I have a Comfortmaker furnace with General 90 controller. My blower motor stopped working and when I try to turn it on it gets hot, smells like something burning and no air.

Capicator was tested and it is OK. Motor is driving excessive current and just heats up. HVAC technician quoted $700 to replace the motor so I decided to try it myself.

Can someone share a step by step replacement process. I would like to replace the blower/motor assembly.

Thanks
