My williamson oil furnace is only blowing out cool air whats my problem?

The burner is probably locked out for some reason.


Should be a reset button on the burner.


If it runs after resetting but locks out again there is some problem, do not keep resetting because fuel may accumulate in the chamber if there is an ignition problem.


Call a tech for service.


Its blowing cold air because your blower is probably operated by a timed control that starts when the heating cycle is suppose to start.My williamson oil furnace is only blowing out cool air whats my problem?
That depend on when you have cool air..


The blower switching may need adjusting or switch replaced


The heat chamber should heat to a certain point before the blower comes on..


The burner remains on until the thermostat is satisfied then shut of the burner off..


The blower stays on until the chamber cools back down


It maybe be residual air in your duct work if you are feeling cool air for a very short time
