This question refers to a Kitchenaid KSRS25K68T01 side by side refrigerator
that was purchased in 1998. We do not have an ice machine installed inside the freezer
In recent months, we found the vegatables in the crisper were alternately freezing or spoiling. This weekend, we found the freezer had warmed to point that the ice and ice cream had melted. The refrigerator was also quite warm.
We transferred the food to ice chests and began to look for a new fridge. But then, the temperature returned to normal freezing / cold levels. We now need to know if there is a reliable fix that will stop this abnormal warming / cooling behavior.
For a moment, while looking through the back bottom opening, I saw a stream of water flowing through a small hose into a plastic tray insert. Then, silence: no fan or compressor sound for many minutes. Now, 20 minutes later, the unit is humming and the fan is moving.
On our last service call, the compressor was working fine but the fan that cooled it had stopped running. Now I can see the fan running normally. It is normal to feel the air in front at the bottom. The compressor is quite hot to the touch.
A few months ago, I blasted the coils with compressed air -- cleared them but didn't help the dust situation in the rest of the house! I will get a brush today and clean the coils manually. The build up is not anywhere what it was previously.
Is the cause of the alternating warm / cold condition likely to be an electrical component going bad? If so, which one(s)? Will it pay to have it fixed? Alternatively, is there a simple mechanical fix, such as adjusting internal settings? As a last resort, we would buy a new fridge if you indicate that a reliable repair could be quite costly. What would you do?
