I have had similar problems in the past when running out, what I found is I had to hold the pilot for several minutes to get the lines full of propane again. I found it easiest to light the stove top or try until it would burn then I went to the furnace and water heater it still took a few minutes as the pilot is a very small draw but once the lines had ...

My understanding of pilot lights is that they heat a thermocouple, which is a mass of metal that detects heat. The electronics behind that thermocouple will shut off the gas to the pilot if the thermocouple gets cold so that if something blows out the pilot you don't have a gas leak in your home. The side effect is that you have to heat up that mass of metal ...

With pilot switches, you can get any combination you want, simply by wiring it differently.
Top: the pilot is on when the switch/light is on.
Middle: The pilot is on always.
Bottom: The pilot is on when the switch/light is off. However, this works by leaking power through the bulb. So it only works if the bulb is not burned out, and is able to ...

Yes, either the thermocouple is going bad, it's not getting heated, or something is wrong with the controller. The most likely of those is that the thermocouple needs to be replaced. The button you press to light the pilot bypasses the thermocouple. When you release the button, the thermocouple ensures that unburned gas doesn't get released by shutting off ...

If there were a way to spark the pilot light automatically, you would not even have the pilot light at all (you would just use THAT thing to spark the flame only when needed). This is how my stove works: I have no pilot light, but I have "spark plugs" at the burners (they make a loud clicking noise when the gas knob is in the Start position).
So, by ...

According to online documentation, this model uses a glow bar. For an oven (not a stove top) one should NOT have to press any button to get anything to ignite - the thermostat and circuitry will take care of that for you, provided everything is intact and working.
If it were my oven, I'd open the door, remove the lower metal cover from within the oven (...

I experience this exact same problem (sparking throughout the entire cycle) when the 646AX gas valve assembly failed and had to be replaced. No direct replacement was available but the stated equivalent replacement was the EF32CW.
I soon found out that the EF32CW doesn't actually have true separate PICK and HOLD coils -- it just ties the two connections ...

I finally found some time yesterday to take a closer look at the furnace.
Gas Pressure
I started by measuring the incoming gas pressure using a gas pressure gauge. I found it to be 6 WC (inch water column), which is well within the acceptable range specified on the furnace.
Dirty Gap
Next I took a closer look at the spark gap itself, and watched closely as ...

To be clear for future searchers: the nut is critical, it provides half of the electrical connection.
A thermocouple requires two wires to function: electricity is generated at the junction of two different metals and two wires are needed for current to flow. While some thermocouples have two wires, the original poster is talking about a model with one ...

The new switch is just the same as the old switch except that the connection between the switch's load terminal and the hot side of the pilot light is internal to the new switch. This internal connection replaces the split done with the wirenut.
Here's how your existing switch is wired:
The single black wire is the Hot wire. The white wire is the Neutral. ...

In almost every case you have a gas valve with “pilot” and on yes the pilot stays on. This is normal, the quantity of gas is very small. The air in the line had to be purged and because the flow is low it took a while so none of what you described was out of line.
If it’s summer and you don’t plan on using the unit turn the gas to the off position with the ...

Blow into the gas pilot to unclog it.
Its definitely not a spider that crawled into it but possibly grease build up. You may want to consider fitting a gas oil filter for your system.

I reinstalled the pilot and cleaned out the burner and related assemblies and the pilot was only going out in the morning.
The issue turned out to be because we are still on a low-pressure gas system, which is susceptible to condensation and water seeping into the natural gas service pipes. The guys from my gas distributor pumped all the water out of the ...

The following is a sequence of operation for that style of Bryant/Payne/Carrier
furnace that
uses the three wire bimetal safety switch:
The thermostat calls for heat.
24 volts goes to the HOLD coil in the gas valve and to the 3-wire pilot switch.
The 3-wire pilot switch sends 24 volts out through the “cold” contact to the spark module that then produces the ...

Check the valve in the bottom 2 pictures that is connected to the pipe that comes up through the floor. That is the manual gas valve that may need to be turned if it is turned off. First, turn the knob marked off, low and high to OFF. Then, in the bottom 2 pictures, that RED knob or button that slants to the left and slightly downward will need to be pushed ...

It helps to have an understanding of how the gas control works. The gas control valve operates a solenoid-operated valve that delivers gas to the burners when your thermostat calls for heat.
The pilot flame should always be burning, and heating the thermocouple bulb that is situated adjacent to the pilot flame. The thermocouple feeds a signal via a thin ...

I also believe you don't have an electronic spark ignition and a pilot. Although I don't have a thermostat, I do have a light switch which will turn on my logs burner. I suspect your thermostat turns on your burner. Suspect that your gas valve does have a pilot and therefore, a push-and-hold requirement to light the pilot because there is a safety ...

Once you light the pilot hold it there for up to a minute then turn to on.
It is possible the thermal pile or thermocouple is not quite hot enough.
I find giving it a minute usually works if it still goes out and the flame is hitting the probe of the TC it is time for a new one.
The good thing is they are inexpensive and easy to change.

A 100lb tank? In Winter? In Maine? You are almost certainly overdrawing the tank.
Liquified Propane has to boil to provide you with gas, and it takes heat to do that. The pressure in a propane tank is a direct reflection of the temperature of the propane tank, and they will cool to well below ambient temperatures when boiling hard to meet a high gas demand. ...

The thermocouple needs to be screwed tightly into it's socket. And the pilot flame needs to be fairly robust. If the pilot is weak it will not maintain enough heat to sustain the electric voltage necessary to hold the valve open.

Something to look at is the pilot flame itself. It is often adjustable by removing a small screw cover marked plt.adj. or something similar. The thermocouple should be fully immersed and the flame should not be lifting.

This is an Empire style wall furnace. It does not need electricity. You'll be glad for that later.
The twisty valve is designed to completely shut off gas flow if it doesn't feel heat from the pilot light. This is a safety feature designed to keep your apartment from filling with gas and exploding. You will find this kind of safety feature on many ...

There are detailed instructions on the water heater, text and diagrams, but the following is my recollections.
If the gas tap at the end of the house supply piping is turned off, the knobs on the heater will be in the operating positions.
Turn the main control on the tank off and then turn it to a position that will be labeled "Pilot". (Maybe just turn it ...

These 3-wire assemblies are crap. They sometimes act as you've described, other times they spark and never ignite the pilot. You can try taking the assembly out and cleaning it up, or just replace it.

I realize this is an old question, but it's hot once again and the question may come up for someone else.. so I thought I'd venture an answer. I don't work as a heating/cooling professional, I'm just a homeowner.
Your plumber may be right, and from my experience, it is uncommon that he'd know that (unless, like you said, he was trying to get the home ...

If their is a good flame on the thermocouple then it is a bad gas valve. Sometimes if the gas valve is just barely bad a hotter thermocouple will work for a short time but finding a hotter thermocouple is just hit and miss. I have seen people try 4 thermocouples and the fifth one worked then they claimed the other four were bad. The furnace of course stopped ...

You should properly repair the problem. You are dealing with gas, there is some risk in that. You're also burning your time messing with it so often.

Standard gas log sets are fairly simple. If the gas fireplace shuts off after a few minutes, it's pretty much always going to be a pilot head issue, or a valve issue. Take note that it’s the pilot head, not the thermocouple. The whole assembly is usually replaced, and they usually come at the same price. New models usually come with improved designs.
It is ...

Check to make sure the wiring for the flame sensor is properly connected, and the wire is not damaged. If that all seems good. Replace the flame sensor. If the pilot is not proving, it's almost certainly because the flame sensor is not detecting it.
Flame sensors do go bad, but are typically a cheap replacement. However, it looks like the sensor in your ...

The problem ended up being my gas supply. I was sure the thermocouple was installed properly and the whole assembly was cleaned properly as well. The other thing being that the pilot would always go out in the morning and would be fine during the day was another reason.
I called my gas distributor and they sent out some guys to pump the water and ...
