    Rheem Furnace Troubleshooting?
    The thermostat is set to "heat" and above the temperature of the house, so it should be running. However, the furnace will sound like it is kicking on, an orange glow appears in the top of the furnace. After a few minutes, the blower comes on, the orange glow goes out and it blows cool air for a short period before turning off. Is this a termal coupler and where is that located?

    I'm not sure. Maybe spelled wrong - thermal couple - - -? Any other thoughts? Flame Sensor?

    Your furnace doesn't have a thermo couple. It does have a flame senser. But if the flame never lites, the flame senser most likely isn't the problem, as it only senses flame. May be that you have a pressure switch problem, or there are many other things that it could be. I suggest calling in a pro. I bet they fix it in short order. Have them show you what they do when they fix it, so you have a little more knowledge of the furnace. A good tech will be happy to show you the basic operation of your furnace.
