ComfortMaker Honeywell SV9541 doesn't heat
Posted: Mon Nov 29, 2010 5:47 pm
I have a ComfortMaker furnace with a Honeywell SV9541 gas valve. My heat will not come on. When you set the thermostaht to call for heat, the fan kicks on, the ignitor lights the pilot but there is no gas flow for the burners to kick on. The light flashes 6 + 1. Does this sound like a gas valve problem or control board or pressure switch?
