The control panel has built-in surge protection, and the high voltage probably tripped that. It will have to be repaired, which we do nationwide for only $39.95 postpaid. By rights, I would say the electrician should be the one to see to the repairs, including removing the control panel assembly to send in for repair. We have *critical* safety & disassembly info at our site, which is linked at our listing here on FixYa: http://tinyurl.com/yzjozk You can find helpful exploded view diagrams by entering your full model number (without the suffix) here: http://tinyurl.com/gv383 Please let us know if you have any other questions.

SOURCE: Replacing the fuse of a MCO160UW

A microwave can be dead for many reasons.

It may be the fuse, which is usually located on the floor of the oven behind the control panel or between the door switches.

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.

If it goes dead for a while during or after cooking then comes back on, the magnetron is probably overheating and causing the magnetron thermostat to open.

Then when it cools, it closes the circuit and allows power through again.

When checking thermostats, if it has a hood fan thermostat, that should read open, as opposed to the others, which should read closed.

If it went dead almost immediately after pressing the Start pad, that's usually a shorted high-voltage capacitor.

If it went dead a few seconds after pressing the Start pad, that's usually a failing high-voltage transformer.

If it goes dead or blows the breaker (or GFI) when you plug it in or open or close the door, then there's a problem with a door switch or door switch mount.

If it's intermittent or random, it may be a bad connection, usually on the control board or a loose fuse holder, or even an intermittent fuse.

You should do a continuity test on the fuse while it's in the holder (with the microwave unplugged, of course) then turn the fuse by hand or take it out and put it back in, then test it again.

If you remove the fuse, then press the meter leads against the ends, it can allow internal contact to be made and make a bad fuse appear to be good.

If you or someone you know decide to look into it, we have critical safety information and disassembly information at our site, and our link is at our listing here on FixYa.

There may also be 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.

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.

You can usually find helpful exploded view diagrams and order parts by entering your full model number here.

It may be the fuse, or the magnetron thermostat (thermal cutout ./ TCO) or the oven cavity thermostat.

The first two can be accessed via the control panel opening, but if you need to check or replace the oven cavity thermostat, you will need to remove the oven form the wall.

Removing it from the wall is ideally a 2-person job and you should have your installation instructions handy. If not, you should be able to find it here.

Be sure to unplug the oven before you begin.

SOURCE: Reset for GE Microwave?

There's no other reset function. If a reset (unplugging) does not correct it, it will need to be repaired.

If it's less than one year old, it should be fully covered under warranty. I'd suggest contacting the manufacturer to get it fixed free. GE Customer Service is here.

Yesterday my GE JE1390WA, stopped working. After being dead for about 30 minutes it came back on, but sounds like a fan is continuosly running and says RESET. If I do nothing it makes fan noise for a while...


Please disconnect the set, open the cover of the oven , then the front panel assembly. Inspect carefully for any signs of insect/ coakroaches within the set, if so use a good blower to clean the inside, use a hot air dryer to warm for any insect dirt. once you have finished checking for any loose connections and the clean status, close the cover back and check on the set. If it does not work well try settting the clock and test. Hope this helps. Good day.

No power to unit


What has most likely happened is that somone slowly opened the door when the unit was operating without pusing the stop/pause button first. Doin this will cause the door interlock to blow the internal fuse as it is a design safety interlock to prevent the unit from operation with the door open.

Power plug unplugged

There is a 15A fuse inside the cabinet that must be replaced. Remove the cabinet screws 4 on the side and 6 on the back then slide the cover to the rear about 1/2 inch. Lift the rear of the cover up about 15 to 20 degrees and continue to pull the cover off.

Follow the power cord from where it enters the rear of the unit. The black power wire will terminate at the fuse block. Removed the fuse and replace it with an EXACT type replacement fuse. (buy 2)

If the fuse blows again there is another problem in the unit. If it works normally there is probably nothing to be concerned about. Just make sure that before opening the door you push stop before opening the door.

To re-install the cabinet cover graso the cover from the rear... holding the back of the cover up about 15 - 20 degrees and slide it back into place. Make sure to engage the side locking tabs with the front part of the chassis before installing the mounting screws.

No lights - no power - DEAD! Worked fine an hour earlier now ... nothing. Check fuse in mains box - all OK - tried it plugged into another outlet... nothing.


Your unit is dead, mains are good, tried in other receptacles, still no power. You have a bad fuse inside the unit. Unplug. Remove the cover. Generally this requires removing all the screws on the back perimeter and lifting the cover up. Sometimes they stick due to old grease, etc. Somewhere in the area of where the power cord comes in or near the transformer there should be a small fuse in a holder. It is not a glass fuse and should be replaced with the same kind (ceramic) and value. This is important for future protection. You can get the fuse at www.mcmelectronics.com . Get a box of five for future problems. If this was the only problem your microwave should work. If it blows the new fuse you could have a shorted power transformer, bad high voltage diode, or a bad magnatron in that order. There could also be a short in the board with the display but that would be unusual. Let me know if you need anymore helpl

Had microwaive on for 30 minutes with nothing in it now it won't work and light is off also. Could it be broke now???


Hello there:
from what you have told me leads me to believe that the fuse that is inside of it has blown and is in need of replacement>
to do this.
(1) remove the screws on the back for the cover should be about 6 or 8
(2) turn the unit over and you will see more screws for the cover remove them .
(3) now pull the cover off the unit it should slide back towards you ** this may be kind of hard so a flattip screwdriver is a good tool to use to get the cover to slide off.
(4) once the cover is removed look towards the front and you will see the wires and a lightbulb there should be a electronic board that the fuse is on
now simply remove it the fuse and get a new one from either a appliance store or even a automobile parts store.
(5) put the new fuse in and before you put the cover on plug in the unit and see if it all works if so great just put the cover back on and replace all of the screws and you are good to go YEA !!!
if not than the board that the fuse came from is bad and needs to be replaced ok
I hope that this has been really helpfull for you
best regards michael

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.

GE SpaceMaker JVM140001 just quit


Same thing happened to our unit. My wife had started cooking potatoes and we left house for an hour. Came back and unit was dead, nothing worked. Verified power @ plug. Unplugged, pulled control panel and checked fuse which is mounted @ top of circuit board (will now refer to as CB), back side of interface panel. It passed continuity test. Inspected wiring and was all intact, no sign of burn thru. Varistor visual also looked good, no discoloration or burns. Removed (5) fasteners that hold CB to interface and inspected back side. Noted minor "blackening" @ pin location #1 of the (5) pin plug immediately beneath fuse. Resoldered because connection looked poor. Plugged back in and tested, all features worked correctly!

You may have a blown internal fuse. While I would recommend that you take the unit to a qualified repair center, you can do a little troubleshooting on your own. You''ll need to unplug the unit, remove the outside cover and follow the line cord and you should find the fuse.

Replace it with the EXACT same value that was labeled on the original fuse. You'll probably be able to find a replacement fuse at any Radio Shack store or hardware store.

Replace the cover and plug the unit back in. Hopefully nothing was damaged and the unit will play again.

If the unit does not come back on, then there is a possibility that the unit's power supply has failed.

Please let me know if I can be of further assistance to you.

Good luck!

2 year old ge profile spacemaker Microwave lost all power


Inside unit is a cylinder fuse which can blow for a number of reasons. External cover needs to be removed to access. If you are confident in doing this and can find & check the fuse then it would be my first guess. If fuse is OK then you will need to have repaired. If fuse isblown & you replace then it blows again,you will need to have repaired. regards
