is the blower running? and was the filter plugged?

Customer: replied 1 year ago.
No the the blower will not run. And have not checked the filter, but it will not even try to prime the system. If that matters. It was working last night and this morning. Got home from work today and it was cold as hell in here.
Expert:  BillyHvac replied 1 year ago.

Ok the blower not running is a there a fan "on" switch that you have tried?

Open limit is high temp cut out switch on the front wall of the furnace above oil gun. If it overheated due to no blower it could trip.

Customer: replied 1 year ago.
There is no switch to just try the fan. Just the main controls and when they lock out nothing works.
Expert:  BillyHvac replied 1 year ago.

Most oil burners have a fan/limit switch on front wall with a manual push/pull knob for fan.

Or is this a boiler with combustion fan?

Customer: replied 1 year ago.
I believe combustion fan.
