COMPONENT TEST
J HOOD THERMAL CUT-OUT 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. A continuity check across the thermal cut-out terminals should indicate an open circuit unless the
temperature of the thermal cut-out reaches approximately 158½F(70½C) or more. At that temperature,
the contacts will close. The thermal cut-out opens automatically at approximately 104½F(40½C).
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
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 button 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 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.
Resistance between;
WHT(1) AND YLW (4) = 0Ω (Shorted)
BLU (2) AND YLW (4) = 34Ω
WHT(1) AND BLK (2) = 34Ω
RED(5) AND WHT(1) = 77Ω
RED(5) AND BLU (2) = 43Ω
YLW(4) AND RED (5) = 77Ω
