When you put something in microwave and push for time it will run for about 5 seconds and fan will change tone and it won't heat anything



4 Perform a hard reset. Pull the plug out of the wall power supply, and wait a moment. Plug the GE microwave back into the wall power supply to reset any anomalies with the microwave's memory. You will need to reset the time of day if you perform a hard reset.
5 Reset the time of day. Press the "Clock" button, and turn the dial to set the hours. Press the dial to enter. Follow the same procedure for the minutes and a.m. or p.m. Press the "Start" button to start the clock.

I have a GE spacemaker XL 1800 microwave oven made in April, 2004. The Serial number is GG902192 B and the MN is HDM1853FJ02. It appears to work correctly, (it gets electricity and so forth,) but just...

The magnetron may have either failed or is not being supplied with the extremely high voltage required to run it.
Make sure the !!!!capacitor is discharged!!!!! before attempting any sort of repair.
Check the door interlock switches first then the high voltage diode with either an AVO model 8 on high resistance range for short circuit, the feed fuse on the primary of the high voltage transformer and then finally, the magnetron is best checked by substitution.
Hope that helps.

My old GE oven (JSP38G052BG) won't bake or broil. It start then stop after 1 or 2 minutes. The heating elements get worm. Can you help me please

Hello ediben11.

If your oven's bake or the broiler heating elements won't heat but the range burners still work;the clock may be set for a timed or self-cleaning cycle. So,make sure to check the clock buttons and the knobs are set properly.
*If your clock has a knob that says "push for manual" then push the knob in after that, try the baking and broiling elements again.

*If it still does not work properly, you may have a defect in the thermostat/selector switch/common wiring.

*If the oven does not have a separate bake or broil selector switch; then the thermostat is probably the problem. It is not easy to check the selector switch or thermostat for proper operation. If you suspect a problem in this area, call a qualified appliance repair technician.

Hope this helps.

Can set time and all features but when we push start nothing happens. Does not heat and does not rotate.

this sounds like the power supply and or the magnetron has become faulty we get this all the time in the shop. You need to get a "Quote" from a competent repair shop.

Not hot

In all likelihood the mangnetron has failed, or perhaps even the Power Supply. or a fault that is shutting the system down for safety reasons You need to have it serviced by a reputable service centre/man. Ensure you get a firm "Quote" before proceeding, and remember these days the cost of repair can equal or exceed the price of a new one.

GE Microwave JE1640 power went out, then came on later with ''reset'' message on display. What does that indicate?

The "RESET" indicates that there was a power failure. You should be able to push the clear/reset button and then set the clock and be on your way.......

I have Emerson Microwave #mw8999sv which has the Express Cook option- cooking 1 - 6 minutes. How do I cook for 1 minute 30 seconds, etc.? Thank you.

The owner's manual is here. On page 10 we find:

1. Press the POWER button; the Microwave and High
Cook indicators will light and “PL 10” will light in the
2. Press the POWER button different times to set the
desired power; the display will show the percentage
you chose. If selecting power level 70%-10%, the
Low Cook indicator will light instead of the High
Cook indicator.
3. Press number keys to set the desired cooking time.
4. Press the START/+30SEC. button to start cooking;
the Microwave and one of the Cook indicators will
blink and the display will countdown the remaining
cooking time in minutes and seconds. It will beep
five times when cooking is completed.

No power

To enter the time you must push the clock button once before you enter the time and again after you enter the numbers. Try that and you should be all set.

Please mark this as a fixya! thanks.
