When these fans start to go, you often hear a tell-tale bearing squeal or struggle to ignite, which means it's time for a swap.

This fan is a critical component for safe and efficient operation, ensuring flue gases are properly exhausted from the combustion chamber.

5. Reconnect Wiring: Reconnect the electrical wiring to the new fan, ensuring all connections are secure and correct.
6. Test Operation: Before fully reassembling, restore power and conduct a test run to ensure the fan operates smoothly, quietly, and correctly, and that the burner ignites without issue.
