With this board installed in your furnace, the fan will no longer run all night blowing cold air. Board knows when the propane has run out or if the furnace did not light, and shuts the fan off one minute after the third try. It has the same great design features as the other Universal Ignitor Boards, but with an added fan control relay.
The basic purpose of a Fan Control Ignitor Board is to shut the fan motor off if the board fails to sense a flame after
the third ignition try. Thus, battery drain is reduced and the needless blowing of cold air is eliminated.
The FAN 50 Plus Pins , after shutting the fan motor off, will wait for 1 hour and repeat the whole sequence again before
permanent shut down.
