Our 5-year old Whirlpool duet electric dryer trips one of the circuit breakers and continues to run without heat. If we reset the circuit breaker, the dryer will operate for a while and then trip the circuit breaker again. This happens an average of once per load. I followed the Tech Sheet and activated the Diagnostic Test Mode, obtaining an Active Fault Code of F01. The Tech Sheet said I should replace the machine control electronics assembly, so I ordered the part (AP4373582 (W10174745)) and installed it, but the same problem persists. I replaced the original machine control electronics assembly and have returned the replacement part. Any suggestions for next steps?:confused:

Is your dryer a dedicated circuit or do you have other things running off the dryer circuitry in your house? Also how old is your breaker panel? Alot of times it has nothing to do with the dryers and it's old or bad/shared wire or an old breaker that's causing this problem. Once you figure that out if you don't then check your wiring harness for shorts and check your tech sheet and the complete circuitry that has anything to do with the heating portion of your unit...Dryers will work on one electrical phase but it's just for motion and the other is for heat so something in your heating circuit is causing it.............check your themostats/thermistors......thermal cutoffs......heat element (you may have a faulty heat element which is common from your complaint but generally if a heat element is bad it doesn't work at all or it stays on all the time irregardless if the unit is turned on even if it's plugged in some elements that are grounding will stay hot just being plugged in).....

I would check the heating coil first.
Unplug the unit and both wires from the heating coil.
Measure the heating coil, it should be 8 to 12 ohms.
Then measure from each heater connector to machine frame. Be sure to find a place with bare metal.
If the heating coil breaks and grounds in such a way that there is part of the heating coil grounded on the centrifugal switch side, then it can pull too much current but only when the motor is running. |

Thank you for your advice. The dryer is on a couple of dedicated circuits. The breaker panel is about 40 years old.

We had the two circuit breakers replaced and that seems to have done the trick. Thank you for your advice.
