Good To Know

Q: How do I know if my furnace control board needs replacing? A: Common signs include a furnace that will not ignite, blows only cold air, or repeatedly cycles on and off. If the blower runs but no flame starts, the control board is often the culprit.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
