FF temp: 50, Freezer temps 5 at top and 25 at bottom
Compressor running and only drawing .93 amps
Frost pattern: Frosted from bottom until about 1/3 from the top where it is not frosted
Model # PSC23MGPABB
I responded to my client's "warming temperatures" issue and isolated all 4 thermistors (chilled them down for 5+ minutes and tested them at the J1 harness connector).
This box has been worked on in the past. Two of the thermistors were updated from black to white and the motherboard was replaced.
Tonight, the 2 old style thermistors tested way out of wack while 1 of the updated thermistors was in the clear, but, the other was on the line. So, easy enough, right? Change the three in question.
However, there is a 2nd issue regarding the FF door. The freezer door seals well with plenty of vacuum, but, the FF door lacks this vacuum and pops open every time the freezer door is closed. The gasket on the FF door is in excellent shape and there are no obstructions. Doing the dollar bill test yields the same pressure all the way around: It's just kinda weak everywhere.
Is this an air pressure problem? Perhaps the condensate drain is clogged and air can't move down it when the doors are closed? Could it be that since the air temp in the FF side is at 50 instead of 30 there is not enough vacuum pressure to hold the door closed?
Any reason to be concerned about the frost pattern? 2/3 of the evaporator is frosted. No visible evidence of leakage such as a ball of ice at the point where the frost stops. My thought was perhaps the corrupted data from the thermistors to the board could have been causing the board to run the compressor less.
