Consider these points:
- Incorrect settings can cause short cycling.
- Location matters. If your thermostat is in direct sunlight or near heat sources, it may read temperatures inaccurately.
- Aging batteries could lead to loss of communication with the AC unit.
Here’s a quick fix checklist:
- Reset the thermostat settings.
- Move the thermostat away from any heat source or sunlight.
- Replace old batteries of your AC thermostat.
