Venerable Amana RR-10 Microwave
We love our RR-10 and are the original owners (since 1979). Chromed out
with stainless interior and digital touchpad. I do have a service manual but it does not go into detail on the digital module. The digital module in this particular model was made by Essex. Last weekend, someone used it (not personally witnessed) and the digital module (Touchmatic II) went dead. I don't know what mortal code they entered on the touchpad but it is truly dead. I have a rusty old RR-10 in the garage for parts. So, I replaced the tube thermal cutout switch (which was open) and the digital module. The rusty digital module works great but has a poor Wife Acceptance Factor. Unfortunately, the original module is still dead. As a further clue, when the the connector plug for the module is plugged in, the buzzer should chirp. The original doesn't even chirp. I took it apart and found a cap that had caused the underside of the PC board to turn color so I replaced it. I also cleaned to the contacts on an unenclosed relay, too. Still dead. Since a new digital module is $170 I was hoping to get some hints as to what would be the most likely part(s) at fault. Since whatever happened took out the thermal cutout sw, I thought there may be some kind of deductive logic that could be applied here. Thanks for any and all insights, Lar |
