Usually these happen when IO board is about to go. I have experience this . Clean the board and try to plug in wire connector back to the board. If it eke minarets or creates any new error code then you definitely need io board

F7: Thermocouple Open

CC Thermocouple

IR Thermocouple

1. Check the connection of open thermocouple on the I/O control board.

If the connection is OK, verify thermocouple is not an open circuit

by using your ohm meter. The cook cavity thermocouple should

measure approximately 4-5 ohms and the IR thermocouple should

measure approximately 30-40 ohms. Measure at the I/O control board

40-pin connector.

o Thermocouple indicates open circuit: Replace defective thermocouple.
o Thermocouple OK: Replace the I/O control board.

Its an easy fix although expencive for the parts. Just remove the rear blower cover then the six 1/4" nuts and it will come out.

it is because the switch kits are not setup properly.they need to set to open and shut in the right order,hope this helps regards lse

Hello. Interesting coincidence, but that error code is for the magnetron/microwave part of the toaster. You will need to have it serviced by someone familiar with the unit, it could be easy and reasonable, if just a fuse blew, but not likely. If the fuse blew, it is 20amps, so something took it out. Call turbo chef, they will get you to the closest servicer, may be able to help you on the phone.
