Component Test
HOOD THERMOSTAT TEST
1. THERMOSTAT (60°C ON)
1. Disconnect the power supply cord, and then remove outer case.
2. Open the door and block it open.
3. Discharge high voltage capacitor.
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.
2. THERMOSTAT (70°C OFF)
1. Disconnect the power supply cord, and then remove outer case.
2. Open the door and block it open.
3. Discharge high voltage capacitor.
4. A continuity check across the thermal cut-out terminals should indicate an closed circuit
unless the temperature of the thermal cut-out reaches approximately 158°F(70°C) or more.
At that temperature, the contacts will open. The thermal cut-out closes automatically at
approximately 131°F(55°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 the power supply cord, and then remove outer case.
2. Open the door and block it open.
3. Discharge high voltage capacitor.
4. If the motor does not turn, touch the FAN HI/MID/LO pad once (set hood fan motor power
“HIGH”) and check voltage between pins “1” and “2” (Blue and Black wires) of the 6 pin con-
nector. 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 as follows:
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.
