    Air conditioning circuit board
    I have replaced a lennox air conditioning circuit board but it keeps flashing. How do I find out what's wrong if I don't have an owner's manual?

    It should say on the door of the unit what the code is. If the board is a rework you should have the new info with it.

    By the time a person replaces all parts in a piece of equipment,he would have been better off to call out the experts in the first place,, most of the time it will save money to pay someone, someone that knows what he is doing. I sorry to be so blount but I myself learned this lesson the hard way when it came to thinking I could fix my car myself
