Question about Sub-Zero 642

2 Answers

Sub Zero 642 started humming when the compressor turns on

Sub Zero 642. Getting a fairly loud humming sound above the freezer. Almost sounds like a fan hitting something but had it a part to day and that is not the issue. I know there are compressors above the unit and wonder if this vibration sound is the beginning of the end for one of the compressors.
If it is a compressor issue, is it realistic to fix one of these yourself? Is it just swapping out parts??

If the fan is good. then the compressor is going bad. It is not something you can replace yourself, due to freon and also the system needs to be charged properly or it would not be worth the money to repair it. You have to be certified with your EPA lic. to be able to buy a compressor or freon legally anyways. I would recommend calling a tech out and let them talk to you about replacing the compressor

MY FREEZER COMPRESSER ON SUB ZERO SIDE BY SIDE STARTS AND RUNS FOR 3 SECONDS THEN STOPS. IT WILL NOT CONTINUE TO RUN. FRIDGE IS OK.


This sounds like the start winding is trying, and the run winding is not. Check all capacitors. Check to make sure the wires are solidly on the compressor. Check the klixon switch, it should have continuity.

LCD panel and lights not working


On your Sub-Zero 642 Your display will not work unless your refrigerator lights work.
1st. Make sure your light bulbs are good.
2nd. Check your refrigerator door light switch.
3rd. The subzero uses a thermal overload to kill your lights if the door is left open to long.

I have sub zero 642 and my techinician says that I need a ice make valve replacement. He says it costs $495, does that seem accurate?


Sub-Zero a hallowed name in refrigeration, and the 642 side-by-side refrigerator/freezer unit is a landmark Yeah, it's that impressive. Dual refrigeration uses two compressors and three evaporators, I can tell you to never expect less than $300 for calling anyone to your home!

My sub zero 642 just starting making a humming


It is your evaporator fan. When the door opens power is cut to the fan motor.

Cannot reopen Sub-Zero 642 freezer door for 50 seconds


Yes, this is normal.  My 642 does the same thing. It seals to be more efficient while trying to cool back down after it has lost heat while open.

Freezer not working on sub-zero 642 model


Remove the top grille and touch the compressor on the left, above the freezer. Is it warm, can you feel it vibrating? If not, your compressor may need to be replaced.
