Short-cycling kills compressors. Here are the six causes, in order of frequency, and how to diagnose them.
Suction pressure hits the low-pressure cutout, unit cycles off, pressure equalizes, cycle repeats.
Head pressure rises, high-pressure switch trips. Usually dust, lint, or Tampa Bay grease film.
Motor cannot pull to run speed, thermal overload trips. Listen for the hum-click-hum pattern.
Original sizing error. Short-cycling is constant regardless of load.
A 1°F differential causes rapid cycling. Open to 3–4°F.
Partially blocked filter-drier or TXV. Read superheat to confirm.
