Ge spacemaker II microwave started humming and nothing showing on monitor

My parents have had a couple of the spacemaker microwaves mounted over the range with the built-in vent. Over time, the seal on the control board gets a crack in it and the steam from cooking below it gets up into the control board and does it in.
Even if yours isn't mounted over the range, it sounds like a main control board failure.

Where is the fuse located in a GE Spacemaker II microwave model number J EM824_ _ _ ? I can't read the rest of the model number.

If the microwave control panel doesn't light up, then your fuse is blown. unplug the microwave. unscrew the vent grill, (2) screws at the top of the microwave. then you should see 1 screw holding the control panel. after removing that screw, gently push up then out. there should be a metal plate on top of the control panel. remove that plate and the fuse will be in that opening. remove the fuse and check for continuity across the fuse. Replace fuse and microwave should begin working.

Does GE JVM1190SY Profile have internal fuse? If so, how do you access it?

yes it does, open the door and on the inside edge of the control panel is a couple screws. take them out and you can open the panel the fuse is located behind the panel in the micro up near the top.

My GE JES1656 will not work. Check the fuses and nothing blown on the panel. Tried other appliances in the same outlet and they work. Microwave oven is about a year old...any fixes??

Probably the "oven temp/flame sensor" if you make microwave popcorn and the vents on the left hand side are restricted. Gets pretty hot. This part cannot be reset and has to be replaced.

When microwave finishes light doesn't come on when door open; display keeps reading "food ready" after food is taken out--have to push the "clear/off" button to make "food ready" display go away; counter...

Shorted switch in the door latch assembly.wihout the full model number I can't tell how to get to it, but usually one needs to remove top grille, remove screw holding the control panel, remove control panel. Good luck.

On GE models, "SENSOR ERROR" appears on the display when:
  • Using the sensor feature, the door was opened before steam could be detected. Do not open the door until stream is sensed and time is shown counting down on the display.
  • Steam was not detected in the maximum amount of time. Use Time Cook to heat for more time.
Otherwise, yes, it may have a bad humidity sensor (gas sensor, as it's called) which needs to be replaced.

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

You should enter your model number as JEM31GA02.

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

GE Dual Wave II microwave doesn't work, all power controls are out. Is there a user-replaceable fuse?

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.

Ifthe 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 / bodyof the oven.

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

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

Whenchecking thermostats, if it has a hood fan thermostat, that should readopen, 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.

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

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

You should do a continuity test onthe fuse while it's in the holder (with the microwave unplugged, ofcourse) 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 meterleads against the ends, it can allow internal contact to be made andmake a bad fuse appear to be good.

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

Thereshould also be a "mini-manual" hidden inside the unit behind thecontrol panel or hidden on the left side behind the grille, which isvery helpful when troubleshooting & testing.

Oven stops after a few seconds

I like the information you give.
If the unit will work with the control Panel at a 45 degree angle it tells me you have a loose connection. The 45 degree angle puts enough pressure on the connection to keep it completed. With the Control Panel in it's normal position, the loose connection Heats and Opens the connection. After it cools connection is again made until it Heats up again. Remember Expansion, Contraction. I do not believe you have a Magnetron issue!! A Magnetron does not know if the Control Panel is at an angle.
Can you hear a slight "Click" when the unit shuts down? If so this is a relay opening. When you say you replaced the Control Board. Was this the Control Panel PC Board, or was it the Cook-Relay Control Board? A Door Switch not making solid contact can do this. Is your Door latching down solid? Check for loose connections, not open LOOSE.
