This unit is 5 years old this month. Two years after purchase it began leaking water from the bottom front, randomly, I never had it repaired. A week ago I noticed the ice maker wasn't making any ice. Within a couple days I discovered my food was starting to thaw in the freezer and the refrigerator was not as cold. I noticed through the vent in the back of freezer there was ice on the bottom coil. Due to the generous information provided in this forum I cleaned the coils, forced hot water through drain hole, checked vents between both sides for no obstructions, removed back cover, felt and heard compressor kick on and continue running, evaporator fan is running. I removed the back panel from inside freezer, fan is running. What I discovered is the line coming from the back of the freezer into the thermostat and then to the coils is heavily frosted across the top coil, all the way down the right side coil, across the bottom coil, but when it goes up to the next coil there is no frost anywhere on the rest of the coils. Basically just the top coil, side and bottom coil has frost. Any help would be truly appreciated. Kenmore model 106.51103110

Thank you for your time and response. That is what I feared was wrong but you also answered my next question whether it would be worth fixing. I have another Kenmore side by side in the garage that is about 25 years old with no problems, was hoping I could count on this one to last that long.

Not sure if I would want another whirlpool since this one only lasted 5 years almost to the day. Would the random water leaking out the front (drain pan problem I think) have contributed to this leak problem? Do you prefer a specific brand over others? Thanks again.
