NOTE

- When replacing the 20A fuse, be sure to use

an exact repair part.

- If the 20A fuse blows immediately, check the

primary interlock switch, the relay 2 (on the
control circuit board) and the interlock monitor
switch according to,

“CHECKOUT PROCEDURE

FOR SWITCHES”

on page 6.

And make sure to check the microwave energy
leakage according to,

“1. ADJUSTMENT

PROCEDURES”

on page 1, when the primary

interlock switch, the relay 2 or the interlock
monitor switch is adjusted or replaced.

- If the primary interlock switch, the relay 2 and

the interlock monitor switch operate properly,
determine which of the following is defective :
control circuit board, blower motor, high
voltage transformer, high voltage capacitor,
high voltage diode or magnetron.
