Dryer, no heat or timer advance

Whirlpool electric dryer WED5790SQ0

No heat, timer won't advance (even on timed dry)

Hard to imagine two things have gone wrong but I guess it's possible. Have tested voltage and continuity everywhere and can't seem to find the issue. Heating element, thermostat, etc are good. Is it the timer? It's the most expensive part and can't be returned, so I'm trying to make sure before I buy and try it. Is there something I'm missing or have I checked everything I can?

Timer not advancing is timer bad. How did you check heater, Continuity Check? did you also check Both thermostats?

Reset your electrical panel breaker for the dryer. If it still won't work, check for 240vac at receptacle. Timer motor on this model runs on 240vac as does the heater element. Drive motor runs on 120vac. May be missing one leg of power supply. If you have 240vac at receptacle, check same at dryer cord terminal block on back of dryer behind small panel. If 240vac at dryer is ok, then looks like faulty timer. If you buy timer from this link, it can be returned if it doesn't fix the problem.

Did a continuity check on heating element and both thermostats. All good. Could bad timer cause heat to go out as well?

Thanks for link with returnable timer! Checked voltage at outlet and inside dryer. Seems to be getting 240v everywhere so I can't figure it out, especially the no heat. Same question above: could bad timer cause both problems?

Thank you both for your help!!

Thank you! I will order the timer and hopefully it will fix everything. I'll update in a few days.

Haoak,

I've got the same problem with my dryer. It's only about a year old and I have continuity on all the parts, but no heat and the timer does not advance. Let me know if the new timer solves your problem.
