go to electric motor shop . take oem capacitor. replace with exact replacement. rule on capacitors is uf or mf rating must be exactly the same. voltage can be higher. for instance if you have a 370 cap you can replace it with a 440 cap but never the reverse. to pull a bad 120 cap and replace it with a 230 cap is ok. but to pull a 440 cap and replace it with a 230 cap is a no no.cap rating must remain the same . volt rating can be higher but not lower.if motor still turns in reverse look at the reversing leads. see wiring diagram on the side of the motor. most replacement motors can run cw or ccw. by switching the reversing leads you can effect direction. usually wired up orange to orange and purple to purple. switch org to pur and pur to org and motor runs opposite direction. be sure you have a new correct cap for the new motor. every new motor should have a new cap and they are different usually.one motor might be a 5 mf cap and the new motor might require a 15 cap! be sure power is off and you check it three ways. looks off, checks off with a meter, and is off when shorted with a screwdriver.good luck

Cleaning the flame sensor has nothing to do with blower motor not turning on. You either one of the following problems 1 bad cap for motor. 2 bad motor. 3 bad limit on blower housing or 4 a bad board. You will need a volt meter to check for these problems. Try seeing if the fans runs with unit of and fan switch turned to on. Also does motor hummmm. Is motor cage free ( can check by manually turning) If motor doesnt humm and the cage is free wheeling then you will need to find out if you have power going to the motor. If you find out that you do then you will need to change blower motor. If you do not have power then you will need to check limit with continuity tester on volt meter. If that checks fine only 1 thing can be wrong and that is the board.

you need a meter that will measure uf (micro farads) it should read within about 10% of the rating 12.5uf otherwise you could charge it with an insulation tester (megger) and short the terminals with an INSULATED screwdriver to see if it discharges.

Testimonial: "Thanks for the help. I didn't have the propper equipment but a $7.75 risk was easy to take, so I bought capacitor in a local shop and It worked!"
It's the blower motor.........the bearings are seizing up when the motor is difficult to turn with power to it.
Generally, if the capacitor is bad, it won't turn at all or will quickly overheat and go out on internal overload.
If the motor feels "tight" when trying to spin it, the bearings are seizing and the motor will have to be replaced.
If there are oil ports, you might be able to spray some lubricant inside such as WD-40, but this does not always work and, if it does, it is only for a short time.....but it might get you by if you need the A/C and cannot get it repaired immediately.
I hope you find this information to be very helpful to you moving forward. :-)
