Furnace blower fan issue

Ask a Plumber

Sometimes the blower fan continues for over a half hour after the burners go off .  It seems to be inconsistent.  Normally the whole heating cycle takes about10 minutes to complete. Is this normal?

    From the sounds of it, the blower relay may be sticking in the on position, but that is only a guess. You should probably have a technician come to check it out. If it is the blower relay, you’re wasting electricity while it is running and it is causing additional wear and tear on the motor. If it’s not the relay that’s the issue, it could be a more serious problem that could result in permanent failure.
