Hi rongoin,

This error occurred if you have a stuck function key on ERC. This can only be resolved if you will replace control board (also called ERC or clock). 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.

Hope this helps.

Thank you for using FixYa.

I have a Kenmore Elite Speedcook Microwave oven, model #665.63783600. What does error code F7 mean on this model?

F7 Error Code On Microwave Ovens With Inverter Board

An F7 error code could be an inverter board failure. Anything else that prevents microwave energy may also cause an F7 error, and must be checked. The technician should perform the following procedure to test for an F7 error code:

1. Check the magnetron.
2. Check the magnetron TCO (it should be closed).
3. Check the 3 interlock switches.
4. Check the harness wiring.
5. Check the electronic controls.
6. Check the inverter board.

For more free help, feel free to contact me via my site with your detailed symptoms and full model number and FCC ID number as shown on the tag in or on the oven.

Code f 7

There should be a "mini-manual" (tech sheet) hidden inside the unit behind the control panel or hidden on the left side behind the grille, which is very helpful when troubleshooting, testing, and locating components. It should cover an F7 error code.

A video is available here showing how to remove a typical over the range control panel assembly in under 5 minutes.

There is a technical sheet inside the unit.

On it you'll find help locating components and a chart which shows the "F" codes. F7 is likely either a door code or an inverter failure.

You can find helpful exploded view diagrams and order parts by entering your full model number from the tag on the oven here.

F7 ERROR CODE ON GH6177XPS

This is a known problem with this unit, and whirlpool has put out a Service Flash out on this. The reason this is happening is Electrical circuit interruption between the L1 and Neutral in the microwave invert circuit. This has to be addressed by a Tech.

Error F7

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.

F7 Error code on Kenmore Ultra Wave Microwave Hood Combination Model 665.61652100

The 665 the model number prefix means it's made by Whirlpool. F7 means it has a problem with the control board or keypad.

The first thing to try is a "hard reset". Unplug it from the power line for a minute, plug it back in, set the clock, then try again.

If it still has a problem, we repair these for customers nationwide with our guaranteed $39.95 service. If a new keypad were needed, that would add about $60 to the repair cost.

Please feel free to contact me directly if you need more help.

We're happy to help and we appreciate your thoughtful rating of our answer.

GH7208XR Error Code #7

Behind the right front corner faceplate is a bag with the tech support info.
I used this and went through all the troubleshooting and got to the power inverter board. This board has the 2 red wires out of it that go to the magnetron. Instead of replacing the whole inverter module , I examined all the components on it. I found that there are 2 high voltage rectifier diodes attached to the transformer and 1 of them was not testing good. The diodes are UXC2B diodes.. Just clipped out the bad one and soldered in a new one.
Hope this helps..
