Brand: Sub-Zero

I am not getting any power to the fan or compressor.
I disconnected the plug that leads from the power source to the box below the door switch.
there is power going into the box but not going out of it meaning supplying the compressor and fan ect

Cleaned the condenser coils, everything working fine. Will clean better with foaming spray and check reservoir pan when I go back.

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.

I received a call today. Homeowner has a sub zero, freezer had salmon in it, unit was turned off for construction and fish thawed. Now the unit (per the home owner) smells like rotten / spoiled salmon. Calling me asking how to clean it or get rid of the smell.
Any thoughts. Besides cleaning with Bleach, vinegar and water, baking soda, ? I am sure I am his last call. What would keep the smell?

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

The refrigerator gasket hasn’t been closing properly for months. The interface on/off won’t respond nor the freezer/ refrigerator down pads. Where is the control board?

What does this sound like?
I need a parts breakdown and dissembling instructions. Also a service manual.

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.

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 have a subzero 590 that is dripping water. I need to check the lines going to and leave the water reserve tank. But I don’t know how to get to it.

I did replace the compressor and evaporator and heat exchanger on the sub zero model 680/s
Everything is running but not compressor,
Please I need advice and seal system service manual .

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?

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

SUB ZERO FRIDGE SIDE How to adjust the fresh food door Because it is tilting with The top over to the right. I tried adjusting based on what I found online but it only made it worse and scrapes the other door when you open it. Can I please have the manual and for schematic of this fridge

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

the freezer is not cooling and has made ice in some time
the fridge is not cooling.
i check the condenser fan it is running but both composers are VERY VERY hot.
i did clean the coils but there was not much dirt to be cleaned.
i have also checked the water inlet valve for the ice and it seems fine

I have had several sub zeros in the past couple months with this issue and I don’t know how to address it.
The ice maker does not make ice even when you select max ice on the display. There is a valve by the filter and then one more before the ice machine with a weird sensor on it. I first forced the original icemaker through a cycle by twisting the gear it looks like a Frigidaire icemaker and it went through the test cycle including filling with water at the end. But the customers all said that it only made that one batch of ice that I forced it to fill for.
All those customer said they replaced water filter before and still no ice. Reset the fridge. No ice. Checked for frozen fill tube. Made sure the water pressure is good. Made sure the switches by the ice machine work. It seems like only thing left is the main board that controls the power to ice maker and Even that makes me feel weird because why does the icemaker work when I set to max ice and forced the gear?

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

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’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?

So originally if compressor is The Refrigerator in the freezer were extremely extremely hot and they both were not working properly I cleaned out the condenser coils and I’ve recommended that they shut the machine off for some period of time to cool the compressor is off they have done that.
Now after doing that the refrigerator compressor is working fine however the freezer section is only Cooling as if it is a refrigerator also they have mentioned that the compressor is making noise I do see that someone has replaced the start relay on the compressor with a 3in1 before I go back there I would like to know what the temperature the high and the low and how to check it on the compressor should be and how to refill it with Freon if it needs

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.

When I run the diagnostic it comes up with an error for fresh food “Thermister error 02 3x”
“Z3 evaporator thermistor “
But on the diagnostic diagram it says to check reading on zone 3 thermister and condenser thermister leads which I couldn’t get to.

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