Component Test
HOOD THERMOSTAT TEST
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. (See Warnings and Instructions on page 3-1)
4. A continuity check across the thermal cut-out terminals should indicate an open circuit
unless temperature of 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.
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. (See Warnings and Instructions on page 3-1)
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.
BLOWN MONITOR FUSE 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. If motor does not turn, touch 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 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 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.
