Possible Causes
Thermostat or sensor placed too close to evaporator, Control board hysteresis issue, Oversized unit in very small space
How to Fix / Troubleshooting
Safety: Unplug the cooler before moving sensors or panels.
Steps:
- Check sensor placement: Ensure the temperature sensor is not touching the evaporator coil or directly in the cold air stream. Reposition it slightly away using clips.
- Improve ventilation: Provide adequate clearance around the cooler so heat can dissipate and the condenser does not overheat.
- Stabilize load: Avoid frequent door openings and large, rapid changes in bottle load.
- Control board replacement: If short cycling persists and sensor placement is correct, the main control board may have a faulty control algorithm and may need replacement.
