  • g23 not lighting 100% of time

    The g776 ignition module is at fault. Install a 30w33 ignition upgrade kit. Easy to do. Took 30 minutes. I found one on ebay for $115. Next best is about $162.

  • Efficiency Rating and life

    I own a Lennox G23(X) furnace, installed in 1998. My question is what is the efficiency rating, and what is the normal life of this type of furnace?
