All Season Comfort Control 12000 Heater / 1400 AC - WAVE FLO Technology - 110 Volt I had the heater portion running. It stopped putting out hot air and a red light on the control panel is lit up. It is on the middle bottom of the control panel. Looks like a water bucket with a brick in it. Need to know what that means, how to fix it and prevent it. ASAP This unit is only 18 mnths old. And if I knew where to find the name or product number on the unit, I could have looked up the manual.
