compressor & freezer fan always on

I am helping my neighbor there is no ice or frost behined freezer wall. After I plugged fridge back in it went into a defrost cycle. I replaced the cold control thermostat. he said its still running non stop but I dont have the time to sit there. Did I mention they are very senior citizens. Even if I dial down to # 1 or less its still running( so he says). Yes it turns off when I dial down to off, keeping in mind its doing the same thing with the new part.

Thanks for your time.

And one is the warmest? How cold is the freezer. It seems to be the cold control if it’s getting well below 0.

Hi WoodChuckie: Yes #1 is the warmest and 0 is off. My neighbor called me and he said ,yes it makes ice fast but it only cycles off when it goes into defrost mode. Maybe they sent a bad control. Can I ohm it out? I replaced it the same way the old one came out. I noticed what looked to be a second set of terminals on the cold control solinoid area, is that relevant?

Thanks for your time.

compressor always on…I double checked the freezer back wall and noticed that only a portion of the evap coils had frost on it. This now tells me that there is a sealed unit problem and not a thermostat issue. Time to buy a new fridge. remember cold control was replaced defrost timer is ok and heater and sensor ok. I hope you agree.
Thanks Will(n2mjo)

Yes, partial frosting means low freon. It can be repaired by a qualified tech but is not cheap. Check for estimates if you wan’t to consider that.
