T1510W Daewoo touch control problem

[cnorth06]

I just picked up Daewoo warranty work and so far it's been a nightmare to say the least. The current problem is a standard lower end OTR microwave where the everything on the control works except for the start button. For example, you can set the time cook to a specified time and once you press start nothing happens. Originally when  i received the claim i ordered a whole new touch membrane and control thinking that would have it covered. When i installed the new parts, same problem. Where do i go from here? I i'd like the next trip out to be my last. Any help would be great, thanks!

If the fuse is good and the unit works but the high voltage stuff does not kick in I would say some sort of Triac is bad on the unit not giving it the go ahead to fire off the lasers.

More than likely a door interlock issue.

If one of the three interlock switches was bad would the light still be on in the cabinet? Would i still be able to program the micro? How do i test the switches with my multimeter? Ohm it out engaged and disengaged?

One of the 3 switches inded controls the light when the door is open, but when it closes, a whole new circuit is formed (or supposed to). The secondary switches might be  an issue, and  of course, you would OHm them out. Every microswitch has the markings NO, NC and COM written on them. There's probably a wiring diagram inside the wrapper to guide you. Korean micros are all the same, right down to the magnetrons.

If you want it to be your last trip out, then carry all the switches witcha.
