When your furnace's ignition control fails, this Dinosaur Electronics board is a direct-fit replacement for Duo-Therm, Hydro-Flame, and Suburban 24V AC furnace systems. It handles ignition sequencing and flame sensing so your furnace lights reliably every time the thermostat calls for heat.
A fuse on the board protects the 24-volt circuits from short-circuit damage, and dual flame sensing works through both the high-voltage connector and the edge connector at the same time for redundant, dependable operation.
A straightforward swap for RVers dealing with a furnace that won't ignite or won't stay lit.
