Primary Diagnostic Causes & Field Remediation
Compressor Thermal Overload Lockout
If the condenser coil is blocked with dust, heat cannot escape. The internal thermal switch trips to prevent catastrophic compressor motor burnout.
Refrigerant Leak (Low Charge)
Microscopic pinhole leaks in copper line-sets reduce refrigerant pressure, causing the unit to run constantly while blowing room-temperature air.
Thermistor Bottle Probe Drift
A faulty liquid probe or disconnected temperature sensor falsely reports 55°F while the room warms, preventing the compressor from engaging.
Frequently Asked Questions
How long can wine stay at 70°F before it is damaged?
Wine bottles have high thermal mass and warm slowly. If the cellar air hits 70°F, liquid temperature lags by 6–12 hours. Fast intervention within 24 hours prevents irreversible oxidation.
