send that over to be fixed.
