    My Whisper Heat by Lennox starts up with a big bang.
    My name is wally 213. My Whisper Heat by Lennox starts up with a big bang. Then it seems to run fine. The SER. Is 5893A12778 It sounds like it could be very dangerous and I need to know what the problem might be. I hope you can help me. The furnace is 17 years old, so it could be a number of things.

    I suggest you contact a Lennox service company NOW. The big bang is something you do not want to try and fix yourself.
