Possible Causes

Failed indoor blower motor on Bryant furnace/air handler, Faulty airflow or pressure sensor on indoor unit, Blocked air filter or ductwork causing abnormal feedback, Communication error between indoor control board and thermostat regarding airflow status

How to Fix / Troubleshooting

Safety first: Turn off power to the furnace/air handler at the breaker and service switch before inspecting internal components.

Steps to troubleshoot:

  • 1. Check air filter: Remove and inspect the Bryant-approved air filter. Replace if dirty or clogged.
  • 2. Inspect supply and return vents: Ensure vents are open and not blocked by furniture or debris.
  • 3. Listen for blower operation: With power restored, command the fan to ON at the thermostat. If the blower does not run, a technician should test the blower motor and control board.
  • 4. Inspect indoor unit: A professional should check the blower wheel for obstructions, test the ECM or PSC motor, and verify any airflow or pressure sensors connected to the Bryant control board.
  • 5. Clear code: After correcting airflow or blower issues, power cycle the system and confirm E16 clears.
