Initial problem was the condenser fan went out so when I got there replaced the condenser fan motor with a generic one That has worked perfect for me for on Sub-Zero before And cleaned the condenser very nicely meanwhile having it Unplugged for about 15 minutes. Customer called back said it’s not cooling still in the refrigerator section and VACUUM CONDENSER light on. Found system needs refrigerant. My guess is that there is a Freon leak in the evaporator although I did not see a ice formation on either trip And the customer said it stopped cooling overnight.
-So my question is does the condenser light come on for any issue? Isn’t there also a service light that should come up instead?
-What if the vacuum condenser light or service light Keeps coming back? I had a customer a year ago that wanted me to replace his compressor and exchanger with a generic one because it was readily available and the service light and error 40/50 kept returning even tho it was cooling perfectly.
Prefer technician input over paperwork.

Hello
You definately have a sealed system leak if it was low on refrigerant. The service light is because of the warm temperatures due to the refrigerant leak. You will need to find the leak and repair it or replace the evaporator. Matt Ace technician

Compartment Temperatures Normal with “VACUUM CONDENSER” Flashing (See Section … 8-10) in link below.
VACUUM CONDENSER” flashing
To clear error indicator after repairs, power OFF then back ON)

Items to check :
* Dirty condenser
* Condenser fan blade obstructed
* Condenser fan motor disconnected or defective
* No power from control board to codenser motor
* Possible early signs of Sealed System leak
