Our Whirlpool ED22RF seems to be cooling normally but the frame of the refrigerator is very hot - almost too hot to touch. The compressor is also hot. We shut if off, cleaned out all the dust (a lot on the coils) and have started it again. Its cooling well again but teh heat around the inside of the door on the frame or base - is heating up again. I had been so hot that we were afraid it could start on fire. What can you help with?
