My ice maker will make ice after I thaw it out. After awhile it seems to freeze up and starts to make ice very slowly about a half a bucket and quits making ice. It has frozen water in the tray and some times the ice fingers are frozen in the ice. Could this be the bi-metal sensor (thermostat) gone bad in the ice maker?

My frig recently stop being cold. I thought it might be the thermostat. I changed that but it still doesn't get cold. When I change the temperature gauge, I do hear the motor running. I'm wondering if I change the Defrost Bimetal if the frig will get cold again?

My coil has started to freeze up and the blower fan does not come on at all. Does the defrost thermostat control the fan too?
