Have a maytag mfd2560hes refrigerator, a couple of years old. Stopped cooling and after eliminating all other possibilities, got it down to either the compressor or the start-up relay/overload capacitor assembley. Borrowed a "3-in-1" kit from a friend, installed it, and the refrigerator started running normally and cooling again. At this point I assumed the compressor was ok, and ordered a replacement relay assy. Got the new part, put it on, but now the refrigerator short cycles again and the compressor won't kick in. I checked the replacement part numbers and it is an appropriate replacement for my unit. I don't understand why it doesn't work with the new relay but it will with the 3 in 1. I would also like to know if it is safe to just wire a 3-in-1 kit in permanently since that seems to make it work. Any advice or direction would be appreciated. Thanks.
