Component Test
HOOD THERMOSTAT TEST
1. Disconnect the power supply cord, and then remove outer case.
2. Open the door and block it open.
3. Discharge high voltage capacitor. (See Warnings and Instructions on page 3-1)
4. A continuity check across the thermal cut-out terminals should indicate an open circuit unless
the temperature of the thermal cut-out reaches approximately 140°F (60°C) or more. At that
temperature, the contacts will close. The thermal cut-out opens automatically at approximately
113°F (45°C).
5. Reconnect all leads removed from components during testing.
6. Reinstall the outer case (cabinet).
7. Reconnect the power supply cord after the outer case is installed.
8. Run the oven and check all functions.
HOOD FAN MOTOR TEST
1. Disconnect power supply cord, and remove outer case.
2. Open the door and block it open.
3. Discharge high voltage capacitor. (See Warnings and Instructions on page 3-1)
4. If the motor does not turn, touch the FAN pad once and check voltage between pins “1” and
“2” (Blue and Black wires) of the 6 pin connector. If 120 Volts appear and the hood capacitor
is good, replace the hood fan assembly. If 120 Volts does not appear, check the motor circuit.
The resistance values of motor terminals are shown below:
5. Reconnect all leads removed from components during testing.
6. Reinstall the outer case (cabinet).
7. Reconnect power supply cord after the outer case is installed.
8. Run oven and check all functions.
