Carrier Carrier 25VNA Infinity Greenspeed Variable-Speed Heat Pump CODE-62 Error Fix: Infinity Code 62 — Compressor Protection (High Speed)

Error code CODE-62 on the Carrier Carrier 25VNA Infinity Greenspeed Variable-Speed Heat Pump means: Infinity Code 62 — Compressor Protection (High Speed). The Infinity System Control displays "Code 62" indicating the compressor has triggered a protection fault while operating at high speed. On variable-speed systems, the compressor ramps to high speed during peak demand (extreme heat or cold). Code 62 at high speed can indicate: (1) Dirty condenser coil causing high discharge pressure at high speed — clean the coil. (2) Restricted airflow at the indoor unit (dirty filter) causing high suction temperatures at high speed. (3) Refrigerant overcharge — excessive charge causes abnormally high discharge pressure at maximum speed. (4) Electrical issues — the inverter drive drawing excessive current at high speed. (5) Compressor mechanical issue — the compressor may be working harder than normal due to internal wear. The system will reduce compressor speed or shut down to protect the compressor. If this code appears frequently, have a technician verify the refrigerant charge and check the condenser coil.
