There is an internal fuse. Be careful high voltages present even if the microwave is unpluged.

Good luck

A microwave can be dead for many reasons.

It may be the fuse, which is usually located behind the grille or 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 TCOs or thermostats, if it has a hood fan thermostat, that should read open, as opposed to the others, which should read closed.

If the cavity thermostat needs to be checked or replaced you'll need to pull the oven from the wall, in which case you can download GE owner's manuals and installation instructions here.

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.

There should 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.

You can usually find helpful exploded view diagrams by entering your full model number here. Once you have the part numbers, though, I would suggest ordering parts here at a much lower cost.

SOURCE: dead microwave

There are replacable fuses inside. Taking the microwave apart requires removal of a lot of screws and the cover that can be rather bulky. make sure it's unplugged and safe before you begin. you can get replacement fuses at radio shack, ect. be sure to buy the same type and amperage. if the blow a second time there may be other issues.

SOURCE: No Power, No LED's. Circuit breaker OK

There is an internal fuse, however to access it the unit must come out. The outer case will need to be removed. The following link will take you to GE's website where you can get installation instructions. The fuse is available at ther parts site, but you can get a new on for less than a dollar at radio Shack. Take the fuse with you.

Hi I have a Samsung SMH9187 micowave that is dead (no display, light, fan, mirowave).


Sounds like the main fuse blew. It's either near where the power cord enters the cabinet, or behind the control panel (if an over the range unit).

You may also have some type of failure in the high voltage circuit; based on your description of the symptoms.

Unit was working than just shut down, the display went dead.


hello,

the solutionhas noting to do with reset button or code

what the problem is from the element (heat provider)it is always is silver colour all it means is there is disconnection from it or it is bad.

what you need to do to fix up your oven is to unscrew it and then trace down the wire to the heater (element) but if you did not see any sign of disconnection then you will have to make a change of the element it mean bad .

thank you and thanks for using fixya.

Oven has been working fine. Heating a cup of coffee it just stopped dead. No display. Nothing. Power to outlet working fine. Is there a reset somewhere?


Mine did this when my wife had it on full power for over 10 minutes. We left it set for 15 or so minutes and it came back on. It did the same thing when my niece was heating a liquid with some metal in it. It eventually came back on. There must be a thermal circuit breaker inside the unit. Yours may have a fuse or some sort of circuit breaker inside it, that needs replacing or resetting. Then again some units have a fuse that goes out when the Magnetron shorts out, or goes bad. This would require replacing the Magnetron as well as the fuse.

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.

There won't be a reset button.

Is it dead? No display, no lights, etc.?

If your outlet is live but your microwave is dead, then you likely have an open internal fuse, thermostat or thermal cutout.

Please post back if you need more help and think you or a friend want to work on it.
