I have a carrier 58mca060 furnace at a rental house that is driving me nuts. The blower motor doesnt have the juice to get it spinning (once it starts its fine) i took the run capacitor in, it tested bad, he gave me a new one. Worked for a day, then it stopped working again. The motor will whine until it locks out. I can see the blower turning very slowly, but it wont go without a push. Stupid me, i didnt look at the original for the specs. The new one is 5mf 370/440v. I dont have a manual to see if that is correct. Would it hurt to put a 7.2mf cap in? Could it be something else? Any help would be appreciated since i really dont want to call someone out! (Guy tested my motor and said the motor is fine) could dirty fan blades cause this? I didnt have my meter to see if the new cap id bad or just not powerful enough. Thanks!
