Complaint:
Air conditioning intermittently does not cool.
Cause:
If the evaporator shutoff valve (Y19/3) on the high-pressure side is not fully open, a vacuum can be produced on the
intake side which causes the pressure in the intake line to drop.
Remedy:
Check for low fill level.
Check of evaporator shutoff valve (Y19/3).
Procedure:
Connect pressure gauge. Check intake pressure. If the intake pressure is significantly below one bar, replace shutoff
valve (Y19/3).
Again read off the intake pressure using the pressure gauge to see whether the intake pressure is back to normal, approx. 2 bar.
Check whether the system cools now.
Remark:
Do not discard the removed shutoff valve (Y19/3).
Create a PTSS case and provide the value you are reading after valve replacement. Depending on the value, further
repair steps may be required and direction will be provided.
