The freezer is not freezing

Everything in our freezer has dethawed and I've been trying to diagnose this fridge for a minute. I'm getting stumped.

  • There is no ice build up.
  • The fan by the evaporator panel is running.
  • The fan by the compressor is running
  • The LED on the inverter is ON and solid (no blinks).
  • We replaced the inverter board just to be sure.
  • The U-V-W connectors to the compressor show about ~15 ohms between them.
  • Thermistor in freezer is showing expected values for room temperature.

It seems and sounds like everything is running properly but the freezer is still room temperature. My current belief is that its a problem with the compressor. It is running, it's making humming sounds like the motor is running but the compressor itself is getting hot and all of the tubes coming out of the compressor are room temperature.

I'd like to not replace the compressor. From what I hear it is expensive and I don't think I can do it myself. If anyone has any other ideas, I'm all ears.

Hi @bryangonza93764

Here's the service manual for the refrigerator, that may help.

First go to p.53 (54 of 105 pdf) in the manual and run the 2) Self-diagnostic function during normal operation procedure as described and check if there are any error codes relating to the compressor being displayed i.e. codes 81 → 86 (see p.55 - {56 of 105 pdf})

If there are no compressor related codes and since the red LED on the inverter is on i.e. no blinks (see p.92 {93 of 105 pdf}) the control board says the compressor is working OK, This just means that it is working OK electrically but it doesn't mean that it's pumping refrigerant through the sealed system or that there is any refrigerant left in the sealed system to pump as it has all escaped due to a leak somewhere in the sealed system.

The only way to find out is to access the sealed system and measure the high and suction pressures in the system. To do this you would have to access the system and connect the appropriate measuring equipment. This would let you know if there's no refrigerant or if the compressor is not working properly. Not the sort of equipment you would buy for a one-off DIY repair. Professional refrigerator repairers would have the necessary equipment and the expertise to fix the problem.

What is the full model number of the refrigerator?

The best I can find out is that there are 6 RF263BEAESR/AA model variants i.e. RF263BEAESR/AA-00, RF263BEAESR/AA-01, RF263BEAESR/AA-02, RF263BEAESR/AA-03, RF263BEAESR/AA-04, RF263BEAESR/AA-05 & RF263BEAESR/AA-07 and they don't all use the same compressor. (At least I think they don't as some have different manufacturer's part numbers to the others e.g. MSV172AL2J/SM3 &, MKV190CL2J/E01. The prices vary between $US330 and $US470).

Of course it may not be a compressor problem but that there is a leak in the system. This would then depend on where the leak is and whether or not it can be fixed. By this I mean that if the leak is in the piping which is encased in the cabinet walls, then it is not worth it to repair it (no one would try to fix it anyway). If the leak is in an exposed section of the piping then it can be fixed.
