DCS Oven Temperature Fluctuating
Oven Temperature Fluctuating 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.
Local conditions that matter here
This is the newest housing stock of any site in the network — barely 2.5% predates 1940 and 17.8% went up since 2000 — so the install is rarely the problem. When a cooking appliance fails here it is usually the appliance, not the opening it sits in.
