This oven suffered the "fuse blows when door is opened or closed" malady. There's a convenient decal inside the chasis that states when you replace the fuse, also replace the primary interlock switch and the interlock monitor switch. The interlock switch definitely shows burn marks emanating down one of the terminals, so the inside probably is the culprit, and I will replace the switch. I didn't notice the burn marks on the switch until after I got done playing around with different door switch timing adjustments (to no avail).
There are a total of 4 microswitches on this unit. 2 mounted on an upper carrier, and 2 on a lower carrier. Each carrier can be adjusted forward or backward, thus adjusting when the door will trigger each pair. I initially thought maybe the switch timing was at fault, and I blew 3 fuses by trying to get the switches adjusted to operate simultaneously, first during door closing, then during door opening. Then I ran out of fuses. My question is where should these switch pairs be adjusted relative to each other? Should they be timed to operate simultaneously when the door is opened? Simultaneously when the door is closed? Should one set be timed to trigger slightly ahead of the other - either during door opening, or during door closing? By how much? Thank you for the insight.
