FAQs
Why is my Field Controls UV air purifier not working?
It could be due to a burned-out UV lamp or failed ballast; check indicator lights and replace the lamp annually.
How often should I replace Field Controls UV lamps?
Typically every 12 months, even if the lamp still lights — UV effectiveness drops over time.
What does a Field Controls vent damper do?
It closes the vent when the burner is off to prevent heat loss and improve furnace efficiency.
How do I troubleshoot a Field Controls power venter?
Check for blockages, motor function, and pressure switch operation — these are the most common failure points.
Are Field Controls products compatible with all furnace brands?
Many are universal, but always verify model compatibility, especially for venters and draft controls.
