Hi,

Could be sequencer, motor or run capacitor faulty.


Test to see if motor is getting full 240vac.


Turn ALL power to furnace OFF and see if motor feels hot.

Also spin blower wheel and see if it will turn several revolutions before stopping or is it hard to turn.



Thanks,
Robert

I'm having same problem. Furnace heating but blower won't engage. I've checked with volt meter and get 120VAC. Should I be getting 240VAC?

Hi martynick,

Please start a new thread with your question so as not to confuse two different questions here.

Thanks,
