I am having a problem with my Maytag side-by-side fridge-freezer, model # MSD2655HEW. There is a buzzing sound, which is very difficult to pinpoint the location of, but it is an electronic type of buzz. It seems to be coming from the freezer side of the unit, as opposed to the fridge side, but I can't be certain. Every minute or two, it buzzes for about 2 seconds. This has been going on for a couple of weeks, and I've been ignoring it. However, now the freezer is not running cold enough, and things are beginning to melt. It seems that it could be stuck in defrost mode, since it is running and is cold, but not cold enough. The freezer is not iced up. I will follow up with a better location on the buzz, if I get one.

Your freezer fan may have seized up from lack of oil, also check under the unit and clean it well. The coils should have all dust and dirt blown off and washed off with a water hose sprayer. Remove the cover to the freezer coils and if fan is not turning when you plug it in then you will need a new one. They only cost about $15.00 and have two wires and a ground wire. It is very easy to replace. Take the old one to parts house so they can match it for the type and rotation. You will need to take in the blade, too. DrTom4444
