PROCEDURE
LETTER
J HOOD THERMAL CUT-OUT TEST
. 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 40½F(60½C) or more. At that temperature,
the contacts will close. The thermal cut-out opens automatically at approximately 3½F(45½C).
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.
K HOOD FAN MOTOR TEST
. 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 button once and check voltage between pins "" and "2"
(Blue and Black wires) of the 6 pin connector. If 20 Volts appear and the hood capacitor is good,
replace the hood fan assembly. If 20 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.
