We have the service manual for this model and have uploaded it to our site here to help you.

You will need the
free Acrobat Reader to view or print it in case you don't have it.

A microwave can be dead for many reasons.


It may be the fuse, which is usually located behind the grille, on the floor of the oven behind the control panel, between the door switches, or on the filter board near where the cord comes into the unit.

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.

So don't let that fool you.

If the cavity thermostat needs to be checked or replaced you'll need to pull the oven from the wall.

If so, the installation instructions are very handy, and it's best to have two people since the microwave can be heavy and awkward.

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.

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 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 & testing.

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

SOURCE: need installation instructions for otr microwave please

I just pulled my ge spacemaker xl1800 out. The mounting plate installs on the wall and two 4-6 inch bolts go through the cabinet above and into the top-front of the unit. The two top mounting holes are about 8 1/2 in. from the back of the unit and about 1 1/4 in from the side. If you don't have the mounting bracket that comes with the unit, you will have to use a 2x4 or similar to support the back & bottom of the unit.

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.

Actually, these have a 10-year warranty on the magnetron and on the halogen speedcook lamps.

GE will even send you the magnetron to replace it yourself. Call them at 888-239-6832.

The full service manual with installation instructions is here.

Part ordering help (if you need other parts) is here.

I'd recommend that your bookmark this link to your favorites.


If you or someone you know want to replace the magnetron yourself, you will need to remove the oven from the wall.

If so, the installation instructions are very handy, and it's best to have two people since the microwave can be heavy and awkward. Thewy are in the service manual.

You can also download GE owner's manuals and installation instructions
here.

If you prefer to replace it though, I would suggest doing Google searches to try to find 240V microwave ovens. They're the exception.

The F3 code keeps coming on with a beeping sound on my G.E. sensor microwave oven model number JES1456WFC001 1100 watts.


F3 means you have a shorted membrane keypad.

If it's under warranty, you should be able to get it fixed free.

The "C" in the model number means it's made for the Canadian market, and contacting GE Canada seems to be impossible for us here in the States.

So you'll need to contact GE via the info in your owner's manual.

If it's out of warranty, it's best to replace it, GE does not make parts available for JES-series microwaves.

One assumes they're meant to be thrown away when they fail out warranty.

Please don't kill the messenger... :)

Is the 1.1 cu ft 1100 Watt model: jes 1139bl sold by Home Depot the same as the 1.1 cu ft 1100 watt model sold by Lowes ? If so, what is the model number of the lowes unit ?


A quick check of the Lowe's Web site show the following GE 1.1 cubic foot microwave models:

JES1142SJ
JES1139WL
JES1139BL
JE1160WD
JE1160BD

If you still have any doubt, I'd call Lowes.

You can fix it without the aid of a repairman. Simply unplug the microwave and remove the outer casing. There should be a few screws around the bottom edge and back panel. Once you have the unit open, look for where the power cord comes in. There should be a circuit board with a fuse mounted to it. This is your input line filter. The fuse should be a 20 amp appliance fuse that you can pick up at any hardware store (Lowe's and Home Depot both carry them). DO NOT op test with the outer casing removed. Potentials of about 14,000 volts are present in the high voltage network of a microwave oven. Close the unit up BEFORE you power it back up. Let me know if this helps.

My microwave shuts off after a few mins. of use


There seems to be a rash of these units failing in this way due to bad magnetrons. The magnetrons normally have a warranty that runs for a few years. In some models, they have a whole kit they replace, consisting of a new magnetron, stirrer, and high-voltage rectifier diode. I would call GE Customer Relations with your model and serial numbers to see if yours is affected. They're at 1-800-386-1215 (8-6 ET). I would also suggest you ask them for a referral to a GE-authorized servide center in your area. Good luck. I appreciate your thoughtful rating of this answer.
