Thanks for your business!

The moderator for JA asked me to help. Can you restate the question, please?

my lennox G20 furnace will not come at times. The temp. on the thermostat will be below what it is set for and the heat on will show but nothing happens. If turn the heat off then back on it starts right up and will run through cycles like it should for a day or sometimes half a day then it starts doing the no start bit again. I turn the heat off and back on and it starts up again. The thermostat and ignition control board have been replaced. Please reply by email not text.

Let's try cleaning the flame sensor if you have not tried that. The flame sesnor is right next to the pilot and is a short steel rod with a ceramic base. It can be removed and the metal rod portion shined up with some steel wool or emery cloth.

Information for order # ***** did not help. I already cleaned the flame sensor it was the ignition control board.

The info did not help at all

This was just step one. I always try simpler stuff first. We would have eventually gotten around to ignition control if that was the problem. I was waiting for you to post back with results.
