What do you have your heater hooked up to? A 20# propane cylinder? Are you using a red high pressure regulator or a silver low pressure regulator? Is this the original regulator that came with the heater? I could be a regulator pressure problem or a dirty flame sensor that simply needs to be lightly cleaned with sand paper. It's also possible your igniter is faulty or your brain box has a short. I've come across a few that just needed the brain box pushed a little in a certain direction to make good contact and work again, using a small wedge behind it. Sometimes just fiddling with it and cleaning it is all it needs. Good luck. Douglas

    I also forgot to mention that if the propane cylinder you are using is frosting up on the outside, then you have exceeded it vaporization ability to produce enough pressure to sustain a flame. You will need to hook up a fresh tank and see if that solves the problem or just use a larger cylinder like a 100# or 2 manifolded together if using if for hours at a time. Douglas

Coleman heater model 5445c700 propane camp heater wont light. It did work fine. When I hold the knob in the light position you can hear gas but it barely ignites then goes out. I've tried new gas and...

If you're using a 20lb propane tank (Gas Grill Tank), that may be the problem. Turn off the propane tank at the tank valve and disconnect it from the tank. Wait 5 minutes and reattach the heater hose to the tank. Turn the propane tank valve on very,very slowly until it's all the way open. Try lighting your heater now. If the pilot flame height returned to normal, that was the problem.

FYI - The Thermocouple has nothing to do with the length of the pilot flame. It's a safety feature that stops the gas if the pilot flame goes out for any reason.

Hope that solves your problem. Please let me know.

I have a coleman heater (central heating/A/C) Excel energy had a 2 hour power outage this morning unplanned and now I am trying to reset the thermostat so the heater will come back on) I had to reset the...

Hello, You may have this already solved by now but here goes. If your unit was running at the time of the power outage, you may have a limit switch kicked. This would cause your main blower to run non-stop with no heat. Gas furnaces has a main limit mounted on the wall of the heat chamber. This one should reset automatic when it cools down. Then you have a limit (maniual) reset on the blower casing. This is a small round device with two small wires coming off of it that goes toward the main board. If you can find this limit switch it will have a small button in between the two wires where they attach. Push in this button, if it clicks it should light the flame.There may be another limit on the burner casing. Try pushing this one also. When the power goes out when the flames are on this will build a lot of heat up near the blower causing this limit to kick off. Hope this helps.

Heater sometimes ignites and goes out. it repeats this step several times. then it will ignite and the blower comes on. it is a natural gas 80,000 btu furnance/AC. about 5 years old. make Coleman

The flame sensor rod should be cleaned, if that doesn't fix it check the combustion air switch. There should be an error code, look for a blinking light and code chart under the filter door.

What color should the flame be on a coleman

hi the gas goes along aburner tube then comes out of the burner then it hits a baffle in side the heat exchanger as long as there is not sooting the flame will look yellow , i would say the best thing would be to contact the makers of the furnace direct they should have a technical department , they might be able to offer more help or have there own people to look at the heater most of these companys have a warrenty on there heaters

Why does my heater light and go right back out

Most commonly if it lights just for a few seconds and goes right back out.....the flame sensor is not sensing the presence of the flame. This can most commonly be cleared up by cleaning the flame sensor.

The flame sensor is located in the burner area, it typically has a single wire leading to a piece of porcelain with a stainless rod protruding from the porcelain (mounted with a single screw) turn the furnace off, remove the screw, use some steel woal to clean the rod, put it back together and test it. BE SURE TO STAY CLEAR OF THE CARBIDE IGNIGHTOR......IT IS VERY FRAGILE.

I have a Coleman furnace model number 7681-8171/b. Most everything has been replaced on this unit from the circuit board to the flame censor including the firebox which was on the recall list. The unit...

Short of being able to look at everything Its impossible to say exactly what the trouble is. Does the board have a blink code showing and a legend that says what this is? What fuel are you on NG or LP? What does the flame look like (if you can see it) IE a lot of yellow, Some orange and Blue...?. Did anyone else look at the system and the thermostat? Does it have AC or HP on it too?

The only 1 thing I may be able to offer is this. On your thermostat (if it is not electronic) there is a needle pointer that points to a number it should be around .4 to .7 if set to a lower number the thermostat will cut the unit off well before it completes a heat cycle.

Ignition failure code on

Sounding like a flame proving device is failing to sense flame. Try to clean the device with some steel wool. It is located right next to the last burner looks like a thick wire. Take the steel wool and gently rub the carbon that has built up off. Should only take 4 or 5 strokes. Let me know it that did it. Ken
