NOTES NOTES NOTES NOTES NOTES
‑ When replacing the 15A fuse, be sure to use
an exact repair part.
‑ If the 15A fuse blows immediately, check
the interlock switch, the relay 3 and 4 (on
the control circuit board) and the inter
lock monitor switch according to CHECKOUT
PROCEDURE FOR SWITCHES on page 8. And make
sure to check the microwave energy leakage
according to 1. ADJUSTMENT PROCEDURE FOR
SWITCHES on page 1, when the interlock
switch, the relay 3 and 4 or the interlock
monitor switch is adjusted or replaced.
‑ If the primary interlock switch,the relay
3 and 4 or the interlock monitor switch
operate properly,determine which of the
followings is defective : control circuit
board,blower motor,gear motor,high voltage
transformer,high voltage capacitor,high
voltage diode or magnetron.

‑If the high voltage diode is defective,
replace not only the high voltage diode
but also the fuse diode.
