Question about Heating & Cooling
There are basically three things that can go wrong with the Warm Morning .
Sensor shut off. There is a sensor button on the back of the unit with a wire going from it to the thermocouple. This sensor turns the heater off if the flue is blocked, however it will also shut the heater off if the wire contacts are dirty, or if the sensor has gone bad.
You can test this by bypassing the sensor. Disconnect the two wires from the sensor and reconnect them directly together. If the pilot stays on, your problem is here. Try cleaning the wire contacts first.
Pilot orifice. If the pilot flame is small and doesnt look healthy, the pilot orifice may need cleaning. The hole is very small and can get dirty. Disconnect the silver tube and clean with electrical parts cleaner. Never try to clean the hole with an object like a pin, you may damage it. You may have to slide out the burner unit to get at the silver tube. (Always shut off gas before disconnecting lines and after you reassemble, spray joints with soapywater and look for small bubbles which may indicate a gas leak. Dont use parts cleaner around an open flame.)
Thermocouple can go bad but this is not as common as the first two problems.

More than likely if your thermal couple is fine, then your pilot light gas line (usually the silver metal line going from the silver pilot button box in back of heater to the pilot light, needs to be blowed out with nitrogen. I've had this aggravating problem twice and the service cost me about $70.00.
