Getting error code F7 - GE Ovens

Microwave will not operate (cook). F7 error code appears on the display. Electrical circuit interruption between L1 and Neutral in the microwave inverter circuit.

Possible reasons:
1. Check door, hinge and cavity front alignment and adjust as needed.
2. Check the operation of all interlock switches.
3. Check over temperature protector for the magnatron.
4. Check all Cavity Thermostats for closed circuit.
5. Unplug the oven for at least 40 seconds. If this solves the problem
A. Check the Cooling Fan for proper operation or blockage
B. Check the resistance of the magnetron thermostat. It should be 0 Ohms, replace if necessary.
6. Check that the control cable to the 1100 watt inverter is properly connected to plug P2 on the display PCB & Adjust or Reconnect
7. If interlock switches operate correctly, replace 1100W inverter.
8. If problem persists, replace control assembly.

Hi,one of the most common problems with GE electric built in ovens is the error code "F7′ shown on the display. I've seen it many times before and today I had a service call for the same problem again. The error code "F7" will be displayed along with a beeping sound if the ERC (Electronic Range Control) or "clock" senses one or more buttons on the control panel stuck. It could be displayed in any mode: "cook", "clean" or even more often in the "time of the day" mode. In order to fix it, the control panel has to be replaced. This is a very simple job and you will need just a 1/4′ nut driver and a Phillips screwdriver.

To get the right replacement part just click on the link http://www.appliancepartspros.com/ then type the model number of your oven (it is located at the bottom left corner on the door frame of the lower oven) in the search box, click on the "search" button and in the new window type the word "control panel" in the "search by keyword" box and click the "search" button.
Always turn off the circuit breaker first.
Open the oven door (if you have a double oven, it should be the upper one) and remove three screws (on some models just two on corners) from the bottom of the control panel. If the control panel on your oven is made of stainless steel, then you have to pull the oven out of the cabinet for about 2′ to 3′ to get better access. Pull the control panel forward and up to remove the tabs on the top of the frame, out of the holes in the end caps. Pull the control panel out and turn it about 90° toward yourself (the face of the control panel down). Unplug the control panel ribbon from the ERC. Remove four screws holding the ERC to the control panel. On some models you also have to remove the screw which attaches the ground wire to the control panel. Let the ERC hang on its wires, remove the old control panel and replace it with the new one. On some models before you do it, you have to remove the end caps and the bottom shield from the old control panel and install them on the new one. Do not forget to plug the new control panel ribbon into the ERS slot. Attach the new control panel to the oven and turn the circuit breaker on. Set the time of the day and you are back in business.
