Troubleshooting
1. Disconnect power to the oven.
2. Pivot the Control Panel Assembly out from the
oven. (See
Control Panel Removal
.)
3. To gain better access to components, remove
the wires that plug into the large relays on the
Relay Board.
(See
Relay Board
.)
Cut the wire tie
that the Smart Board CN103 wire harness (See
Smart Board
.) is routed through.
4. If high speed fan is not working, go to step 8.
5. If medium speed fan is not working, go to step 9.
6. If low speed fan is not working, go to step 10.
7. If the motor hums in all speeds, go to step 11.
8. Set ventilation fan to high, check voltage
between either side of the Bottom TCO and
Relay Board CN16 pin 1.
• If 120 VAC is present, problem is with
Ventilation Motor, or wiring to motor.
• If 120 VAC is not present, the ventilation fan
high relay on the Relay Board is not closing.
(See
Relay Board
, troubleshooting section.)
9. Set ventilation fan to medium, check voltage
between either side of the Bottom TCO and
Relay Board CN16 pin 3.
• If 120 VAC is present, problem is with
Ventilation Motor or wiring to motor. (See
Wiring Diagram
.)
• If 120 VAC is not present, the ventilation fan
medium relay on the Relay Board is not
closing. (See
Relay Board
, troubleshooting
section
.)
10. Check voltage between either side of the Bottom
TCO and Relay Board CN16 pin 5.
• If 120 VAC is present, problem is with
Ventilation Motor or wiring to motor. (See
Wiring Diagram
.)
• If 120 VAC is not present, the ventilation fan
low relay on the Relay Board is not closing.
(See
Relay Board
, troubleshooting section.)
11. Rotate the fan blade by hand, if it does not
rotate freely, check for obstructions in the blade.
If clear, replace Ventilation Motor.
