Hello, I have a electric maytag bravos xl MCT dryer. Recently all functions worked but no heat,except for timed dry. 2 weeks ago the timed dry function stopped producing heag as well. I replaced the thermstat, thermal fuse, and heating element. Not the normal mode runs for 5 minutes and shuts off, still no heat, nor do any others still no heat. Any help would be appeciated

There doesn't appear to be many possibilities in the heater's wiring circuit.



Most of those you say you've already checked. Did you test each with at least one wire removed from the component before testing?

Sometimes a break is caused by component failure itself while other times the connecting wiring is the source of the open circuit. This is why the component itself should be tested and not just the circuit it may be connected to. To do this at least one wire of the connecting circuit should be...

Has anyone confirmed the full 240 volts at the dryer outlet and at the dryer's main terminal block? That would usually be one of the very first things needing doing for a 'no heat' complaint.

If the parts were tested properly and they tested Ok, that pretty much leaves the wiring, the electronic control and the heater circuit of the motor switch (which is pretty rare to fail besides a wire burning off).

Only the electronic control itself would be affected by changing to a timed setting so the control might be most likely to be responsible.

I do not know how it can be confirmed though. Maybe try to isolate the K2 'Heater Relay' on the board and see if power is flowing through it when the dryer should be heating?
