The food side of my Maytag wide by side refrigerator was 80 degrees.

Okay all you ladies out there, listen up. Yep, I am a girl and had never worked on a refrigerator before. I googled the model of frig and the problem. Finding that one of two things were probably wrong, I went to parts select and ordered both parts. Two days later they arrived. I replaced the coil and thermostat and waited one day -- the food side still did not cool down. I replaced the frost board and immediately the unit started to cool. I had called a repairman on Saturday and was told that they couldn't make an appointment until the following Friday because of a tremendous work load. I had the refrigerator running by Thursday, the day before anyone could even take a look at my refrigerator. Even though I spent $30 on a part I didn't need, I saved a bundle, the house call would of been more than $30.
