Firebird won't fire

househero

Outside Firebird won't fire. Will start to hum for 10-15 seconds, but it won't fire, or even attempt to. Just carries on humming.

There's a load of oil, no air lock. The rdb doesn't lock out, red light doesn't come on. Just hums and carries on humming.

Took photocell and put it on a known working Firebird (parents) and it worked fine. So photocell is grand.

disconnect the p cell from the control box see if the boiler fires and goes to lock out if it does its the p cell if it doesn't it could be control box or coil

just be careful when doing above make sure you have power isolated first

just because the p cell worked on another burner doesn't mean its ok it could be throwing you off track

Wearb

Could be capacitor, seized pump, motor bearings or something stuck in the fan. All that along with what Jimf said.

Ok,how im reading this,what you have is the motor and fan running continous...,
It can be only one of four things,
1/ photocell
2.coil [open curcuit or not reading 100 ohms resistance]
3/motor [ not giving 53v to white wire]
4/control box
Follow Jimf advice on the photocell first

Is the hum just a hum or is it the sound of the fan whirring. If it's a light electrical hum, the motor is not turning. First establish if the motor is actually turning.
