Liz Again for Model Number MTB1956BEW Hi. Its me again. I posted about the Maytag refrigerator back on 6/3/14 and 6/4/14. Well the condenser motor fan was fine so I tried to find someone to give me a quote on a new compressor -- long story why I am trying to keep this fridge going. Any way no luck so I was about to pay $800 for a new fridge and decided instead to give a try to taking the freezer back apart myself and see what I see with the idea of replacing just the defrost thermostat. I took all the food out and unplugged. When I pulled away the back panel, there was solid ice built up all around the defrost thermostat in the upper right hand side - it was covered solid with ice ball that was about the size of 1/2 a large grapefruit. There wasn't any ice built up on the evaporator itself. It was high up so I am not sure how water would have collected and froze up high in the corner like that. I am letting the fridge sit over night and when the ice is all melted, I was thinking I will replace the defrost thermostat. Does it sound like it might be something else based on this new info?
Answer Hello Liz, The ice ball is formed when there is insufficient Freon in the sealed system so this condition is normally caused by a low Freon charge. Read More... Answered by AppliancePartsPros.com | Monday, June 23, 2014
