KRELAY TEST

2.Open the door and block it open.

3.Discharge high voltage capacitor.

4.Disconnect the leads to the primary of the power transformer.

5.Ensure that these leads remain isolated from other components and oven chassis by using insulation tape.

6.After that procedure, re-connect the power supply cord.

7.Remove the outer case and check voltage between Pin No. 1 of the 2 pin connector (A) and the common terminal of the relay RY1 on the control unit with an A.C. voltmeter.

The meter should indicate 120 volts, if not check oven circuit.

RY1 and RY2 Relay Test

These relays are operated by D.C. voltage

Check voltage at the relay coil with a D.C. voltmeter during the microwave cooking operation. DC. voltage indicated .......................... Defective relay.

DC. voltage not indicated .................... Check diode which is connected to the relay coil. If diode

is good, control unit is defective.
