Cold boiler

Sorry for the slow reply.
If you don't have it fixed, what is the brand & model number on the primary control? If it is a Honeywell or Beckett 7184, push & hold the reset for 45-60 seconds then release. If the burner does not fire, DO NOT try it again. There are many things which can cause an oil burner not to fire. If it is anything except a clogged nozzle, each time you reset it, you are pumping fuel into the chamber.

it is a beckett 7184, it has the beckett cleancut fuel unit on it. it will run gfor about 20 secs and then the light starts flashing again, about once every 1/2 sec. i do not have 24 volts on it or from my aquastat.

burner lock-out

It's not firing or it's not sensing that it has fired. STOP reseting it before you flood the chamber with oil. Call a qualified oilheat service provider.
