Touch control failed on GE Spacemaker Microwave HVM1540
First the numbers (used for cook time or quick cook) failed, but you could still cook using "Add 30 Seconds." Soon that failed as well, and now the touch control is totally dead. Bought this unit in March 2008, and it failed in June 2009, 3 months out of warranty. Will never buy GE again.

"F4" on a GE microwave means you have a failed humidity sensor.
You can get GE parts by searching by model number here.
If you have other questions, please contact me directly since FIxYa doesn't always inform us of follow-up questions.
I would need to know the full model number from the tag on it, and the FCC ID number can be helpful, too.

Microwave Oven Control Panel Repair Nationwide "Recycling by repairing since 1982"
Many models of the GE microwave have sensors that can detect humidity from the foods you are cooking. This allows the microwave to make adjustments to the power levels used to cook your food. If "Sensor Error" appears, you should either press "Clear" to cancel the mode or leave the food in the appliance longer to give the microwave more time to detect the food.
Press "Time Cook" to manually enter the time if you receive an error message when trying to use the "Sensor Reheat" mode of your GE microwave. The error message may be caused by the food item being too large or too small to detect.. good luck . please rate !
first thing I would suggest is a hard reset. Unplug the unit for a
minute or so. Then plug it back in, set the clock and try again.
If that doesn't work,
leave it unplugged for maybe an hour.
If it still doesn't seem to work, I'd consult the owner's manual for a quick refresher. You can find ithere.
If it still fails to cook at full power, I'd say your magnetron is failing.
And if so, to allow us to help you effectively (at no charge), please post a NEW problem to FixYa, and please
include your brand name and the full model number from the tag in or on
the unit, and your previous symptoms:
"I have a GE Spacemaker and used defrost for the first time at
Thanksgiving. Now I can't turn it back to normal cooking. Can you
please help me?"
More than likely the magnetron has failed. This could be for a number of reason. Do you use your microwave to heat wheat packs or warm plates? If so, you may have dried the magnetron out (they use the moisture in whatever you're cooking to heat it, and plates/wheat bags have no moisture).
I'd say a trip to your local Microwave repairer could be in order. It could also be the High Voltage Fuse which has failed. Either way a repairer will be able to tell you!
