Possible Causes
Dirty air filter, Blocked vents, Oversized furnace, Faulty thermostat or anticipator setting
How to Fix / Troubleshooting
Safety: Turn off power before removing panels.
- Replace filter: Install a clean filter of the correct size and MERV rating.
- Open vents: Ensure at least 80–90% of supply registers are open to allow proper airflow.
- Check thermostat settings: For older mechanical thermostats, adjust the heat anticipator per manufacturer instructions. For digital thermostats, ensure cycle rate is set for forced-air gas furnace.
- Observe LED codes: Watch the control board during shutdown to see if a limit or pressure switch code appears, which can guide further troubleshooting.
Persistent short cycling with proper airflow may indicate an oversized furnace or duct issues, requiring professional evaluation.
