Heater Blower will not start. Code on led is PF.
How do I correct and or repair?
Thanks.

If you have a ECM motor in that furnace you better call a Carrier dealer for repair. That is a very expensive two piece motor. The main motor,a electronic bell housing and a board for selecting blower speeds.

If this furnace gets played with by people who do not have the knowledge to work on it you will spend a small fortune for parts if they short out.

This is the only information I have for that unit. Sorry I cannot help you.
Note you might the door on the furnace listing the trouble codes.
