TEST PROCEDURES
PROCEDURE
LETTER
COMPONENT TEST
with the door opened (in this condition the plunger of the monitor switch is pushed in), the meter should indicate an open circuit. If improper operation is indicated, the switch may be defective. After testing the monitor switch, reconnect the wire lead to the monitor switch (COM) terminal and check the continuity of the monitor circuit.
5.Reconnect all leads removed from components during testing.
6.Reinstall the outer case (cabinet).
7. | Reconnect the power supply cord after | Black | White/White |
| the outer case is installed. |

8. | Run the oven and check all functions. |

IBLOWN 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.
4.If the monitor fuse is blown when the door is opened, check the primary interlock relay, secondary interlock switch and monitor switch according to the "TEST PROCEDURE" for those switches before replacing the blown monitor fuse.
CAUTION: BEFORE REPLACING A BLOWN MONITOR FUSE, TEST THE PRIMARY INTERLOCK RELAY, SECONDARY INTERLOCK SWITCH, DOOR SENSING SWITCH AND MONITOR SWITCH FOR PROPER OPERATION.
If the monitor fuse is blown by improper switch operation, the monitor fuse and monitor switch must be replaced with "monitor fuse and monitor switch assembly" part number
5.Reconnect all leads removed from components during testing.
6.
7.Reconnect the power supply cord after the outer case is installed.
8.Run the oven and check all functions.
JHOOD 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
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.
KHOOD 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 / 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:
