I have a oil forced hot air furnace and the blower motor when the
furnace shuts down the blower motor will go on for a few seconds then
shut off then go on for a few more seconds then shut off and continues
to do this for a few minutes then stop and when the furnace kicks on it
will do it again but stay on longer each time till it stays on till the
end and then all over again. This will do this not all the time but
more then it should and is annoying..Any help???? Thanks....Dave
It seems that your blower control switch, the OFF, is adjusted at too high
of a temperature.
When the burner kicks off, the blower should run, until the furnace plenum
is cool, and if the Switch OFF is correct, the blower will switch off. If
the switch OFF is to
high, the blower will switch on again, until the furnace is cooled down.
I hope I make sense, I have a hard time explaining things sometimes!>
