Question about GE Spacemaker JVM1640SJ Microwave Oven

1 Answer

Kenmore Microwave, overhead household, Model 721-6264900

Existing microwave has no owner's manual. "Cooking" light just went out and will occasionally come back on for a few seconds during use. Nightlight/exterior light feature works fine. Cannot figure out where/how to check/replace interior light for the cooking feature.

If there's no obvious removable cover over the bulb (and the owner's manual doesn't address it) some disassembly may be required.

Always unplug a microwave before removing or installing any bulbs.

If it's an over the range type, remove the vent grille across the top and see if bulbs can be accessed there. There may be a panel on the bottom covering the light(s), instead.

If not, chances are you'll have to remove it from the wall, then remove the outer cover. If so, the installation instructions are very handy, and it's best to have two people since the microwave can be heavy and awkward.

If you don't have your instructions, please reply back with your brand and model number.

Once it's out of the wall, the outer cover (wrapper) will need to be removed, just as you'll need to do on a counter top model.

On a counter top model, be sure it's unplugged, but otherwise ignore the instructions above this paragraph.

The screws you need to remove should be pretty obvious, but a special driver (such as a T20H Torx type or GTXH20-100) may be needed.

Be sure to put all the screws back in the right holes, since some may be special grounding screws.

Bulbs can be had in most grocery stores, hardware stores, home improvement centers, and big box or department stores.

Many models use halogen lamps. You must not touch the new one with your bare skin, as the oils will shorten the bulb life.

Tip

Or the microwave could be in "Demo Mode" - Check your owners manual. In...


If the microwave operates normally, but does not heath at all, then it can be the high voltage capacitor, the rectifier diode.or the magnetron.

The diode and capacitors can br tested. The capacitor must be allowed discharge before testing, or you risk to get electrocuted, even if power is off. Capacitors can get discharged by shorting their two contacts.
Replace the magnetron if the checks and all of the high voltage component tests are good, but the unit still does not heat.

All locations, and description of this parts can be located using the diagram here: Counter top.

Parts must be tested to find out what is wrong.

Remember that microwaves are potentially dangerous devices if not repaired properly, the job must be done by a competent person.
A microwave energy leakage test must always be performed when the oven is serviced for any reason.

Regarding parts, your model number did not return any result, contact the seller here to purchase parts. (here in UK).

No power


Your stove should be on its own breaker or have its own fuse. Some models of stoves have fuses within their own control panels too. Check your home's panel to see if a breaker has been flipped or a fuse blown, and follow up with the owners manual for your make and model of stove.

Microwave just stopped working while in the middle of cooking. clock and inside light went black - nothing works!


You could have over heated the microwave or blown a fuse due to a problem in the door circuit. Either way this can be repaired with minimal parts. I would suspect you blow the fuse to the cabinet due to temperature where to high in the unit. I would need a model number to assist you further..
Good Luck

Microwave won't heat up while in use


It sounds like the unit is in demo mode, they usually have a small d on the screen, try holding the "kitchen timer" pad down for 5 seconds, it should then work, if that doesnt apply to your model look in the trouble shooting guide of your owners manual, it will explain how to deactivate "demo" mode there...Phil

Kenmore microwave 721.80593402 died


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 you or someone you know wants to look into this, we have critical safety, disassembly, and troubleshooting info at our site, and our link is at our listing here on FixYa: http://tinyurl.com/yzjozk

You can probably find exploded views and order parts by entering your model number here: http://www.searspartsdirect.com

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.

KENMORE MICROWAVE (HOUSEHOLD) LOCKED


It sounds like you press STOP two or three times to lock it. Maybe that (or another key) will unlock it.

The lock / unlock procedure will be covered in your owner's manual.

Or you can try a hard reset - unplug it from the wall for one minute, then plug it back in and try again.

If you don't have your manual, you can get one here. (Enter your model number without any spaces)

Rack in microwave


You should not have any metals in the oven when the microwave is on. If you are just doing convection cooking, the metal rack should be in so that what you are cooking is raised up so the hot air can surround what you are cooking.
