SOURCE: Patio Heater pilot lights won't stay lit

crappy pilot flame (not properly heating the thermocouple), bad thermocouple, thermocouple loose where it screws into the pilot safety valve, bad safety valve magnet.

One or more of those is the problem.

Oh...there is also a saftey switch...in case it tips over. It will also cause the pilot to not stay lit (if the switch or wires that go to i are faulty)

SOURCE: Nexgrill patio heater won't stay lit

I called Nexgrill technical support at 1-800-913-8999. They are sending me a new thermo couple to keep the valve open when ignited - so the patio heater will stay on. I needed to give them the serial number (inside the propane tank door) and fax them a copy of the receipt.

Hope this helps.

SOURCE: Coleman Gravity Floor Furnace need millivolt gas valve & pilot ki

Go to www.grainger.com and look for a "power pile generator" this is a millivolt thermocouple that may be just what you need to make your heater work again

What is likely happening is that the pilot flame cannot reach the thermocoupler. This is usually caused by corrosion or other blockage of the gas to the area where the pilot lights. Thus resulting in a small flame or no flame on the side the thermocoupler is located. Fix this by cleaning out the corrosion or other blockage in the pilot assembly. I have found that small spiders like to make their homes here which causes the blockage of the gas for the pilot. The pilot assembly has three parts to it. The ignitor electrode, the pilot light tower, and the thermocoupler. The ignitor electrode has a wire that goes from it to the push button ignitor. The pilot tower is located in the middle and has a gas line going to it from the gas valve (control knob). The thermocoupler stands next to and on the opposite side of the ignitor electrode. It also has a copper line from it to the gas valve.

Unfortunately, the Sunjoy you have, which is the same model of two I have to keep running, is difficult to service. Parts are not readily available either so be careful when you take it apart. They do not sell the individual smaller parts in this model and therefore make you buy complete assemblies.

To clean and service the pilot assembly, remove the screws holding the front plate on where your control knob is. Once that is removed you can see the back of the ignitor, it is black and has one wire coming from it leading up to the ignitor electrode. You will also be able to see the small gas line from the gas valve going up to the pilot tower and the small copper line from the gas valve to the thermocoupler. That assembly is what you need to get to, to clean.

You do that by removing the top canopy by removing the three screws holding it down. Once that is removed, remove the center nut on the heat exchanger (the part that heats up with all of the little holes). It is located on the top and in the center of the heat exhanger. Then remove the three screws that are located around the bottom of the heat exchanger that connects the collar to it. You should be able to remove the heat exchanger now. Tilt the whole heater down and prop the neck on something so you can work on it.

If you look in the top you will be able to see small metal box covering the pilot assembly. This is held onto the pilot assembly with two screws. Remove those screws and carefully remove the box. Now remove the two screws that holds the pilot assembly to the collar (located on the outside of the collar). The gas and copper lines will hold it up. If you look at the pilot assembly from the top you will see one screw holding the ignitor electrode to the pilot assembly bracket. Remove that screw, unplug the wire from the ignitor and remove the ignitor electrode from the assembly. Be careful not to break this and I am having you remove it so that you do not break it.

Now remove the nut that holds the thermocoupler onto the pilot assembly bracket and pull it out of the bracket. The copper line will hold it up and be careful not to kink the copper line. Take a piece of sandpaper and clean the outside surface of the thermocoupler. Corrosion on the thermocoupler could cause it to fail which will cause the pilot not to stay lit. I have not had one do that yet but it could happen.

Now, remove the gas line from the bottom of the pilot tower so that the tower and bracket are in your hands. Put it down and put the heater back up straight. Hook up your gas and turn the gas on. Now, press the control knob on the pilot setting to make sure you have gas coming out of the gas line that feeds the pilot. You should be able to hear, feel and smell it. If not you have a regulator problem or an empty tank. Turn off your gas, remove it from the heater and tilt the heater back down.

Take your pilot assembly, you will see a circular top to the pilot tower that is held down with really small metal ears. Carefully bend the ears back so that you can bend the top of the tower back. Only bend it back far enough to clean the inside of it with a bent wire and compressed air or something. If you look on the lower side of the bracket, above where the gas line is threaded on you will see a hole that goes all the way through the assembly. This hole regulates the pilot gas pressure and allows the gas to mix with the air before it burns. Make sure that hole is clear of debris and take wire or something and thread it through the hole up through the top side of the tower.

When you have it clean, reconnect the gas line, thermocoupler and ignitor electrode. Once reconnected and before screwing the assembly back to the collar, I set the heater back up right and reconnect the gas. I then light the pilot to make certain you have a good strong pilot light generously touching the thermocoupler. The pilot should stay lit haver holding the button in for a few seconds. Do not turn the heater on past the pilot area without the heat exchanger on or you might singe your hair. If the pilot works the way it is supposed to, turn it off, disconnect your gas, tilt the heater back down and reassemble it following the intructions in the opposite manner.

The ignitor problem:
It is probably corroded in the cap (which is also the switch) or inside the ignitor where the battery goes at the spring. Spray these areas out with WD40 which will clean the corrosion out and try it again with a new battery. If it does not go click click click when you press the button you may have to take the ignitor out. Unscrew the cap and then the little black plastic collar which secures the ignitor to the collar. This should allow you to remove the ignitor by turning and maneuvering it out of the collar past the gas valve. Put the battery back in and replace the cap. Press the button to see if it works. Be careful it may shock you causing you to squeal, cuss and likely drop the ignitor.

I just had one do this to me. For some reason the little black collar that secures the ignitor to the heater collar would not screw all the way in. This would not allow cap to fully screw on and therefore would not allow contact with the battery to the contact inside the ignitor near the spring. Tighten it up as best you can so that contact can be made when you press the button. I believe this is one part you can order from Sunjoy separately if you cannot get yours to work....Good Luck

Pilot light wont ignite on patio heater


It may be that your cylinder is malfunctioning, cylinder has a leak, or the pilot is clogged. Please see steps below to troubleshoot. Note:Regular maintenance is critical to the successful operation of your patio heater.
  1. Is the cylinder valve closed? If so, open the cylinder valve but not fully.
  2. Check to see if you can light it manually. If the unit lights manually but not with igniter, service or replace igniter switch.
  3. Ensure that there is no air in the gas line. Open the gas line and bleed it (pressing control knob in) for not more than 1 - 2 minutes or until you smell gas.
  4. There may be a blockage in the orifice or pilot tube? Bugs and spiders get into the pilot assembly, venturi tube and burner ports causing the unit to either not light or poor performance.
  5. Is the regulator hose pinched or kinked?
  6. Cleaning the pilot assembly.
  7. If the piezo igniter won't spark to light the pilot, check the wiring to the igniter, It may simply have lost it's ground. Slide the wire off the igniter prong (looks like a thick needle) on the pilot assembly and then push it back on. That usually will reestablish the ground.
If you continue to have problems with the heater, contact Blue Rhino (the manufacturer) Customer Care 800-762-1142.

Hope this helps you to troubleshoot and solve the problem. Please let me know.

Have a Patio Heater that I purchased from Homebase last year. Model SRPH02A - looks similar to the coleman. Can not get it to light, Ignition sparks, bought new gas bottle - any suggestions please?


Spiders and bugs love these things - there will be something living in the pilot tube - have it cleaned by a pro, dont attempt it yourself.

Coleman 5040 Patio Heater w/ Light - Light works, Heater does not


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.

If you have a piezo ignition, then all you will hear is one click when you turn the knob. If I am guessing correctly, when you push in the knob and turn it, the gas flows to the pilot assembly, when you turn the knob far enough it will clilck and that sends the spark to the pilot assembly to light the pilot. Try turning the knob slowly before you get to the click, that will allow more gas to flow to the pilot. If this does not work, then you may have a blockage in the pilot.

Charmglow Patio Heater


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

Charmglow gas patio heater


Your thermocoupler seems at fault. The thermocoupler is that probe that sits in the pilot flame. It controls the main fuel valve. Make sure that probe is in the pilot flame, better at the tip of the flame and hold the button down for a minute or so after lighting the pilot. If pilot extinguishes, the coupler is faulty. If pilot stays on the heater should fire up when you let up on the pilot button.. 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.
