Quite often this is due to grease or food particles stuck to the inside of the oven or stuck on or behind the waveguide cover.

The waveguide cover is usually about the size of a playing card and often held in place by a plastic rivet.

In some models it is the plastic ceiling.

It can be fragile, and the metal edges of the oven behind it can be sharp, so be careful!

The cover and the metal behind it should be cleaned with a mild, non-ammonia cleaner.

If the cavity metal of the oven is chipped or charred, it will have to be sanded smooth and clean and dried thoroughly.

Then you can apply some high-temperature appliance paint, available from places like Wal-Mart, Lowe's or Builder's Square.

If your waveguide cover is burned, it will need to be replaced.

Please reply back with more details if you need further help.

JES1290SK No power when on. Display works, work light works until enter is pushed. No motor movement


Does the convection work? If so likely you need a magnetron If the control panel is having problems then it needs to be repaired or replaced. It could be just a stuck relay inside so a firm hit may release it

JES1290SK No motor or inside light when turned on. Display works. Light works until turning on unit.


please see the steps and fix it. God bless you
  1. Inspect the power cord Unplug the power cord and check for voltage at the outlet. Also inspect for damage, shorts, or burn marks that can be a possible safety hazard.
  2. Bad door switch If your microwave does not work at all and you know everything is plugged in properly and the outlet is functioning, then also check the door hooks and the door release button. Using a volt-ohm meter on RX1, check your terminals. When your microwave door is closed you should have a reading of zero. Once the door is open the reading should change to infinity. If these readings do not match up, replacement of the door switch is necessary.
  3. Blown fuses To determine if your fuse has blown out, which may attribute to your microwave not running, you need to pull the fuse out using a pair of fuse pullers. Lay it down and using a volt-ohm meter on RX1, check both ends of the fuse in question. If you do not get a reading of zero, then you will need to replace the fuse.
  4. Bad fan motor Locate the fan and remove the leads. Again using the volt-ohm meter on RX1, check the terminals. If an infinity reading is displayed, it means that the fan has gone bad and requires replacement.

Quite often this is due to grease or food particles stuck to the inside of the oven or stuck on or behind the mica waveguide cover.

The waveguide cover is usually about the size of a playing card and often held in place by a plastic rivet.

Sometimes it is the ceiling of the oven.

Your owner's manual may address this. You can download GE owner's manuals and installation instructions here.

It can be fragile, and the metal edges of the oven behind it can be sharp, so be careful!

The cover and the metal behind it should be cleaned with a mild, non-ammonia cleaner.

If the cavity metal of the oven is chipped or charred, it will have to be sanded smooth and clean.

Then you can apply some high-temperature appliance paint, available from places like Wal-Mart or Lowe's.

If your waveguide cover is burned, it will need to be replaced.

Sparks ae flying in my microwave


GE in essence says it is unrepareable and insafe. I suggest that would be saying it is trash.I don't know what that carboard is, possibly indulation? Ot may have /be a a oiece oce of laminated metal like some paper plates have..Not replaceable is a poor answer. Call them back and make a fuss. If it's not too far over warranty, they may work with you to shut you up.. oops, sorry, to pacify you.
:-) Good luck.

hi my name is mark, most microwaves have fuses in them. if you are comfortable taking things apart you can fix it. you will need hand tools, a meter to check the fuse. radio shack sells inexpenive ones. unplug the microwave when you disassemble oven. first make sure the circuit breaker to the oven is not tripped. hope this helps. thank for your question.

I can't get my clock set. I push options, 3 and 1, then when I put in the time, nothing happens. I need to know if I can use a ceramic turntable out of my old Microwave Convection oven. My oven...


In case your owner's manual is missing, you can download it here.

If you're still having trouble after consulting the manual, please reply back.

The ceramic turntable (actually ceramic coated metal) will be fine as long as it doesn't have chips or cracks where arcs can occur.

Also, for even heating and longer turntable life, don't place your food in the center, but slightly off-center instead.

If you need to order a new turntable, enter your full model number JES1290SK here http://tinyurl.com/gv383
