Repair Procedure:
Check for leaks with your leak detector. If you find a leak
at a connection, tighten it then add refrigerant as necessary.
If a component or line is leaking (defective), recover all
refrigerant from the system. Replace the defective part and
then check the compressor oil level and replace missing
oil. Evacuate and recharge with refrigerant, then check AC
operation and performance.
Extremely Low Refrigerant Charge in the System
Tip: The sight glass is clear or shows oil streaks. The air from
vents in the cab seems warm. If there is a low pressure or
Trinary™ switch in the system it may have shut off the
compressor (clutch).
Cause: Extremely low or no refrigerant in the system. There is a
leak in the system.
Repair Procedure:
Add refrigerant to the system, at least half of the normal
full charge amount. Then perform your leak test. As an al-
ternative to a refrigerant, add dry nitrogen gas to the system
and then test for leaks.
Note: It may be necessary to use a jumper wire to bypass some
types of low pressure cutout switches to operate the com-
pressor (clutch) when you add refrigerant to the system.
