Siemens Continuous Run / Control or Sensor Fault

Wine cooler runs continuously without cycling off, even when interior feels cold.

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Cabinet sensor reading too warm, Door gasket leaking, Control PCB not terminating cooling cycle, Ambient temperature very high

Safety first: Unplug before accessing sensors or boards.

Steps to correct continuous running:

Check actual temperature: Use a thermometer to verify interior temperature versus setpoint.
Inspect door seal: Repair or replace the door gasket if leaking.
Replace cabinet sensor: If the sensor misreads, install a new cabinet temperature sensor (NTC).

If the unit still runs nonstop with correct temperature readings, the main control PCB may be defective.
