F3 on a GE microwave indicates a defective keypad.

The keypad is a thin plastic membrane type that is glued to the plastic control panel frame.

If none or only some of the pads are working, there may be some foreign substance on the circuit board, the keypad connection, or inside the layers of the keypad, the latter of which cannot be repaired.

Trouble is sometimes due to spray cleaner being sprayed directly onto the keypad. Cleaner should be sprayed on the cloth first, then use the cloth to wipe the keypad clean.

Never use an ammonia-based cleaner on plastic as the ammonia can attack and crack it.

A handy person can remove the control panel frame and see if there's any liquid inside on or behind the panel. If so, it is possible to dry it out, but often that does not work.

Another thing is to unlpug the power at the mains for several seconds. Plug it back in and see if it works. A reset may do it.

At power-up, the display should flash or show a text message. If not, a key may be stuck due to a foreign substance or a defective keypad.

If certain keys are not working, there may be some foreign substance at the point where the green or blue plastic strip from the keypad plugs into the circuit board.

To check that, see our critical safety, disassembly, and troubleshooting info at our site. You'll find a link to our site in our

1. Be sure the oven is disconnected from the power line while you are taking it apart.

2. The keypad connection is the green or blue translucent plastic strip that plugs into a connector near the edge of the board.

3. There are two tiny tabs (one on each side) of the connector that you can gently pull up on to unlock the connector.

4. Then the keypad strip will lift out. Clean both sides of the end of the strip with a pencil eraser or alcohol-based cleaner if you like, but do not use ammonia-based cleaner. Dry the end of the strip.

5. Put the keypad strip back in, making sure both sides are down fully.

6. While holding the strip down, push the connector back down to lock it.

7. Try the keys again with the door closed.

SOURCE: Removal of GE Spacemaker Microwave oven

1. Unplug the microwave. The plug is probably in a receptacle that is in the cabinet above the microwave, or in the wall above the shelf that is above the microwave.

2. Remove the two (or three) screws that go straight down through the bottom of the cabinet, or the shelf, into the top of the microwave. Have help in holding the microwave when you do this, as the front of the microwave will be able to fall down when the screws are removed.

3. Allow the front of the microwave to rotate down a little, then lift the back of the unit up about 1/2" to 1". At this point, the microwave will be disconnected from the mounting plate on the wall, so you can move it forward and carry it away.

F-3 means shorted touch panel pad. In order to attempt clearing the code yourself, please follow the steps below:

  1. Press CLEAR/OFF or CANCEL.
  2. Program control again.
  3. If the fault code appears again, disconnect power to the microwave for 30 seconds.
  4. Program the cooking function again.
  5. IF it comes back up you should change out the panel hope that helps, good luck

Mmmm it's so easy,
First disconect the power, take the cover off, moslitly there would be 5 screws and two tab's on the top.
inside on the right hand side the magnetron it's a sylver box measuring about 4 in x 4 in x 5 in. It will have a plasic cover moslitly that would have to be remove first then on the magnetron there is 4 crews and one connector.
It should fall downard after.
If you have a power supply after the secondary , that may also be your problem.

Regards

Bob

I had the same problem. I removed the grill and opened the control panel as I read an answer from "GENE" on APP (Appliance Pros) that this indicated a short in the circuit board (TouchPad). I was going to replace the faulty circuit board but when I opened the control panel there it was......One wire harness had just came unplugged!! I plugged it in, reassembled and the microwave works again!

Why does my ge spacemaker jvm1740dd1cc no longer heats and the turntable does not work?


Bad door switch. Look for burnt terminals on one of the door switches. Replace the switch and cut off the burnt terminals and splice on new ones.

Hi jlariz,

The F3 error code on GE is about open or shorted oven temperature sensor (RTD. You have to check sensor harness and harness connection between oven sensor and oven control.

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.

GE Spacemaker microwave oven - Sensor error


Hello :

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 .

Not hot


In all likelihood the mangnetron has failed, or perhaps even the Power Supply. or a fault that is shutting the system down for safety reasons You need to have it serviced by a reputable service centre/man. Ensure you get a firm "Quote" before proceeding, and remember these days the cost of repair can equal or exceed the price of a new one.

Spacemaker beeping loud and f3 message driving us crazy


The error code F3 indicates an oven sensor problem. The oven sensor is most likely the failed part. The oven sensor probe must have the correct resistance readings at specific temperatures. When the electronic range control (ERC) cannot identify the correct resistance of the oven sensor or the resistance is way out of specs F3 will display.
I recommend calling a service technician to diagnose and repair your oven.
