HVAC heater fan motor question.?

problem could be the capacitor but by now the motor has likely been damaged by overheating multiple times,,sound like you are capable of changing it yourself..i would recommend doing that at this point... a general replacement 3/4 hp motor should work fine...also get a new capacitor for the new motor...fyi-its considered a run capacitor even though it helps it start and run...a "start capacitor" is for belt drive motors and ac compressors and is always taken out of the circuit after initial start up either by a relay or a centrifugal switch.....the only problem you might have is the color of the wires on the new motor might not be the same as the old one..i would recommend taking the new motor out of the box at the parts place and having them point out each wire and its equivalent on the old motor,,perhaps even marking them with tape or splicing some of each of the old wires onto the new motors wires so all you have to do is connect it back the way you found it at home,,i guess this depends on your skill level,,i just dont want you to get that far and have the new motor burn up on you..also the new motor may be reversable whereas most oem motors are single direction...the direction of the motor is determined with the shaft pointing AWAY from you..perhaps get the parts house guy to figure out if new motor needs to be reversed and have him switch the reversing wires while you are there...,,dont forget to tighten the blower wheel set screw good after centering the wheel on the new motor shaft....hope this helps......dan
