I found a few similar posts on other brands, but nothing specific to this one. As far as I know there’s no belt switch in this dryer. The motor (which was replaced about a year ago, maybe 18 months) fires up but stops when the button is released. So while it’s not impossible for the switch to fail, it seems unlikely. But still… ?
Anyone familiar with this specific model (Roper / Whirlpool), about 10 years old? What how can I test?
On this style that would be a switch in the motor, part # 279827, that is not closing to allow the dryer to continue running after the start switch is released. The only other possibility is the wire that runs from the motor to the start switch that provides neutral once the motor has started and the start switch has been released.
You can test for voltage to chassis ground on the Black wire in the 6M terminal at the motor with the timer set and the motor running, if you aren’t getting voltage then that switch in the motor hasn’t closed. You can also disconnect the connector from the motor and take a continuity reading between the Black wire on that connector to the Black wire at the start switch, if this reads open then there is a wiring issue between the start switch and the motor.
Thank you very much for the detailed information. I’ll check that out (as soon as I’m through replacing the front wheels on my lawnmower… it’s always something!).
Not gonna look that gift-horse in the mouth, but I’m also gonna hang onto the info I got here just in case. The fact it didn’t work yesterday but did work this morning points (in my mind) to the motor switch sticking. Whether due to heat / cool changes, lint, dust, whatever, maybe that’s what happened.
A further factor is, the motor is actually about three years old, not one. But more importantly it was replaced by a service company (bought out from the deceased founder) who later installed cheap, apparently used, aftermarket tub struts on our washing machine – and claimed they were new.
We’ve since left them far behind, but now I don’t quite trust the motor anymore…
