The FAN 50 Plus Pins is designed to replace the new Suburban® and Atwood® / HydroFlame® boards as well as most OEM fan boards and the original Dinosaur Fan Control boards which have been available since the middle of 1994 for use on most electronic furnaces, except the DuoTherm® 900.

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.

The "Fan Control" feature must be used for proper operation of this board.
