Question

Condenser fan motor and capacitor replacement


Tomorrow I have to buy and replace my condenser fan motor. Question is do I need to buy a new capacitor also. Present one is less than a year old. The tech who put it in convinced me to pay a lot of extra bucks for it but since then I am not sure I trust him. The system is a split setup Coleman inside and Armstrong SCU10E36A-1A condenser outside. Present fan is AN A O Smith F42C52A45. Plan on replacing it with an Armstong Ducane 42521-001 and an 89M77 cap if I need to. Prompt answers appreciated as I am only getting cold air now by oiling a nonoilable bearing???

Condenser is fixed. Local (60) miles one way had parts coolling now slowly, outside temp is 99. Mfg of old cap says I could have used it but I followed hvactech126 advice and replaced it. My new question is it any good to anyone or do I need to dispose of it in some special manner????

By replacing the cap when you put in the new motor, you did the right thing.

No special needs for disposal.

shouldn't a used cap be discharged before being tossed?

If you want to run a screw driver across the terminals to discharge it, you can. By now it should already have dissipated its charge9since (7/15).
