burnner problems

[Ron P.]

charged battery,checked fuse,changed fuel filter,changed unloader,changed pressure switch.
before doing this it stopped unloading properly and heat would stop after a min or two.
I hear the burner kicking on but no rush of air out of the stack, i can feel the heat.
Im thinking blower motor?[fuse is good]
What is my next step? I need heat ASAP.
THANKS FOR YOUR HELP IN ADVANCE.

Sounds like it is the blower motor. Check the wiring first, might only have a short. The only thing I see that you din't change was the fuel line, they deteriorate over time. Let us know the outcome.

burner motor

is there a way to check the motor without bench testing?

Ron, I believe when you open up the igniter you will be able to see it the fan is working.

thanks for everyones help

turns out that the orig unloader was letting air into the system and effecting the pressure switch.
After replacing both and having a wireing problem[wires were mostly the same color on the unit and the colors of the new switch were diffrent. Got all that worked out.
Turns out the new unloader was defective and letting air into the system and messing with the pressure switch.
my unit has both a pressure switch and a flow switch then diffrent colored wires and unused wires, then a defective new unloader and a unsure guy[me] trying to fix it all.
Well i did it!
pretty damn proud of myself, im sure it's nothing to most but it made my day. Also learned a lot on the way.
