Carrier HVAC Error Code 32: How to Fix It

Q: What does Carrier error code 32 mean?

Carrier error code 32 indicates a high pressure switch fault, meaning the system has detected excessively high refrigerant pressure. This can be caused by a dirty condenser, a faulty fan motor, or a defective high pressure switch.

Q: Can I reset error code 32 on my Carrier HVAC?

Yes, you can reset the system by turning off the power at the thermostat and circuit breaker for a few minutes, then restoring power. However, if the underlying issue isn't fixed, the error will return.
