Sub-Zero Compressor Hot To the Touch
Compressor Hot To the Touch 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
A failed start relay or capacitor
These small components are responsible for getting the compressor motor started, and are far more commonly at fault than the compressor itself.
Restricted airflow causing overheating
A compressor that's overheating from blocked coils can cycle or shut down as a protective measure.
Genuine compressor failure
Less common, but possible on older units, and the most expensive of the likely causes.
