Its not necessary when "Vacuum Condenser" light is blinking means That condenser is dirty. That light will come on if compressor running too long. Most common problem is that Evaporator coil in fresh food section is leaking freon. It still might keep temps ok, but compressor need to run much more to keep temperature you set. check back wall in fresh food section on left side at the middle, behind drawers. if you see moisture in one spot or a little bit of ice build up, then You will need to call people who can replace evaporator. It is pretty expensive fix. I made video how it looks to repair this problem. Thanks.

A) Hey find the breaker panel and shut off the relevant breaker for 5 minutes and put it back on.

b) Normally Sub zero fridge has its power on / off switch on top where you found the condenser. You can switch on and off from there too.

c) Your user interface (touch pad) should too have an on/off button.

Another tip on Sub Zero Condenser dirty alarm.....

You have to clean this condesner good. Use a small brush like thing. Also you have to take all that dirt dust out. Otherwise, when you switch on the fridge again it will suck that dust back to the condenser coil and alarm will come back. Do two three times of cleaning then it will solve the problem
