I offer my amateur services to the elderly in my community. One of them has a built-in Jenn-air microwave over the range (not part of the range) with a date of September 1981 on it. The model # is M14001. The symptoms are these: It quit working (both clock and cooking), then after a week, it mysteriously started working again…for more than a month. Then everything went out again…until last night. During a wind storm, the power for the whole community went off and on a few times, and now it is working correctly again. My assumption is that the connection to power may be loose, but I don’t know how to access the area of the microwave where that connection is. I am guessing it might be through the sheet metal cover on the bottom…just not sure. There is no external receptacle or plug. I double checked the wiring to the circuit breaker, and it is solid. Based on the above symptoms, do you concur that it is likely the power connection rather than something to do with the microwave itself? If so, can you tell me how to access the power connection area of the microwave? Also, in case it becomes necessary, can you guide me as to how to remove the microwave? I can’t see any way to remove the microwave if it needs to be replaced. There are no external screws on or near the microwave, and nothing inside the adjacent cupboards. Thank you so much.

Like most manufacturers these days, Jenn-Air offers manuals online. I did not see specific instructions for removing the panel, but here is a link to the parts diagram which may offer some hints. You can also call or chat online with Jenn-Air Customer Care.
I hope you are a technician as there are lethal voltages inside a microwave , you could also inadvertently expose yourself to microwave radiation if protective switches are disabled or the door seals are damaged .Open the microwave top cover, disconnect the two wires going to the Power Transformer (The Big one) and connect a Dummy Bulb and Power up if the Bulb goes ON and OFF according to your settings, the control Panel is OK, or else replace .Check the High voltage diodes, Protector Diodes and the high voltage capacitors , if they are OK the magnetron is suspect. The high voltage transformer rarely fails. If the microwave is of the inverter type , forget it, it is not for amateurs to repair.
I'm afraid since Jenn Air has become a division of Whirlpool (along with numerous others) the quality has suffered.
I was going to suggest that you purchase a service manual for your unit so you could 'reset' it yourself. Service manuals can cost from $12-$40 US and in many cases obviate the need for 'professional' service calls.
However, I couldn't find one offered for your model number so your only choices are to continue to pay for 'service' or examine the guts visually to see if you can locate any reset feature.
This is what I would do.
When microwaves fail, older ones generally need a diode, a big capacitor or the magnetron replaced.
Newer units are suffering power supply failures as many have moved from the reliable but less efficient 'linear' power supplies to 'switched mode' types that are more efficient but more complex and prone to failure.
These later types usually have the word 'inverter' in the model description.
More than likely the power inverter board has been damaged and it would be best to stop using it immediately.
Jenn-air products are very good quality and quite expensive to replace. I would contact Jenn-air service and have a service tech dispatched to determine the exact problem and the cost to repair it. Jenn-air stands behind their product 100% and should be able to repair the unit for you.
Bottom line is... Home warranty companies will do anything possible to wriggle out of paying for something. (Especially if it's American Home Shield).
I'd suggest offering to fax / email photos and the front cover of your owners manual. Your model is 100% considered a built in unit and they are lying to you and trying to cheat you if they say otherwise.
I have a different Jenn-Air built in microwave & oven combination but I'm sure my solution will work for you as well.
My microwave was plugged into an outlet located on the top of the oven. This outlet has a "circuit breaker" that tripped while we were using the self cleaning feature on the oven. You just need to reset the breaker button right next to the wall oven outlet. Why it tripped is a mystery since the microwave was not in use at the time. Bad design.
Of course, getting to the reset button is your only challenge. You need to pull the microwave and oven out of the wall/cabinetry in order to get to it. The unit is heavy so you will need help. Or, call a certified repairman and they should be able to do this for you in 30 minutes or less so the service call should not run you more than @$85 if it is no longer under warranty.
I would also suggest you contact Jenn-Air to complain about this issue and seek reimbursement from them if necessary.
