Big Mac 37 for Model Number MSD2756DEQ I have a MSD2756DEQ Model Whirlpool Side by Side Refrigerator/Freezer. SN 10507386YH, installed in my home May 2000. In the last year I have had the refrigerator side shows warm on my refrigerator thermometer. Because of a similar experience several years ago, I learned from a refrigerator repairman to take the back panel in the freezer compartment off to look at the evaporator. I have done that and each time in the past year it has been coated with ice. Using a hair dryer, I have melted the ice off, put everything back and it works. A friend suggested it could be a problem with the defrost timer. I know there must be some sort of defroster mechanism also. How can I figure out on my own, what is wrong and what part to replace?
Answer Hello Big Mac 37, First you need to make sure it is a defrost issue. The frost pattern will tell on the unit. If the frost is only across the top of the coils, the issue is an air flow problem. If the frost covers the complete coils, the issue is probably a defrost issue. The most common defrost component for this unit to experience is that of the adaptive defrost control 61005988. Please note that just replacing the part will not completely clear the issue. The coils have to start out with no frost so if this part is replaced, the coils need to be defrosted with the hair dryer to prevent an issue with the existing ice build-up. Read More...
