Question About Lennox International Inc. Furnace G24M SERIES
Furnace locks out...

During every heating sequence, the flame shuts off before the called-for temperature on the thermostat is reached and then the system locks out and has to be reset manually or wait for an hour and it resets on its own. Flame sensor has been cleaned and there's no loose wires that I can find.Any help would be appreciated. Thanks.
