Hi I have a bryant heat and air unit,fairly 10yrs old. I have replaced the motor in it once last year . The motor will not start ,I have checked the thermostat,fuse and breaker,all seem to be OK. Not sure about the capacitor. Can you help?

Sound like you`ve pegged the next thing to check,, the capicitor,, is the motor the only thing not running? How about the compressor?
