Trane Low Pressure Cutout

Medium

Tracer CH530 (CGAM/CXAM) — The suction refrigerant pressure fell below the low pressure cutout trip point.

Trane Low Pressure Cutout: The suction refrigerant pressure fell below the low pressure cutout trip point. This fault usually isn't an immediate stop, but should be checked soon.

Possible causes

Refrigerant shortage, restricted liquid line, or insufficient evaporator water flow.

Check steps

Check refrigerant charge, liquid line, and water flow.
