I have an older Amana RBG622T microwave that's basically locked up. I was wiping the keypad down tonight with the dishrag and all the sudden all of the display LED's lit up and it won't do anything. I tried unplugging it and plugging it back in but it didn't help. When I plugged it back in the display shows 3 or 4 dashes in a row (which if I remember correctly was normal until the clock was set) for a few seconds then all of the LED's light up again.
Does anyone have any idea what could be wrong? I love these older Amana microwaves, I've been using them for years. Unfortunately they're getting hard to find now days.
