Question about GE Spacemaker JVM1640SJ Microwave Oven

1 Answer

Express cook doesn't heat. Time cook seems to work at least sometimes

Everything works normally, except food doesn't heat when using express cook. If I use time cook and select a power level, it does seem to heat OK, though maybe not quite as fast as usual.

    Thank you so much - the hard reset seems to have solved the problem. I also viewed your video in case I needed to do the other steps you suggested, but (fingers crossed) just unplugging it seems to have cured the problem. Wow - I was about to buy a new microwave since this one is 9 years old. Thanks for your assistance! Sally M

    Thefirst thing I would suggest is a hard reset. Unplug the unit for aminute or so. Then plug it back in, set the clock and try again.

    On some models, there is an extra winding in the high voltage transformer and it has its own fuse. I'm wondering if that might be the problem here...

    Have you looked at the "mini-manual" hidden behind thecontrol panel or hidden on the left side behind the grille?

    Atour site, we now have a video available showing how to remove a typicalover the range control panel assembly in under 5 minutes.

    If you would want to scan and e-mail or copy and fax the "schematic diagram" page of the mini-manual (or the entire document), I would be happy to help you further.

    Feel free to contact me directly for more information & help.

    We're happy to help you with free advice and we'd appreciate your thoughtful rating of our answer.

How can I get my microwave to actually heat when everything else (cook time, power level, clock, etc., are set and seem to be running?


Sounds like the MW Emitter is not working or the wave guide is disconnected. If it is the wave guide then you can fix it yourself if you take the rear cover off. It is the pipe, which in cross section is quite rectangle shaped with rounded corners. It should be connected to the emitter at one end and the opaque guide cover at the other with no breaks. If the emitter is faulty then seek professional help.

New microwave stopped working after 15 seconds


Possibly the fuse / breaker is tripped, usually all outlets in one room share same breaker. Check breakers (or fuses) or try outlet in differnt room. If the outlet has power, (plugin a lamp to check) and the microwave still does not work, take it back to store for replacement or refund.

Maytag microwave problem everything seemingly works but does not heat. Help


see this causes and fix it. God bless you
Diode The high voltage diode converts the A/C power output of the transformer to D/C, doubling the voltage to nearly 5,000 volts. This high voltage powers the magnetron which emits the energy that cooks the food. If the diode burns out, a lower A/C voltage reaches the magnetron, which is not sufficient to power the magnetron. When the diode fails it is often visibly burned out. If it appears to be good, it can be tested with a volt-Ohm meter capable of testing diodes. High voltage diodes frequently fail and are one of the most common points of failure in a microwave oven.

Door Switch If the microwave does not heat, one of the door switches might be defective. Microwave ovens normally have three door switches, if any of them fail the microwave does not turn on and does not heat. Check the switches for continuity with an Ohm meter.

Magnetron If the microwave oven doesn't heat the magnetron tube might have burned out. The magnetron uses high voltage, high current DC power to generate the microwave frequency that cooks the food. If the microwave oven is turned on when it is empty this can cause the magnetron to burn out. Once it is burned out it has to be replaced, it's not repairable.

High Voltage Capacitor If the microwave doesn't heat the high voltage capacitor might be defective. The high voltage capacitor works with the high voltage diode to convert the output of the transformer to DC voltage and to double the output voltage. If the capacitor is burned out the entire high voltage circuit stops working properly. The high voltage capacitor can be checked with a special VOM meter which has a capacitance testing capability. Be aware that the high voltage capacitor can retain a charge of more than 3,000 volts and can injure or kill a person if not handled properly. Only trained technicians should perform this type of testing.

High Voltage Transformer If the microwave does not heat, the high voltage transformer might be burned out. Microwave ovens produce a very high voltage in order to power the magnetron antenna, which emits the energy that cooks the food.

Thermal Fuse If the microwave doesn't heat the thermal fuse may have blown. It can be tested for continuity. Watch our fuse testing video for more information.
Thermoprotector If the microwave doesn't heat the thermoprotector may have tripped. This is a safety device to prevent the microwave from overheating. It can be tested for continuity to see if it's blown.

Main Control Board If the microwave doesn't heat the main control board may be defective. This is not common. When a microwave doesn't heat the problem is usually within the high voltage circuit; either the high voltage capacitor, diode, transformer or magnetron.

Emerson microwave not working 900 watts


The Emerson MW8999SB 0.9 cu. ft. 900 watt Microwave Oven is relatively compact, and certainly inexpensive, but doesn't skimp on functionality. We were surprised at all the options you get with this little microwave. It's only 20 inches wide, 11.3 inches high and 16.1 inches deep yet. The interior can still accommodate a regular size dinner plate or small (10-inch-square or round) casserole. Plus, there are 10 power levels, eight one-touch function buttons, six Express Cook settings, timed and automatic defrost options, and a rotating glass turntable to circulate the food for more even cooking.

We were very pleased with the performance of the Emerson MW8999SB. It did a fine job heating water for tea, cooking a couple of baked potatoes, reheating leftovers and steaming fresh vegetables. Even the automatic defrost proved surprisingly efficient, letting you enter the weight of the item(s) to be defrosted (4-100 ounces) for easy operation. Chicken breasts were almost fully defrosted after one cycle. We needed to stop and separate the food pieces to finish the defrost cycle.

The unit is styled mainly in black but has stainless steel trim around the door and control panel. The smooth touchpad control panel is attractive and easy to wipe clean. We loved the one-touch Express Cook buttons, which let you activate the unit at 100 percent power for 1-6 minutes, by pressing the corresponding number pad. We also appreciated extra touches such as the Start/+30 sec. button, which can be used to start the oven or add an extra 30 seconds each time it is depressed.

It's hard to go wrong when the functions are so simple. The only tricky part was identifying certain codes used on the display screen. When changing the power level, for instance, PL10 is displayed on the screen. Pressing the button additional times lets you toggle through the different levels. Likewise, the Auto Cook settings may need to be pressed multiple times to obtain the correct weight or portion for the food being cooked.

We were amazed that a machine costing so little also offered two-stage cooking, which lets you start cooking (or defrosting) on one setting and finish on another. All in all, the Emerson MW8999SB is an excellent value.


Pros: Touchpad controls, eight one-touch function buttons, six Express Cook settings, two-stage coking option
Cons: Limited interior capacity can only accommodate dishes up to 10 inches, no sensor

Everything works but food does not heat up I have a ge over the range microwave


If everything seems to work, except cooking the food it is probably the magnetron which sells for $100-$150 for the part alone.

Have GE JVM2050 over the range microwave, which stopped heating food and water since this morning. All other functions including light, key pad, clock, turntable work normal. The magnetron sound also


if everything works except the heating, it is most likely the mag tube is on its way out.........that is the most common reason for it not too cook.......since the microwave is a GE and it is 3.5 years old, i would say you are better off buying a new microwave, the mag tube starts at around $70.00 and up + the labor it costs too have a service person put it in........around another $60.00

Everything works...Except for actually heating the food


It has a bad magnetron. This is the tube that provides the microwaves to heat the food. Not too easy to replace yourself but it can be done. Cost of magnetron is probably less than $50 or $60.
