Possible Causes
Severely blocked condenser
Heavy dust, grease, or debris on the condenser coils prevents heat release, causing system pressure to build.
DIY PossibleFailed condenser fan
The fan that cools the condenser is not running, causing heat and pressure buildup.
Requires ProfessionalRefrigerant overcharge
If recently serviced, excess refrigerant was added to the system.
Requires ProfessionalSafe Checks You Can Do
-
1
Clean the condenser coils
