HI. This code represents a short in the key pad that is part of the electronic control board. Some units will incorporate the key/touch pad, and the main control board as one whole device. If this is the case, simply replace the entire (ERC). If the unit is equipped with a separate key/touch pad, and it is linked to the main control board, via ribbon cable, simply replace the key/touch pad.

F7- Shorted key/touch pad.

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.

Microwave runs but will not heat error msg.F7 whats the problem cost to repair.


F7 refers to a bad inverter board but some times can be the magnatron the process for testing way to complicated plus it requires special needle point test leads usually just change both since you have to drop unit to change either one pricey usually over 200 for inverter mag ranges 150-250 depending on model maybe cheaper to replace MW

How CAN i TEST MY MICROWAVE?


Most common cause of an F7 code on these models is a bad inverter or magnetron. Generally it is best to replace both the magnetron and the 1100 watt inverter board at the same time, since a bad magnetron is usually what burns out the inverter board.

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.

The oven (10+ years old GE True Temp double wall oven) beeps and displays an F7 error message. We can temporarily stop it by pushing the Clear button, but it starts again in a few seconds. We don't know...


I'm a GE tech, the F7 means there is either a stuck button on the keypad or relay on the board behind the keypad. Shut off the breaker. Remove the 3 screws under the keypad and lift the panel a bit to remove it. Lay it face down on the top rack and disconnect the ribbon cable. Turn power back on and if f7 goes away the problem is in the keypad. If f76 returns it's in the control. We typically replace both together because usually if you replace 1 it will come back later then be the other part.

You have a faulty keypad. You could probably special order this part from a local appliance parts supply store for 50-60$ or purchase a new microwave.

Touch pad doesn't work


ut the tech sheet did mention that intermittent F7 problems are usually caused by poor connections. So I pulled the ribbon connector off the control board and cleaned the copper connectors using a pink pencil eraser. That whupped that puppy! But then I went out on another service call, same oven, different house. The pink pencil eraser trick didn't work on this one so I had to apply some of that famous Samurai gray matter. To identify the problem on this one, I cut power to the range and disconnected the ribbon connector that connected the touch pad to the electronic range control (ERC) board. Then I re-applied power and let it sit that way for 24 hours after which the customer was instructed to call me and report on the error code status of the oven. If no error code was reported, I knew the touch pad was the problem. If, on the other hand, the F7 error code came back, then I knew the (ERC) was the culprit. In this case, the error code did not come back during the test period and, using my keen, Vulcan-like powers of deduction, concluded that the touch pad was defective. I replaced the touch pad and problem solved!
