    I have a Lennox 10ACB30-11P unit and need to replace the capacitor - I cannot identify the capacitor specifications printed on the side of the busted one (or the one on the sister unit) - It's a dual capacitor - I can make out 370 VAC. any idea on what I need? I thank you in advance for you time and help!!!

    This is strictly a guess. It being a 2 1/2 ton. I would try putting on a 35-5-370.

    That's exactly why...I have'nt the clue what this guy needs, as much as he don't. Sounds like a DIY, so I gave him one of the 15 probabilities. Better than nuthin right?

    BTW... I feel like I'm being stalked by someone

    look at the specs on the motor and on the side of the compressor, these units are famous for there bad capacitors, though, I recomend calling out a local certified service company, due to the fact a bad dual cap can still knock you on your kiester and possibly more. be careful call a pro......

    Our parts manager handed me one of those today.

    I've made larger capacitors out of dual capacitors a few times. Then add a second cap for the OFM.

    Looks like a good idea.

    I have changed capacitors from "close" to the correct uF (microfarad) rating on several Lennox units. They tend to be high ratings (60-80 uF) for the compressor half of the capacitor. If I were not a licensed HVAC contractor Lennox support would not have given me the this correct information, therefore I suggest calling a licensed contractor to instal the CORRECT part.
    Licensing laws are tough, and it's about time.
