INVERTER UNIT TEST
WARNING: DO NOT TOUCH THE COMPONENTS OF THE INVERTER UNIT WHILE
INVERTER UNIT IS ENERGIZED. IT IS DANGEROUS BECAUSE THIS HAS
HIGH VOLTAGE COMPONENTS.
CAUTION: Do not operate inverter unit by itself .
CAUTION: Do not connect the oven to wall outlet without the outer case installed.
Before checking the inverter unit, carry out the following 4 steps.
1.
Disconnect the power supply cord, and then remove outer case.
2. Open the door and block it open.
3. Make sure that the wire leads and the connectors are connected correctly to the inverter
unit, control unit and magnetron.
Chart for checking the defective inverter unit:
OVEN THERMAL CUT-OUT TEST
1. Disconnect the power supply cord, and then remove outer case.
2. Open the door and block it open.
3. A continuity check across the thermal cut-out terminals should indicate a closed circuit
unless the temperature of the thermal cut-out reaches approximately 293F(145C).
An open thermal cut-out indicates overheating of the oven, exchange the oven thermal
cut-out and check inside of oven cavity and for improper setting of cooking time or
operation of control unit. Check for restricted air flow through the vent holes of the oven
cavity, especially the cooling fan and air guide.
4. Reconnect all leads removed from components during testing.
5. Reinstall the outer case (cabinet).
6. Reconnect the power supply cord after the outer case is installed.
7. Run the oven and check all functions.
CAUTION: IF THE THERMAL CUT-OUT INDICATES AN OPEN CIRCUIT AT ROOM
TEMPERATURE, REPLACE THERMAL CUT-OUT.
