4.  Check voltage between either side of the Bottom 

TCO and Relay Board CN6 pin 9. 

• If 120 VAC is present, problem is with 

Magnetron Fan Motor or wiring to motor. 
(See 

Wiring Diagram

.)

• If 120 VAC is not present, the magnetron 

fan motor relay on the Relay Board is not 
closing. (See

,

 troubleshooting 

section.)

Disassembly. 

(See 

Magnetron Fan Assembly

.)

Note:

 

•  In the following step, 2 screw access holes have 

been provided in the back of the oven to remove 
2 fan cover screws.

•  Use a magnetic Phillips-head screwdriver             

(recommended).

3.  Remove and capture the 2 Phillips-head screws 

that attach the bottom of the fan cover to the 
air guide.
