Brand: Sub-Zero

Hello, I have ice dispenser flap that is not closing all the way, on a Sub-zero side by side, because it looks like the heater on it has shorted and made a bubble on the surface. Can this part be replaced? PS it is not the round dispenser flap on the refrigerator door. It is the flap that is in between the wall that separates the freezer and refrigerator.

We nee your suggestion regarding repair of Subzero,mod.#650/F,
,freezer on the bottom,17 years old.
The problem is the drain hose broke off in the fresh food section
by the wall and we are not sure how can we replace a hose without removing
the whole unit from the cabinet .We are going to install a drain heater (add-on),but it’s pretty simple.
If someone has experience how to replace this hose without removing a fridge,
please let me know
Thank you in advance

I am working on a subzero refrig. Model# BI-36U/S/TH
The unit was warming up and found the condenser fan not running.
I had power to fan motor, so I ordered a new fan motor and went to install
It but the new one did not work. But I am getting 110v to fan.
Could it be the main control board causing the issue possibly ?
Any help would be great.
Thanks

Hello
We have A Sub-Zero refrigerator that the (Vacuum condenser) light will come on within 24 hours after resetting. This is A dual compressor system and the unit is running prefect temperatures in the Freezer and refrigerator section. The freezer is at -1 degrees and the refrigerator is +38 degrees consistently. The condenser and condenser fan motor are clean. We even removed the condenser motor and cleaned the condenser with Co2. This condenser is spotless, you can shine A flashlight through it. I know the vacuum condenser light is an inefficient unit operation error. We pulled both evaporator covers in the fresh food and freezer section to verify they both have an even frost patter, we wanted to make sure there was not A starved evaporator before tapping the sealed system. We called the technician line at Sub-zero, they told us to tap the freezer and refrigerator section to check the pressures. We are not going to do that with perfect operating temperatures and even frost patterns on both evaporators. With perfect cooling temperatures in both sections is there any other suggestions before moving to the display board? Thanks in advance

I have a tech working on a Sub Zero refrigerator that the drain line keeps clogging. He called Sub Zero tech line and they recommended a part # 4202530. Another company said it needed a heating element, but the photo shows no heater. Can anyone that has installed this item explain to my tech how to install it?

Thank you all for your help.

My fridge isn’t cooling. The evaporator is only frosted on about the top 1″ of the evaporator. I’m aware that the evaporators are notorious for leaking. How do I locate the leak? Will a leak that small show up with a bubble type solution, or do I use a sniffer?
When it comes time to evacuate the system, I have manifold gauges, but they’re set up for automotive R134a. What are the correct fittings for the R12 system? It looks like 1/4″ flare, but I can’t tell for sure. In the automotive world the low and High side have different size fittings, but on the fridge they look to be the same.

Thanks,
Don

You can see when we close the door, the door seal gets sucked in like a vapor lock . Its takes a 220 lb. strong guy to get the door open it seals that tight. The homeowner cannot open their refrigerator.

I need some advice from our subzero experts.
Complaint: Not Making Ice.
We found the unit with the icemaker arm bent around from the bucket being pushed back on the arm.
We replaced the icemaker and as the water level was low and it is in a rental home we removed the filter and installed a factory by pass plug.
I started the unit in Max Ice. The icemaker cycled around twice and filled to the correct water level. We thought all was good and stopped to double check it the next day, No Ice.
I checked everything over again, drawer switch etc. ok.
After posting on psanet we replaced the complete water valve w/flow sensor. I opened the valve sensor and found it had droppings in it. We thought we were ok.
I started the icemaker again on Max ice and stopped to check it again 2 days later. Still No Ice.
The wiring seems good . Power to the flow sensor comes from the Low Voltage Board and Power to the icemaker comes from the high voltage board.
Factory tech line doesn’t think it is a board.
Any advice would really be appreciated.
Thanks in advance.

From what I could diagnose, I need both thermostats, but I don’t have that part number information. Do you guys?

The unit was freezing at the bottom and not cooling properly.

Already have replaced the fresh food evaporator and filter drier, and customer states they are still having cooling issues. I don’t run into many of these and have spent quite a bit of time there, was hoping someone here might have a clue.

We could really use some help on this unit.The icemaker is not working.
We can start the icemaker, it will cycle and fill. we leave it on MAX ICE. After a day it will dump 3 cubes. We have replaced the icemaker and removed the water filter and installed a bypass plug.
What are we missing?
Thanks in advance.

Customer states this unit is down to 17 degrees below zero and stuff is frozen rock hard. This is a freezer only unit. States it does not change temperature when adjusted warmer. Just stays at -17 degrees. Serial number is . I don’t normally work on Subzero. Any suggestions on what I should be checking will be welcome. Thank you

Hello
I am working on a Subzero two drawer unit that is not cooling. Do you have any information on diagnostics ?
Thanks

This unit is in an unheated garage, seems to run constantly. Have checked major components and they seem fine, I must be missing something?

I have a 2 drawer Subzero ref that will run for about 3 seconds and shut off. If I plug in with
top drawer unplugged unit will run and stay running until you plug the cable back in. All three
thermistors are good, evaporator was changed a year or so back and has a good frost
pattern currently. Touch pad checks good. No visible bad spots on either board.
So does anybody have any input on which of the two expensive boards is bad?

This sub-zero ice maker is only making a handful of cubes. It’s been not working correctly for a long time. The unit that’s in there is a 4317943 & I’ll be replacing it with the same. But the customer was asking if there was an OEM sub-zero ice maker that should be in there in it’s place? I didn’t think so but wanted to double check with you guys.

Replaced main control board because it wasn’t sending 120 to compressor and it started working then had redo because stopped cooling for a day again and went up to 60f for a day. When new board finally sends voltage to compressor it clicks like 4-5 times revvs up several times without holding a constant run then on fourth try compressor seemed to start running good. I’m thinking maybe temperate sensors not telling the board to send voltage but why would the compressor seem to struggle to run? I’m thinking replace sensors and compressor. I ran through diagnostic everything on the board seemed to test good.

My Sub-zero refrigerator stopped making ice .

We’re on a subzero that I need part information on. Specifically the heat exchanger and fresh food evaporator. Do you guys stock these parts? Can I get them from you?

My Subzero refrigerator is not cooling at all. Any suggestions?
