On a GE, F3 means that you have a shorted pad on the keypad.

This is not too hard a job for a do-it-yourselfer, but if you'd like, we do this job for $39.95 plus parts nationwide.

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 ourlisting here on FixYa: http://tinyurl.com/yzjozk

There is also a very helpful "mini-manual" hidden inside the unit behind the control panel. It's very helpful when troubleshooting.

From looking at the owner's manual, it looks like the vent fan is only supposed to come on when the internal temperature of the microwave gets too high OR when you press the VENT FAN pad. Here are a couple of fan-related excerpts from the owner's manual, which can be found here: http://products.geappliances.com/ProdContent/Dispatcher?REQUEST=SKUOBJECTS&DOCUMENT=Use%20and%20Care%20Manual&SKU=JVM1840BD (or the better URL here: http://tinyurl.com/yn7r6g) Automatic Fan An automatic fan feature protects the microwave from too much heat rising from the cooktop below it. It automatically turns on if it senses too much heat. If you have turned the fan on, you may find that you cannot turn it off. The fan will automatically turn off when the internal parts are cool. It may stay on for 30 minutes or more after the cooktop and microwave controls are turned off. - Vent Fan The vent fan removes steam and other vapors from surface cooking. Press VENT FAN once for high fan speed, twice for medium fan speed, a third time for low faw speed, or a fourth time to turn the fan off. Press the VENT FAN BOOST pad for extra fan speed. - Hope this helps.

The problem with your Display of your GE Microwave/Speedcooker is not the Digitron WB27X10856 display board? The flickering and ultimately failure over of the display is due to the WB27X10861 GE microwave control board which is a rebranded (LG 6871W1A417/6871W1A417A board) which GE then sells as a markup. The princple purpose of this board is to convert (i.e. rectify) AC to DC at various voltage levels needed by the rest of the microwave to run their control circuits in the microwave. A portion of the GE microwave is always on so the AC/DC supplly is always on. Overtime the electrolytic capacitors in a section of the board fail or degrade to a point they the DC suppy starts to produce ripples in the DC power supply which results in circuit board failures. These ripples produce deep spikes of voltage of 120 Hz that the other circuits are sensitive too. I just exmined a failed WB27X10861 board and measued the capacitance of each of the seven electroylic capacitors. Of the 7 capacitors, 2 had failed over time. The others 5 have degraded 10 to 15 percent but still within their design spec. The two that failed, C07 - 1000uF 25 V had a measured value of 207uF and the other C08 - 220uF had a measured value of 13uF. There was no visible bloating on either SAMWHA SG capacitor. Nomally, these capacitors are rated at 2000 hour at 85 degree C. 2000 hr is only 83 days, but since the voltage is less and the temperature is probably 40 to 50 degrees inside the capacitor these capacitors may last 10 years. They harder they work the shorter the lifespan. There are two solutions, either purchase a new replacement control board or replace the failed C07 and C08 capacitors within the failed board with better ones. You can easily buy 10,000 hour , 105 degree C rated capacitors for probably 25 cents more than 2,000 hour capacitor. Most people don't have the resouces to repair a board so buying a new board is their only solution. Don't buy a used board on ebay because a used board is probably on the verge of failure.

Take model # to searspartsdirect.com. They typically have manuals in parts listings.

You have a direct short to ground. https://www.fixya.com/support/r29874712-repairing_microwave_ovens ..

No, because it is an Air Fryer and Broiler as well. It would generate too much heat and no where for it it escape. You would need to use it on a counter as described or buy an over the range model.

No Microwave Oven are just too dangerous. The switches and interlocks have to be correctly aligned for safety. Plus the inside has heart stopping voltage waiting to jump to anyone with a half inch away! https://www.fixya.com/support/r29874712-repairing_microwave_ovens ..

I would not risk it. Your better finding out why there is a burn mark there. The plastic film with the burn mark will be a specific one for microwave ovens. Basic peel and stick plastics could be the wrong type and it could also melt when the microwave gets hot.

I GOT the same issues. Can some one help?

That issue sounds like it it likely to be the control board, or maybe a bad connection to it or a dry joint. https://www.fixya.com/support/r29874712-repairing_microwave_ovens ..

it should lift out once you it tilted. page 5 this not your exact model, but they are mounted the same way https://documents.designerappliances.com/Installation-Instructions-JXA019K.pdf

Ck here.... https://www.appliancepartspros.com/repair-help/general-electric-microwave-pvm1790sr1ss-repair/pvm1790sr1ss-wont-start.html But before throwing parts at it give them a call #877#. I'm NOT affilated with them. Best to you.

Hello, friend! It is noteworthy that if the GE Spacemaker microwave model JVM240BL001 is displaying "Enter NORM SOUND 2" on the digital display, it indicates that the microwave is in the programming mode for adjusting the sound level. To exit this mode and return to normal operation, you can try the following steps:

1. Press the "Clear" or "Cancel" button. This should clear the programming mode and bring the microwave back to its normal state.
2. If pressing the "Clear" or "Cancel" button doesn't work, you can try unplugging the microwave from the power outlet for about a minute. Then plug it back in and see if it resets the display.
3. If the issue persists, consult the user manual for your specific model. The manual may provide additional instructions or troubleshooting steps to resolve the issue.
