Sub Zero refrigerators in most cases are a dual evaporator and compressor refrigerator. This means if one side can be cooling fine while the other is warming up. When a refrigerators condenser fan motor fails it can create a no cool situation in both the freezer and the refrigerator side.

To diagnose the refrigerator and verify that the fan motor has failed requires little to no effort. On Sub Zero Refrigerators that have a grill on top remove the grill, if the grill is on bottom remove it as well. The grill on top will have three screws coming in from the bottom possibly as well as one or two spring claps holding it from the inside. If your Sub Zero has a grill on the bottom, removing the four screws in each corner will release the grill.

Now the the grill is off in either location look inside behind the grill, the fan motor will be in the middle, if the compressor is running and the fan isn’t it’s bad. To verify this, remove the two wires that connect to the fan motor, with a volt meter verify that 110v is present, if so replace the fan motor.

Most often a refrigerators condenser fan motor fails or stalls, it’s not unheard of for the main control to cause this issue, the volt meter check may be beneficial to you in the long run.

    I have tried for two days to free the hooks from the springs; my hands and arms are bruised. Is there a special tool? Vacuuming just through the vents is not sufficient; the condenser/grill cover needs to be removed.

    • Hi,

      On Sub Zeros the grill has two springs. The springs are clipped into the hard metal clip attache to the grill. The springs slide out of the metal clip no special tool. Some Technicians will crimp the hook closed so check for that. Good luck with you Sub Zero Refrigerator repair friend!

  6. I have a subzero 632 ref. I removed the icemaker 5 years ago. It stopped making ice, i don’t need ice anyway. About one year ago, I noticed that the fan is not stopping at all. I am not sure if it should be that way. It still gets cold on both sides normally. But it says ‘vacuum condenser’ which I did, the fan still is running all the time. I only have very few stuff in my ref. My previous settings were 0/35 degrees. Three months ago, I changed it to 5/45 degrees, but it is still the same. Everything else is OK. I hear the condenser still comes on once in a while. ‘ Vacuum condenser’ has been flashing all the time. Thank you.

My sub zero fan stops, then temp in freezer goes up in teens and twenties, I have to give push to to the fan blade then it starts running again, then the temp in freezer promptly comes down to – 5 in few hours, the fan runs Ok for few days, then it stops, so I have to repeat the same cycle. What is the problem and what to do?

  9. How do I remove the condenser fan and motor in the bottom of a 1991 501R. It seems very difficult to get to the back screws. The fan is not fixed on the motor and is banging around. Thanks for the help.
