Question about Coleman (5040B750) Patio Heater
I've cleaned the pilot light port. The ignition spark appears to work well. When propane does build up inside the unit and the spark is activated, it will light the gas from the main gas ports, but not the pilot.

If you are using the heater at temperatures below 40 degrees, ther will not be enough gas vapor to run the heater. If the temperature is above 40, look for an obstruction in the gas piping or gas valve itself. There is a small screen on the inlet side of the gas valve that you can inspect if you remove the inlet hose. Make sure you reinstall the hose using a teflon base pipe sealant on the threads.

The yhernocoupler would snuff the pilot if bad. What ignites the overhead burners? and what regulates the overhead gas supply? Look into this. Too much gas will not light as easily as proper balance gas and air. Even more so in a tower type heater.. Turn the gas on low and the pilot should grab it. Good luck

Hello, Most newer gas furnaces (propane or natural gas) has one of several different types of igniters. The most common one is called a hot surface igniter. This is a ceramic easy to break, glow coil, glowing igniter. Some has a Spark igniter that lights all the burners from a constant spark and some light the burners off a pilot proven /spark igniter. This one sparks then lights a pilot then the burners will come on. In any case if any of these types are not working they could be cracked or broke. Also the inducer draft motor has to be running, the little motor that hooks to the exhaust of the furnace ( if it has one ). This causes the pressure switch to close then the igniter should come on. My suggestion is to call a qualified service tech from your area to assist you. To determine which one of these may be your problem they will have to perform several test. Hope you get going soon. I hope this helped. J
