Question about Microwave Ovens

Open Question

Je1860sb Our power flashed off and then on again this morning. When the microwave came back on the display lighting was dimmer. I have checked breakers and none are triggered. When I tried to heat something it runs but with very little power and it doesn't seem to heat much at all.

SOURCE: Cannot heat

Sounds like it overheated, tripped the thermostat, then the thermostat reset. Chances are you have a bad magnetron. GE may have a campaign (not a "recall", mind you!) to offer free replacements if yours is a model that has a known history of problems with the magnetrons. I would call GE and ask them about that. *grin* GE Answer Center 1-800-626-2005 24 hours a day, 365 days a year

SOURCE: Microwave Fan won't shut off, no display

Depending on which brand you have I would think that the Thermal switch on top of the magnetron or one of the door switches has probably given up the ghost. However, if the display does not come on you probably have a micro or Psu fault on the display panel. Not to be attempted if you are not familiar with microwaves or electronics. Please unplug before opening. Good Luck, JUS004

SOURCE: No power from Whirlpool.

The problem was a defective switch. There are 3 switches on mine. 1 on the top door latch, and 2 on the bottom. one of the switches on the bottom connected the power and neutral together, unless it was activated at the same time as the other 2, causing the breaker to trip or the internal fuse to blow. When unhooking the wire going from this switch to the other switch, everything works great now. Though I still need to replace the switch.

And for Basic 1. Yes my microwave did have a fuse in it it's ceramic, I got a pack of them at Radio Shack 4 for 3$ 250V 20 Amp. There should be a wiring diagram inside the microwave, mine was inside a black bag, so it may be hard to see.

Mine was up top next to the fuse behind the Plastic Grill and then a small metal grill. Some are behind the control panel, to fix this remove the screw at the top and then slide the control panel up and it should unhinge.

Sorry my Clarification Request came out as a single blob of a paragraph.

That's not how I typed it. I never write that way!

So I've pasted it here, but as a solution.



Magnetrons generally should last about 2000 hours, but several factors can shorten that.

If it's not OVER ten years old (from the purchase date or the date on the tag inside the unit) then the magnetron is still under warranty.

From the owner's manual:

"For the second through the tenth year from the date of original purchase

"The magnetron tube, if the magnetron tube fails due to a defect in materials or workmanship. During this nine-year limited warranty, you will be responsible for any labor or in-home service costs.

"For the above limited warranty: To avoid any trip charges, you must take the microwave oven to a
General Electric Customer Care® servicer and pick it up following service. In-home service is also
available, but you must pay for the service technician’s travel costs to your home."


GE Customer Service is here, and you can verify the warranty status and find your nearest authorized servicer.

If you're sure the magnetron's bad, it's still under warranty, and you or a friend are handy, they will send you the magnetron to do it yourself. Call them at 888-239-6832.

Be persistent. You may have to speak with a supervisor.


It does sound like the magnetron overheated and the magnetron's thermostat opened until it cooled down.

An overheating magnetron can be due to:

  • operating oven without cover(s) in place
  • wrong magnetron installed in oven
  • an old or otherwise failing magnetron
  • cracked magnetron magnet
  • improper power line voltage (should be 110-125VAC)
  • foods low in moisture (popcorn & bacon, e.g. - add 1/2 cup of water in rear oven)
  • failed or inoperable cooling fan or hood vent exhaust fan
  • deteriorating foam weatherstripping seals in air ducts or on outside cover
  • blocked air vents (dust, animal nest debris, insufficient free air space behind & around oven, etc.)
  • clogged or greasy charcoal filter or grease filter
  • blocked duct in hood vent exhaust
Since yours is a counter top model, there are less of those factors to worry about.

When you hit Start to microwave, do the inside light, cooling fan, and turntable all come on?


Any unusual noises? Is it louder or quieter than usual?

We have a sound clip of what a microwave should sound like when the cooling fan and high voltage section are operating here.

You can find helpful exploded view diagrams and order parts if needed by entering your full model number from the tag on the oven here.

Let us know what you find out or decide.

SOURCE: Microwave shorted out when metal grease filter contacted inside

It might be that the internal power fuse of the MW may have blown. You may have to just replace that fuse if possible. Other wise the electronics (most likely a circuit board) may have been blown.

How to set the clock on ge space maker micro wave


http://products.geappliances.com/appliance/gea-support-search-content?contentId=17872

Quoted from link above:

To set the clock on most GE microwaves:
  1. With the microwave door closed, press CLOCK.
  2. Touch number pads that reflect the time of day (1:45 would be 1, 4, 5).
  3. On some newer models, indicate AM or PM for morning or evening.
  4. Press CLOCK or START to lock in the time.

If you prefer not to display the time:
Disconnect the power for 30 seconds. After restoring power, do not set the clock. If your model has an ON/OFF clock display, you can choose not to have the time displayed. To choose this option, press the 0 pad for about three seconds. To Turn the display back on, press the 0 again.

The magnetron may have overheated due to a failure of the internal cooling fan, blocked air vent in the back, or a clogged filter, if so equipped.

You can find links to helpful exploded view diagrams and part ordering help here. I'd recommend that your bookmark this link to your favorites.

There should also be a "mini-manual" hidden inside the unit behind the control panel or in an envelope on the inside of the cover, which is very helpful when troubleshooting, & testing.

Feel free to contact me directly (and please include your full model number from the tag in or on the unit) for a free estimate and free tips & do-it-yourself advice.

GE EMO3000 Over the oven Microwave


Do you know if the fuse blew again? You may have a problem with the powers supply section that powers the main board. The main board controls the display and receives input commands from the keypad.

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

Good luck!

Whirlpool Microwave Model MH3184XP will not power up after power failure


The first thing to try is a "hard reset". Unplug it from the power line for a few minutes, plug it back in, set the clock, then try again. Let us know if the hard reset doesn't fix it.

If not, then you may have a problem is on the control panel, which we repair nationwide for $39.95 postpaid.

Assuming the entire power line from the breaker to the microwave cord is okay, it's almost certainly a bad connection on the circuit board of the control panel assembly. For reference, we repair these from all over the country for $32.50 postpaid.
