I have a Maytag msd2343arw fridge. It worked fine for some time but recently the temperature in freezer
has gone up some and the fresh food side hovers around 40-45. My condensor fan motor had gone out several months ago ( it was stuck ) and the compressor was cycling on/off as well as incredibly hot. I replaced the motor and cleaned the condensor which seemed to correct the issue. But the fresh side never cooled below 40 again. I did some troubleshooting, first I pulled off the panel inside the freezer to find a giant chunk of ice on the top of the coils, the thermostat suspended in the ice, and a frozen drain. I melted the ice, unclogged the drain and put the thermostat back. Two days and still nothing so I turned the defrost timer to kick on a defrost cycle, no heat, so I replaced the thermostat/heater combo. Still no improvement, the freezer is cold but takes several days to freeze a large cup of water. The ice maker
works and ice is solid.
One thing I did notice is that if I unplug the lead going to the thermostat/heater ,I have 1-5 vAC , if I kick on the defrost cycle, it goes to 120vAC but within 20 seconds drop back to the lower range.Also, regarding frost on the coils (if it matters), after melting the ice for the first time, after 24 hours, the back top 2 rows of the coils had heavy frost on them and fresh food side was just at 40 degrees (back top left on the coils is freon intake from what I can tell) . The next day the fresh side was back up to around 45, I pulled the freezer panel again and the back two rows from top to bottom had heavy frost but none on the front two.
So just to summarize everything as it stands right now, some frost on top rear coils, all fans running, drain line is clear as well as vents from freezer to fridge. The compressor is running, of the two lines one is somewhat cold and the other is luke warm , the compressor itself is warm (from having my Home AC fixed I assumed they should be cold to the point of having condensation on the surface of the one line and the other warm-hot to the touch, but I may be wrong).
My wife is getting annoyed at all the spoiled milk so any help is greatly appreciated!
