Question about Honeywell L4064B2236 Fan/Limit Control Heater
The pre igniter fan blows constantly but ignition to pilot light does not light the flame. The furnace is 20 years old.
Sounds like you may need a new electronic control module. This is a rectangular shaped plastic box that has wires coming out of it. This is what tells the pilot to light on these older furnaces.
