SOURCE: jenn-air microwave JMC 7000 ADB has no power

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.

I have the same problem every time I use the oven for a long time and then use the micro.
Solution is simple, yet unbelieveable.
This is a toggle switch. It is located on TOP of the oven box.
It is almost impossible to reach...but once reached, all you have to do is push it and it resets the micro.
1-remove the "frame" around the micro.
2-pull the micro out (use 2 people) far enough so that you can reach your hand - or I use a wooden yardstick- to toggle the thing. It is VERY tiny.

It's either the fuse or the thermostat on the magnetron.

I have a neff B6774N0GB combi oven. Activated the hot air button and it has tripped the circuit breaker. Fan element examined and looks perfect. Oven is isolated from other appliances


The hot air function uses a great deal more current than the other functions. Check the tag on the oven for current requirements, and check the rating of the circuit breaker in use. If the breaker is rated lower than the ovens rated maximum current draw, it will trip under the load. If the rating of the breaker is above the ovens maximum current draw, and there is nothing else plugged into that circuit, the breaker may need replacement.

MICROWAVE OVEN "DAEWOO" MODEL KQG-868G PROBLEM :


There should be 3 'fuses' inside a microwave. The 'line' or monitor fuse, the magnetron fuse or TCO (thermal cut out) and the cavity temp fuse. I'm trusting that you have verified that the outlet is 'hot' first. Be careful !!

Internal fan came on and is running when microwave is not running


might be sticking relay.

or the magnetron tube is soo hot that it kicks the fan on (but it happens rarely).

check the circuit where the relay connected to blower.BUT be sure microvave capacitors have 5000 volts in them.Short them first other wise forget to open it.

thanks
please rate my work

Microvave not heating the food




It sounds like the magnetron may have either failed or is not being supplied with the extremely high voltage required to run it.

YOUR SAFETY IS PARAMOUNT

This is a job for a professional but if you are safety clued up, here's instruction.
Make sure the !!!!any capacitors are discharged!!!!! before attempting any sort of repair.
Check the door interlock switches first then the high voltage diode with either an AVO model 8 or moving coil meter on high resistance range for short circuit, (DVM's won't show the fault!), the capacitor can fail and go short circuit, the feed fuse on the primary of the high voltage transformer and then finally, the magnetron is best checked by substitution.
Hope that helps.

Microwave won't turn on. Seems like it is not getting power. I checked breaker. I am looking for a fuse. You know where one is? It is a GE Spacemaker(2 yrs old) model # JVM1440WH04


  • Make sure that the microwave is plugged into a grounded outlet. It must be a 3-prong outlet.
  • Make sure the clock is set.
  • Check to see if a programming sequence was entered. Sometimes improper programming or a program sequence such as delay start can cause the touch panel to be non-responsive. Unplug microwave or turn off house circuit breaker for 30 seconds. Plug back in, or reset circuit breaker, and try reprogramming unit.
  • Check the house circuit breaker or fuse box. If the microwave is DEAD and there is no display and nothing works- the problem could be a blown fuse or tripped breaker.
