Sub zero: Refrigerator cools fine, feezer not
Posted 07 August 2005 - 07:07 AM
New compressor and coolant change 4 months ago with accompanying huge bill!
Current issue began a week ago when freezer temp began rising slowly from it's regular 5 degrees up now to about 34 degrees. The refrigerator top shows no change, and both top/bottom will cool down proportionally if thermostat is turned cooler, at least last I checked. Initially a stream of ice formed on the freezer rear adjacent and below what appears to be a drain tube ( which has a mesh/wire electrical thingy that runs down through it after passsing right through the fins/coils of the freezers internal "fan/evaporator etc unit"). I shut the unit down for 24 hours to see if a frozen drain could be the problem. When restarted it appeared that it might be cooling better, but temperature quickly began rising again after a very brief time of normal functioning. Removing the cover off of the freezers "etc unit" (see above), I found ice formed on the bottom of the cover, also across the bottom of the fins the coils are running through, and there was additionally a dense frost/ice coating on the "tubing" apparatus running diagonally across the face of the fin/coil component. By the time I stopped pondering the appearance of all this all the ice had begun to drip and fall and so I loosely scewed the top scews back in, to keep the fan in position, and left the bottom screws out putting a pan to catch water underneath hoping that allowing draining this way might reveal some info. No luck, water drained out, temperature kept rising, and here I am with a fridge that will keep my beer cold, but no freezer ice to fill a cooler! Hope you can help!

Is the evaporator fan (the one in the freezer) running?

The red arrows in the attached photo show the frosted tube/pipe length along the front. The frost diminishes along the tubes as they wrap around the size of the unit. The Blue arrows show the cable/wire that begins in front and then travels throught the evaporator and down and out the drain tube (a defroster cable??). The additional ice buildup, which is no longer visible at these higher temps, seemed to be a result of liquid pooling in the bottom of this tray/cover until it rose up into the fins of the evaporator.
Thanks for the quick reply!

You need some hands on diagnosis. Ask the guy to "blow out" the system and check for a low side leak.

Thanks for your reply, looks like you speak for the exalted grand master himself? Thanks to both of you for your help with this! Too bad I cannot tackle the issue myself. Appreciate your time. Does he share his beer with you??
