SOURCE: Propane patio heater ignition problem

I would change the thermocouple and here is why:

The thermocouple is the pilot's, well, co-pilot! It is the electronic device that senses if the pilot flame is hot enough to sustain burning the gas fuel from the burner. If the thermocouple thinks it's safe, then it keeps open the main gas valve located in the pilot assembly. If the thermocouple does not sense enough heat from the pilot flame (such as when the pilot is out), then the thermocouple shuts off the gas valve to the burners.
How the Thermocouple Works
So what is this thing and how does it work? Well the thermocouple (technically called a thermocouple junction) is a device that contains two metal wires welded at the ends and placed inside a protective metal case. The thermocouple sensor is found at the business end of the pilot flame and is designed to be placed in the hottest part of the flame. The other end is connected to the pilot valve body. As the thermocouple heats up, it produces a small amount of electricity and when it gets hot enough from the pilot, send a signal to open the gas valve by using a solenoid operated by a 24 volt transformer. The thermocouple calls the shots, and by converting heat to an electrical signal, it allows the gas valve to open or close. Once the gas valve is open, gas is then constantly supplied to the pilot and as required for the gas burners (as called for by the thermostat). If the pilot goes out, then the thermocouple gets cold and produces no electric signal to open the gas valve's solenoid and the gas valve shuts off the gas supply to the pilot and burners

The main burner valve is the oven valve. The pilot will be next to the burner and you either have to insert a long shiskabob stick ( lit) into the hole or lift up on the bottom of the oven (inside) and you will see the pilot.

Light pilot reset

If yours is a high-efficiency furnace, you should hear the stack blower start running when your thermostat calls for heat. Next, the igniter should start to glow and remain glowing until the thermocouple opens the gas valve and allows gas to flow to the main burner. The main burner lights and burns until sufficient heat is generated for the main blower to turn on and blow warm air through your house. If any action does not occur in the order described, repairs are in order.

Pilot light doesn't stay lit

The thermocouple may have failed. It looks like a copper wire that goes from the gas valve and leads to the pilot light.My first thought is that the pilot light burner is not burning hot enough because its got dust in it or a spider web blocking some of the air it needs to burn hot. If the pilot stays on long enough to bring the main burner on, a dirty main burner lighting rough will cause the pilot to snuff out. To do the actual repair I would suggest that you contact the manufacturer on the internet. Getting up to your elbows in a gas appliance without professional help is asking for dangerous serious trouble. Good luck.

Napoleon Fireplace propane Pilot won't light main burner even though gas flows in?

  • I'm going to assume your fireplace has a pilot light.
  • Follow the little holes in the burner that lead to the pilot light.
  • Make sure the pilot flame is pointing directly at the closest burner hole. (adjust if necessary).
  • Often, you will need to sprinkle a layer of "glowing embers" in this area. The embers will help the gas travel to the pilot light and ignite.
  • Always start your propane appliance on "High" never "Low". Cold propane likes to drop to the bottom of the firebox and accumulate until it reaches the pilot (this is called delayed ignition). Keeping it on "high" will help the fuel travel over to the pilot without buildup.

Tappan 32-1272-10/07056-8509-4080 gas range/oven pilot light works,main oven burner won't come on

You will need to look and see if the igniter is glowing a bright red. If it is weak, the oven will not light. Here is the igniter if you need to order it.

Also check and make sure your getting 3.2-3.6 volts AC to the valve.

My Maytag gas dryer, Model No, LDG7500AAW will run but not heat. The igniter glows red, but the gas will not flow. What might be wrong?

Replace the 2 burner coils ,if the igniter keeps cycling trying to start the flame. If it doesn't replace the flame sensor mounted on the side of the burner tube.

Most modern ovens today, do NOT have pilots--
They have an ignitor that glows bright , and then the gas valve opens, and the burner lights.

Have you noticed when the Broiler burner lights, if you get a bright light from its ignitor?

You should see the same for the main oven burner, when you start it.

If not-- you need a new ignitor. Do you have any warranty with your oven?-- How old is it?

When you check these out, let us know, and we;ll help you to the next step

Possibly the ignitor for the main oven burner has failed--

An observation question:

When the Broiler 'lights' and comes on, do you notice the ignitor glowing bright, before the gas valve (to the Broiler) opens, and you get the Broiler lighting---

Now-- for the main burner to come on, -- there has to be a similar bright glow from the MAIN BURNER ignitor, before its main burner gas valve can open-- No Ignitor?-- No ignition, and not Main Oven burner!

Let me know what you need from this point on --

Oven wont light, pilot is lite but the burners wont ignight

Bakers Pride used several different safety valves over the years. If your oven has a pilot valve that has a beige know that you hold in and turn to light the pilot, then after it lights you need to turn the beige know another half round to the "on" setting. If you push in a red button to light the pilot, it may not be getting enough heat on the thermocouple where the pilot flame should be heating it up. Be sure the main gas valve on the front of the oven is turned to the on position also. On some models the pilot will light with the main gas valve in the off position. If you look at the pilot flame while it is burning, make sure that it is hitting the pencil sized thermopile enough to make it glow red. If not bend it slightly to improve the heating.
