BE VERY CAREFUL sticking matches in any propane appliance! With the gas OFF see if you can physically see the spark when you push the ignitor, if yes, the problem may be the regulator or bottle pressure the only test i am aware of for the regulator is replacement.

Hi there,

are there other indicators that could tell you if the heater receives electricity?

If you have a power tester please test the plugs of the heater for continuity or try plugging the heater to a known good power outlet.

If you've plugged it into a known good power outlet and it still does not light it could mean that you have a wiring problem.

Hope this helps!

I have this model water heater. The past few days i haven't had any warm water and ive been hearing my water heater make strange sounds. I look on the little box and there's a light blinking 3...


Yes.
Copy following link for service manual by type of gas control valve:

Plug blower in separately and see if blower motor functions. This will eliminate blower as suspect.
Have plumber check wiring, test and replace blower temperature switch, test and replace pressure switch, and conduct routine maintenance

My heater will light and burn steadily for about 2 minutes and then it just turns off, even the pilot light. What is causing this?


Sounds like the Thermocouple is going bad. Or, since it's Propane, he Thermocouple has a lacquered finish on it from the propane. If so, locate the Thermocouple (see your Owners Manual) and using a strip of fine sand paper, polish the Thermocouple thoroughly. You don't want to actually sand it, as much as polish it. Then wipe off the Thermocouple with a cotton ball soaked in alcohol. Allow the alcohol to evaporate before attempting to light the pilot.

Also your should trace the Thermocouple wire back to where it enters the control valve. Try loosening the nut with your fingers. If it does loosen, finger tighten it and with the appropriately sized open wrench, tighten it only a 1/4 turn more.

If either of the trouble shooting suggestions don't solve your problem, the Thermocouple will have to be replace. You can buy one directly from Coleman online. Make sure you have your Model # & Serial # before ordering.

Hope this helps. Please let me know.

Pilot turns on but when I switch to turn it on,


When you light the pilot, are you holding it down for 30-60 seconds. When you release the pilot button, does the pilot flame stay lit? Or does it only go out when you turn the knob to on position. Make sure the pilot flame is heating the end of the thermocouple and that it's a strong blue flame, not a lazy yellow pilot flame. Make sure the tip of the thermocouple is not burn't off, which usually happens with lazy yellow pilot flames. Replace thermocouple is nothing else works.

Coleman Patio Heater wiring


This must be a top secret heater design. Coleman is dwfinately of no help. The whites go to the ignitors or the output of the spark generator. The black is generaly a ground. Good luck.

No Gas in Heating Element


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.
