20 Most Recent GE JVM1640 Microwave Oven Questions & Answers

When you stated no power that there are no lights or fans that can be made to operate, yet fuse checks good. On some units, the fuseholder will be mounted to a small pc board. Remove the screw that secures this board and inspect the underside for bad connections. What happens is power enters board through power cord but power is not provided to rest of oven.

Yes, you can change the latch in the door

You should be able to buy only the door handle and avoid having to replace the entire door. Appliancepartspros.com carries the handle. Just type in the model number you provided and look for item #3 under the parts listing. The part number and price varies based on the color you need. Make sure you order the correct color. To access the door handle mounting screws on MOST microwave ovens, you have to remove the inner door panel that goes around the perimeter of the glass. You can use a small screwdriver to carefully pry the plastic up and work your way slowly around the perimiter of the glass. Most microwave ovens also have grooves in the panel that you can insert the screwdriver into. Use care not to pry against the glass. The glass is tempered and also has an RF shield that prevents harmful microwaves from potentially harming the consumer. If you break the glass, you will need to purchase a new door.

The door handle screws are located behind the inner panel. Simply remove the broken handle and install the new one. Re-insert the inner door panel carefully and gradually work your way around the perimeter of the door glass and make sure it snaps back into place.

If you have questions, please let me know. I hope you find this information helpful.

I suggest you have the microwave oven replaced, the prices have dropped considerably for the last several years and you have got your money worth out of the unit.

Hi

F3/F4 error in your GE microwave means that the keypad/touchpad is bad and should be replaced. However, before replacing it you can follow these step by step instructions to clean the touchpad assembly and see if it works:

1) Unplug microwave
2) Remove two small screws from upper face plate
3) Remove screw on upper side of control panel
4) Life panel and pull out
5) Identify flat tape-like harness connecting circuit card to keypad
6) Wipe down harness with an all-purpose wipe
7) Use hairdryer to dry remaining leftover moisture

8) After this put the keypad back if its not solved then replace it.

Hope this helps...please post back for further assistance.

BAD CONTROL BORD OR BAD TRANFORMER ,IF THIS MICROWAVE IS LESS THEN A YEAR PROBLEM CAN BE COVER FROM FACTORY WARRANTY. IF NOT CALL SEARS TO GET YOU STIMATION FOR REPAIR..1800-4MY-HOME..

It sounds like the magnetron may have either failed or is not being supplied with the extremely high voltage required to run it.

YOUR SAFETY IS PARRAMOUNT

This is a job for a professional but if you are safety clued up, here's instruction.
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 or moving coil meter on high resistance range for short circuit, (DVM's won't show the fault!), the capacitor can fail and go 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.
