Sealed System Door Loop Leak

Topics:

Troubleshooting:

For any suspected sealed system door loop leaks:

  • Isolate and pressurize the loop
  • Using nitrogen pressurize loop ay 150/200 PSI for 30 Minutes (especially R134A)
  • If pressure degrades more than 5 PSI, confirmed leak 
    • If door loop leak is confirmed, photograph hose connections to both ends of door loop lines and gauge reading.
    • Contact Sub-Zero Tech Line.
  • If leak is not confirmed, continue to troubleshoot sealed system as needed.

Answer:

If pressure does not degrade 5 PSI the loop does not have a leak and tech should continue with diagnostics.
