furnace problems

ihope iam doing this right as i am a newbe
i have a carrier 58gs-125 gas furnace
a couple of days ago i noticed an electrical smell. i also have a tron max 5 hooked to the furnace that was staying hot (it was making noise when the blower was not running) i turned it off it .that did not solve the problem.
i then noticed the furnace would start and light but the blower would not run i switched the blower from auto to on and it worked!! thinking the problem was with the honeywell 8000 pro thermostat i went into it using programers settings reset all settings put it back to factory default setting making sure it was set for gas and all was well so i thought. today the problem repeated itself this time i notice a noise comming from the blower area so i checked to see if the blower would turn freely and it does i also installed a new capacitor
any suggestions would be appreciated thank you

You may need pull the control board and look on backside for burn marks. It sound if run cap is good and motor feels cool then board is going to be the problem.

Yeah if it wont come on low spped but high runs id guess motor also.
Maybe try swapping the medium speed /low speed wires on the board and see if it runs.
"facts" have no relevance to this discusion
