Chances are you have a failing high voltage transformer.

Often there is a "mini-manual" hidden inside the unit behind the control panel or hidden on the left side behind the grille, which is very helpful when troubleshooting, & testing.



At our Web site, we have a video available showing how to remove a typical over the range control panel assembly in under 5 minutes.

See these files:

Here is a link you or someone you know can use for high voltage section test help, but read the safety warnings first:

You can find links to helpful exploded view diagrams and part ordering help here.

I'd recommend that your bookmark this link to your favorites.


Accessing some parts may require you to pull the oven from the wall and remove the cover.

If so, the installation instructions are very handy, and it's best to have two people since the microwave can be heavy and awkward.


You can download Maytag owner's manuals and installation instructions here.

SOURCE: electric dryer trips circuit breaker after about 5

Most likely culprits are the thermostat (or a short in the wiring related to the thermostat) . I am assuming it is a normal current breaker and not an earth leakage breaker. It seems likely to be the thermostat as that probably switches after a few minutes (whereas the element which is also a common failure is on from the start of the cycle, so if there was short in the element that would take the breaker out immediately).
Does it do the same whatever heat setting you select?
If you switch it back on before letting it cool to much does it trip sooner?
If the time it takes to trip changes when you change the heat setting that would point to the thermostat/wiring too.


I hope I have been of help but please do not hesitate to ask if you have any further questions.
