    Hmm Replacement capacitor

    I during the process changing of the blower motor I noticed the capacitor was extremely rusty and it might need replacement
    on the capacitor tag it says
    620779
    0023
    with 2 bar codes
    that all the information I have on the rusty capacitor
    I checked online I found the capacitor with following specs 50/5 uf with 370 v

    I checked on sears catalog web site for the compressor model number CA36K-1T Thermal zone and it listed different part number
    620764 with following specs 35/5 uf and 440 v
    on capacitors web site it says I can not deviate on uf more than 10% however i can go with higher voltage

    the question is should i go with he number on unit with 50/5 370
    or the number on sears catalog website with 35/5 440
    thanks for all your help in advance
    or should I buy capacitor meter to double check the specs on my capacitor

    Just because it has rust on it does not mean that it needs replacing. If it aint broke don't fix it

    Always change cap when replacing a motor, it could've been a weak cap that caused the motor to fry. Call an hvac supply house, give brand and model # and they should be able to give you the correct cap size.
