Unit cycles on and off very frequently (short cycling).

Safety: Unplug before moving sensors or accessing the board.

Steps:

• 1. Verify ambient conditions: Ensure the cooler is not installed in a location with large temperature swings (e.g., near a window or HVAC vent).
• 2. Adjust set point: Change the set temperature slightly higher or lower to see if cycling behavior improves.
• 3. Check thermistor placement: Ensure the sensor is in free air, not touching the evaporator plate or a bottle.
• 4. Improve ventilation: Provide adequate clearance around the unit to reduce rapid heat buildup.
