Fan 50 Plus Pins Ignitor Board

The basic purpose of a Fan Control Igniter 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, after shutting the fan motor off, will wait for 1 hour and repeat the whole sequence again before permanent shut down. For 12-VDC Furnaces ONLY!
