Sub-Zero Not Holding Temperature
Not Holding Temperature 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
Air the bay side never sees
Concord averages 88.0°F in July against Oakland's 71.6°F, and a garage out here runs hotter still; a condenser rated for a conditioned room runs long, runs hot and fails years early.
Dirty or blocked condenser coils
The compressor overheats compensating for restricted airflow and eventually shuts itself down as a protective measure.
A worn or torn door gasket
Lets a steady trickle of warm, humid air into the cabinet that the compressor can never fully counteract.
