    Locating capacitor

    I have a lennox furnace AF80MPA100B5-A The a/c unit outside runs fine. the air inside blows cold air. After a couple hours the blower inside shuts off, the outside remains on and runs fine. I'm thinking its the capacitor. I shut the power, went up in the attic opened the front panel, and I don't see the capacitor. please help me locate it. I have attached pics.

    I don't see any in the picture but I can tell you that if you just follow the capacitor wires they will lead right to it.

    The conventional view serves to protect us from the painful job of thinking.

    The capacitor is right at the end of the capacitor wires as shown on the schematic. Your service tech can't find it?

    You are on the wrong path L.A.

    A young HVAC tech would likely have difficulty tracking down this problem.

    Don't spin your wheels and make things difficult and increase the cost get a professional.

    Stay away from companies that do one hour calls and send out flyers for whole system replacements. Stay away from Craigs list.

    Check the BBB before making an appointment.

    I suggest using this sites Contractors Locator Map to find a local company.

    If it's the Flux capacitor, it really doesn't come into play until the machine hits 88 mph. Maybe it's doing what it's supposed to do. Be careful though, if you don't know what you're doing, this can happen...

    A capacitor can still kill you, when the power is switched off.
