Dinosaur Electronics Ignitor Boards Fan Control FAN 50 PLUS PINS. Heater Ignitor Boards Fan Control Boards. The FAN 50 Plus Pins is designed to replace the new Suburban Fan Control boards and the Atwood HydroFlame Fan Control boards.
FAN 50 PLUS PINS Uses the new 6 pin Connector
The FAN 50 Plus Pins is designed to replace the new Suburban and Atwood / HydroFlame Fan Control boards as well as maintain backward compatibility with the Fan 50 Plus, and UIB Fan Control boards which have been available since 1994. This board can also be used to upgrade older furnaces to add the Fan Control feature.
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.
For 12 VDC Furnaces ONLY!
