SENSOR 1) Disconnect sensor connector from
micom computer board.
2) Measure resistance terminal to terminal
(ohm meter scale: R X 1000)
Normal: Approximately
BK - RD: 5.1 Kohm
RD - WH: 2.1 Kohm
BK - WH: 2.1 Kohm
Abnormal: Infinite or several.
* Sensor cooking condition
1. Oven should be plugged in at
least 5 minutes before sensor
cooking.
2. Room temperature should not
exceed 95
°F .
3. Be sure the exterior of the
cooking container and the
interior of the oven are dry.
Wipe each off with paper towel.
4. The oven will not generate
microwave energy for the first
28 seconds of the sensor
cooking cycle.
NOTE : • A MICROWAVE LEAKAGE TEST MUST ALWAYS BE PERFORMED
WHEN THE UNIT IS SERVICED FOR ANY REASON.
• MAKE SURE THE WIRE LEADS ARE IN THE CORRECT POSITION.
• WHEN REMOVING THE WIRE LEADS FROM THE PARTS, BE SURE
TO GRASP THE CONNECTOR, NOT THE WIRES.
