A microwave can be dead for many reasons.

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.

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

If it has a hood thermostat, that should read open, as opposed to the others, which should read closed.

There should also be a "mini-manual" hidden inside the unit behind the control panel, which is very helpful when troubleshooting.

A microwave can be dead for many reasons.

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 when you plug it in or open or close the door, then there's a problem with a door switch or door switch mount.

NOTE: There should 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.

SOURCE: spacemaker quit working.....

sounds like a short in unit and if it is then must be taken apart to observe operation and failure spot. depending on the age GE has warranties that cover magnatron up to five years< most likely cause of problem> suggest calling company before procieding any further.

SOURCE: GE spacemaker otr microwave - place of fuse - how

Hello there

  1. Unplug your microwave. Although it might seem like no electrical current could possibly be running through your appliance, it could still have stored electrical current somewhere in the system. Be safe rather than sorry and unplug it before you begin.
  2. Step 2 remove the screws that are on the very edge of the back of the microwave on both sides and there are 4 or 6 screws under the bottom of the unit

  3. Step 3 remove the cover usually it will slide out towards the back
  4. You may have to use a small flat tip screwdriver to get it to start to move

  5. Step 4 If you look towards the front on the sides youshould see sonme wires and a circuit board the fuse will be on this board
  6. Remove the bad fuse . Go to your local hardware store and pick up a matching fuse. Make sure you check the model numbers of the fuse as well to be sure you get the right component
  7. . Install the new fuse and than before you put the cover back on test it out it should now work if so put everything back together.
  8. If it dosent you probably have a part on the circuit board that has blown in that caste you may want to bring it to a a repair shop and get a quote on how much it would be to fix it.
  9. Sometimes the repairs can be more than what you paid for the microwave so be carefull here ok?
  10. I hope that this has been very helpful for you
  11. Best regards Michael

My old GE Spacemaker II microwave (JEM21K001) died. I was using it, heard a little pop, and it lost all power. Is this something simple to fix like replacing a fuse or is it bulk trash at this point?


HELLO.

take on these steps to solve the problem.

Check if there is electric power on wall outlet.

If the microwave plug has fuse,check if it has not burnt.if these are okay there is need to take the last step.

things needed
1.Screwdriver
2.Ohmmeter
3.New fuse

1. Unplug the microwave from the electrical outlet to prevent electrocution. Place the microwave in a well-lit area to be able to locate the fuse.

2. Use a screwdriver to remove the outer cabinet of the microwave, and follow the power cord to the fuse. The fuse is located 2 to 3 inches within the microwave and is attached to the power board.

3. Observe the fuse to determine if it is blown. Blown glass fuses will produce burn marks on nearby surfaces, or the internal fuse wire will be black and melted, while ceramic fuses show no outward appearance of being blown.

4. Determine if a ceramic fuse is blown by testing it with an ohmmeter. If the ohmmeter reads zero ohms, your fuse is not blown. Other readings on the ohmmeter show that your fuse is blown.
5. Replace the blown fuse by popping it out of its holder, and snapping a new fuse in its place. Tighten the fuse clips by squeezing them together with your fingers.

6. Replace the outer cabinet of the microwave, and plug the microwave back into the electrical outlet. Test the microwave to see if it's working properly.

Thanks.

How to halogen light bulbson my microwave JVM3670Sk03 I have changed one I know there is another one how do i change it please advice thanks anna


That's covered on pages 35 & 36 of your owner's manual.

If for some reason you don't have yours, you can download it here.

Cooktop Light/Night Light

On models JVM1850, JNM1851, DVM1850 and
EMO4000, replace the burned-out bulb with a 120 volt,
40-watt incandescent bulb (WB36X10003), available
from your GE supplier.

On models JVM1870, JVM1871, JVM2050 and
JVM3670, replace the burned-out bulb with a 120 volt,
20-watt halogen bulb (WB36X10213), available from
your GE supplier.

To replace the bulb(s), first disconnect the
power at the main fuse or circuit breaker panel
or pull the plug.

Remove the screw at the left edge of the light
cover and push on the right edge of the cover
to open.

Be sure the bulb(s) to be replaced are cool
before removing. After breaking the adhesive
seal, remove the bulb by either gently turning
(for models JVM1850, JNM1851, DVM1850 and
EMO4000) or pulling straight out (for models
JVM1870, JVM1871, JVM2050 and JVM3670).

Replace with the same size and type bulb.

Raise the light shield and replace the screw.

Connect electrical power to the oven.

Oven Light

Replace the burned-out bulb with a 120 volt, 20-watt
halogen bulb (WB36X10213), available from your GE supplier.

To replace the oven light, first disconnect the
power at the main fuse or circuit breaker panel
or pull the plug.

Remove the top grille by taking out the screws
on top of the grille that hold it in place and
sliding the grille to the left (opening the door
makes grille removal easier).

Next, remove the light cover.

On some models, the light cover is located
in the center of the top opening. Remove the
screw that secures the light cover and lift the
cover off.

On some models, the light cover is located at the
left of the top opening. Lift the cover off.

Pinch the clips that hold the light socket in
place and lift the socket out.

Remove the bulb from the light socket by
pulling straight out. Replace with the same size
and type bulb, then replace the light socket and
cover.

Replace the grille and screws. Connect electrical
power to the oven.

Spacemaker died while operating with nothing inside


your ceramic internal fuse blew, you can get them at most hardware stores its either a 15 or 20 amp ceramic fuse, then if this blows again chk your h.v. capacitor,h.v. diode,or the magnetron tube for defects

Everything works except the heating of food


Try replacing the fuse first. Cartidge ceramic fuse.

Power off


Chances are if there is power available to the unit and it will not power up, the internal fuse has opened. This is not a user serviceable type repair. that being said, remove the cover, near the power supply is a ceramic fuse, test/replace the fuse reassemble. if the fuse continues to blow it will most likely be easier to replace the unit than to repair it

Need a schematic .


I just today had to open up my GE microwave. After I took off the cover I found the schematic in an envelope inside.

The fuse should be right in line with the black or red (hot) lead coming in from the line cord. It may be a white ceramic cylinder with metal ends.

Yes, there should be a ceramic (tubular) fuse under the cover on the top side where the power comes into the microwave.
