To Next PageTo Next PageWhat to do if my Electrolux PLMV169DCC has a blown C/T fuse?
If the Electrolux Microwave Oven becomes inoperative due to a blown C/T fuse, first examine the monitor switch, relay (RY1), secondary interlock relay (RY2), door sensing switch, and primary interlock switch before you replace the C/T fuse. Also, if you replace the C/T fuse, you must replace both the monitor switch and the primary interlock switch.
