Refrigerator not cooling enough


We once had a Kelvinator frost free fridge with the freezer on top and fridge on the bottom. It was a large fridge for its time and worked beautifully for 15 years or so until we noticed it was no longer frost free, and within a week of cleaning the evaporator (the fins inside the freezer) it would clogg up again and temperatures in the freezer were close to fridge temperatures. I rang the technos from Kelvinator and they came out to test, they fiddled with the thermostats and increased the hot wire element heating time inside the freezer (yes a heating element which was supposed to melt the ice more quickly) and it seemed to work ok for about three months, then the problem started to reoccur. I said to myself, I've exhausted every possibility I can think of, the technos (actual their top engineer) couldn't find it, so what was I to do? I started by noting when it started to build ice and the condition of thermostats, readings, time settings (it would defrost by running backwards 3 times a day), temperatures and condiotion of wiring and motor temperature. Everything worked perfectly. Hmm! I was about to give up when I noticed a bit of a smell coming from the evaporator tray at the bottom of the fridge, so I pulled it out and noted bright red crystals growing on it. But it was stone dry. Now normally, when a fridge defrosts the melted ice water goes into this tray and evaporates into the air. No water was coming down the tube, so ice or something must have blocked it. I could only see a short 2'' piece of plastic pipe coming out of the bottom of the fridge, the rest was behind a screwed on plate. Off with it's head. I decided to ruin the fridge than put up with manually defrosting it every week, so off came the rear condenser, swung out of the way and off with the screwed access panel. Eureka! there was the plastic pipe with a handful of ice on the outside and totally blocked with ice on the inside. The plastic pipe was alongside the copper pipe supplying cool gas to the freezer above. naturally, the plastic pipe froze and stayed frozen while the fridge was working, and this stopped melted ice draining away, causing the ice build up. Now that I found the problem, fixing it was a matter of minutes. I drilled a 1/2 '' hole in the back wall, ran a plastic hose on the outside of the fridge at the back from top to bottom and screwed the access panel back swung the condeser coils and started the fridge,. Within 1/2 an hour, water was starting to drip into the tray.

The fridge never again iced up and worked silently and faithfully another 15 years without a hiccup. I was 25 when I got that fridge and on turning 55, I shed a tear when my wife said, we need a smaller fridge, now that the kids not only left home, but we had our first grandchild. When the delivery man came to take it away and deliver the smaller Kelvinator, I hugged the fridge as they were taking it and I'm sure the guy thought I had been in the sun, not knowing its history and faithful service. The present Kelvinator is now 17 years old and hasn't missed a beat. Oh well, we move on. Cheers from the land of Oz.
