Fuse in Microwave blew , now starts running when door is opened

Yesterday the GE Profile microwave about 5 yrs old was DOA I opened her up and found the MDA20 Fuse was blown, I replaced it and all seemed well til today and now the microwave starts "running", with fan lights and all when the door is opened. It appears to work through panel operation as well. Is this a bad Door switch condition or are these 2 conditions related ?

    I think that you are correct in your diagnosis.. I took out the Door Switch assembly, ohmed out the switches..all good. but noticed the bottom switch connector was discolored by heat and the plastic showed signs of melt. I replaced that switch and cleaned and lubed the actuator rolloer moving part of the assembly.. behold it worked...but today it has started getting flaky again.. guess Ill replace all 3 switches and try it again! Thanks for the response.

When you set heat time and hit start button the light and fan come on for a second and then everything shuts off and 4 8's are displayed. You can set the clock but when everything shuts off you have to reset the clock.

No power - blown fuse?


If it was run without the fan a thermal protect device was more than likely taken out. Check for that and replace the fan.

My ge profile spacemaker II microwave went dark, no lights of any kind and no sound or response when pressing any button. tried resetting the circuit breaker but no change


Did you check the internal fuse? Often when everything is dark the fuse that protects the microwave is blown. Take the old fuse to your local hardware store and they will have a replacement for you. Should cost less than $5.

GE Profile - Fuse blown. Replaced it. Hear click when start


Fuses usually blow for a reason, there is or was a short. I have a tip which may solved your problem at http://www.fixya.com/support/r4265491-replace_bad_magnetron It explains how to check all the components. If only your display is working you know the transformer is ok but your problem addresses a problem that you do not see very often. You may have a bad control panel and that is why the replacement fuse did not blow. Whatever was shorted is now open. If you follow my instructions in the tip and find no problems I would replace the control panel. http://www.repairclinic.com can supply the parts. Let me know if you need more help.

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.

I have a GE microwave that simply stopped working.


If the fuse is good, it may be an open thermostat or thermal cutout (TCO) / thermal fuse on or near the magnetron or on top of the cavity / body of the oven.

There should be a "mini-manual" (tech sheet) hidden inside the unit behind the control panel or hidden on the left side behind the grille, which is very helpful when troubleshooting, testing, and locating components.

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.

Accessing some components for testing and possible replacement will require you to remove the oven from the wall.

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

I have a GE Profile spacemaker 2.0 microwave and it just quit working on me. Sounded like a fuse popped?? I verified that the electrical outlet was working. Is there a fuse to replace inside the microwave?


Hello. You have isolated the problem.

Usually, when your microwave oven doesn't work it all, the internal fuse (thermal fuse) is blown. This fuse protects both you and the oven. When it blows, you need to have a qualified appliance repair technician replace it.
