How to Fix / Troubleshooting

Safety: Unplug before moving sensors or accessing the control board.

Steps to reduce short cycling:

Check sensor placement: Ensure the cabinet NTC sensor is not in direct airflow from the evaporator outlet; reposition slightly if possible to sense average air temperature.
Stabilize ambient: Avoid placing the cooler near heat sources or in direct sunlight, which can cause rapid temperature swings.
Allow load mass: Keeping the cooler reasonably stocked with bottles helps stabilize temperature and reduce cycling.
Control PCB replacement: If cycling remains extreme and affects temperature stability, the main control PCB may have a faulty algorithm or sensor input and may need replacement.

Note: Some cycling is normal, but starts every few minutes with very short run times can shorten compressor life.
