Reset furnace (heater) often to get the fan to work.

Why do I have to reset my furnace (heater) often to get my fan to work? The thermostat works properly but the fan some time is not turned on. Reset the furnace and/or the limit control switch works for a while but the problem will come back.

You might need a new control board in the furnace or just a relay replacement. Anything more than a once a year reset means there's a failure somewhere.
