Is small fan necessary.

I have a 20 year old Day and night furnace that was originally propane and converted to natural gas. There is a small fan that is going out. Was this only to be used for propane or is it still necessary for natural gas. Thanks

If the small fan is part of the furnace, (induced draft motor) it is still necessary.

Yes, the small inducer motor is ESSENTIAL for the operation of the furnace.

Without it fresh air to burn the gas can't be drawn in and the burned combustion gasses can't be expelleds through the vent.

For those reason, the burners will produce huge amounts of soot and carbon monoxide.
