Unit starts then stops after a few minutes; short cycling without error code

Safety: Turn off power before moving sensors or opening covers.

• Clean filters: Ensure filters and coil are clean to stabilize airflow and temperature sensing.
• Check sensor location: Make sure the room sensor is in the main return airflow, not near a window, door, or heat source.
• Adjust setpoint and fan: Use a moderate set temperature and continuous fan mode to reduce cycling.
• Consult installer: If the unit is significantly oversized, consider control adjustments or zoning solutions.
