SOURCE: what is a F7 code on the display mean
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.
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.
At
our Web site, we have a video
available showing how to remove a typical
over the range control panel assembly in under 5 minutes.
If you don't find yours,
or if you want to look at it without disassembling the oven, you can
download it here.
You can find links to helpful exploded view diagrams and part ordering help here.
I recommend that you bookmark that link to your favorites.
We're
happy to help you with free advice and we'd appreciate your thoughtful
