Sub-Zero Fridge Runs Constantly
Fridge Runs Constantly is usually one of a small number of specific, repairable causes — here's what to check and when it's worth calling a professional.
Common Causes
The fault line and the age of the housing
The Hayward Fault runs directly beneath Richmond through to Fremont, seismic gas valves are common here, and a fifth of the stock predates 1940 — both change what a symptom actually means.
A specific failed component rather than the whole unit
Most single-symptom issues trace back to one part, not a systemic failure.
Wear on parts that see the most daily use
Moving parts and seals typically fail before electronic or structural components.
Local conditions that matter here
This is the mildest climate of any metro we cover: a July average high of 71.6°F and barely fourteen degrees of annual swing. Condensers here are rarely working against heat. A fifth of the housing predates 1940, so what actually ages out is the install and the door seal, not the compressor.
