Amana Microwave Locked Up

[navagator]

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.



Thanks.

I found some very fine cracks in a couple of the keys and I  believe water got into the keypad when I cleaned it. 

After several days of drying time it's working again.

Thanks
