There is a fuse blown, but I can't explain how to replace it. They are inside the unit. Good microwaves have many fuses and can be powered up, but have a blown element fuse.

During reheat and popcorn settings - the error code F4 appears

Hi hoodrd,
If you are encountering F4 error code from your Amana oven this is because you have an Open Oven Temperature Sensor. This error requires a replacement of new oven temperature. You may contact Sears for the replacement part at 1-800-252-1698; M-F 6:30 AM-10:30 PM - Sat 7:00 AM-9:30 PM - Sun 7:30 AM-9:30 PM - All times Central. Just get your model number ready when you call.
Hope this helps.
Thank you for using FixYa.

You have a defective gas sensor (humidity sensor).

There should 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.


At our Web site, we have a video available showing how to remove a typical over the range grille and/or control panel assembly in under 5 minutes.

You can find helpful exploded view diagrams and order parts by entering your full model number

Lost instructions. Can you provide uninstall instructions for JVM1190 under cupboard microwave? Thank you!

Many appliance owners manuals are available online as PDF files. There is usually no fee involved in downloading these.

Google your brand and model number. GE may have a website which has the manual available.

According to the owner's manual (which you can download free from us here),

1. Place the bag of popcorn over an upside-down 9" glass (or paper) plate.

2. Touch POPCORN pad.

It will cook and stop automatically.

If this does not work, you may have a bad humidity sensor or control board, etc. and parts for this model are generally no longer available.

Ge JVM1190 appears to be working but does not cook.

I spoke with a qualified microwave technician who advised me to buy a new microwave as the problem I was having indicated that the magnetron tube had blown. What a waste of time to ask for help from you.

The cooling fan is a must!

Otherwise, the magnetron will be ruined, and that drives up the repair cost.

If you or a friend decide to work on it, we have *critical* safety, disassembly, and troubleshooting info at our site, and our link is at our listing here on FixYa:

Magic chef microwave shuts down

We had the same problem with our brand new Magic Chef. Before going through the trouble of taking it back I called Home Depot. After talking to a Home Depot Rep I am told that the overheat sensor is under the glass plate directly beneath the popcorn bag. Popcorn gets very hot and the heat of the popcorn causes the sensor to shut the machine down. I would imagine this would be the same for a baked potato.
Very poor design.
I was told to put a microwave safe plate down and put the popcorn bag on it. This should help to reduce the heat and not trip the sensor.
A safety sensor is great, but not if it keeps tripping the machine and shutting down!
