My furnace keeps making an explosion when it ignites

The amount of gas buildup is too great. Make sure the burner ports are clear right next to the pilot light area. - run a small wire into the holes to make sure they are clear then make sure the pilot light is burning into the area next to the burner. A bit of whoosh is to be expected but if it becomes too great it will blow the pilot light out. Sears wall furnaces are prone to this the burners have to be kept clean

Kozy world propane wall heater pilot will not light

This can be caused by several things:

1. The inline gas valve running to the the heater is OFF. Turn the valve ON.

2. The gas control knob on the heater is not exactly in the PILOT position. Unless the knob bottoms
out and you feel strong pressure (other than spring pressure) pushing back at you. It's not exactly
in the PILOT Position. Once the pilot lights, hold the control knob in for 30 seconds to 60 seconds
to allow the Thermocouple to full heat.

3. The pilot is dirty and needs to be cleaned, as do the burners.*

4. The LP Gas Tank is empty or to low to maintain te proper gas pressure.

* Here is a link to a demonstration on how to properly clean the pilot & burners.

I hope this helps you to troubleshoot & solve the problem. Thanks for choosing FixYa.

I have a few issues with an old probably dinosaur Coleman Presidential III 7995a-856 Heating unit. I've had 3 different repairmen look at it and they're clueless. The main pilot will light and stay lit...

if the pilot is clean and and strong then this should play on to the thermocouple , i take it you have changed the thermocouple , and the connection is good at the gas valve , then if this going out could be 1, powerunit on gas valve not holding at thermocouple connection

2. Hole in heatexchanger blowing out pilot when blower comes on

I take it the pilot stays on untill fan comes on and keeps going out , I would think about not putting any more money in to this and get new if sounds as the heater has had its day ,

My pilot light ignites but when you turn the knob to light the burner it goes out?

Your pilot generator may be the cause. They tend to get weak and will hold the pilot but won't be strong enough to operate the gas valve solenoid. All space heaters have some sort of thermocouple device in the pilot that hold the gas open as long as the pilot is lit. Some simply hold the gas valve open while others called millivolt valves use a pilot generator to operate the solenoid. Another type of heater is an ODS type. This system has a oxygen depletion pilot safety feature. When oxygen gets low the pilot shuts down the gas. If this is what you have then all you need to do is blow the dust out the pilot and it should stay on.

When I light the pilot light, the heater comes on, but when it reaches a certain temperature and turns off, the pilot light goes out. Please explain very simply, I am not mechanical.

It could be a number of problems, so let's start with the easiest! When you light the pilot, is the pilot flame a strong blue color or a lazy yellow color? If it's yellow, it may not be heating the thermocouple sufficiently to keep it lit after the burners reaches temperature, so it shuts off with the burner. The solution is to clean the dirty pilot orifice using a can of compressed air with the straw attached (the kind you use to clean computer keyboards) With the heater pilot turned off, blow air down the flange where the pilot flame burns. If it has an air hole on the side of the pilot assembly, blow air through that too. Then relight it and if you have a blue pilot flame, see if that solves your problem and stays lit through the entire cycle. If not, go to the next problem:

You may have a dirty flame sensor bar. if your heater is so equipped, there is an small "L" shaped bar that protrudes near the end of one burner and senses the burner flame. carefully clean it using a small piece of sandpaper, being careful not to put too much pressure on it which might break the porcelain piece on the other end. Then wipe it clean with a dry cloth or paper towel and try lighting it again and see what happens. If that doesn't fix it, then try this:

It is also possible you have a defective thermocouple. Typically when they go bad, they won't stay lit at all, but sometimes they do light and go out later. Solution: Replace the thermocouple. It is the skinny metal bar that the pilot flame is heating. It is screwed into the gas control on the other end. Make sure it is cooled down before pulling it out of the pilot assembly. Don't worry, it doesn't have gas coming out of it and there is no electricity connected to it. Remove it and measure it and take it with you to the nearest hardware store or do-it-yourself center and they will match one up for you.

Other possible problems could be a strong draft blowing in the vent and blowing out your pilot, so make sure you have a vent cap outside. Or it could also be a blocked outside vent that is causing it to shut down, so check for blockage via a bird nest, dead bird, wasp nest, etc. Hope these help!

Let me know if you need more info or if one of these works for you! Douglas

My patio mushroom heater lights up ok but keeps going out by itself after about 5 to 10 minutes and then can be started again inatantainiously by starting pilot light and away you go until it goes out...

Here's a few things to check. When you light the pilot, is it a strong blue pilot flame, a weak blue flame or a lazy yellow flame? Is it heating the thermocouple enough to make it red hot after a few minutes? If the pilot is small blue or lazy yellow flame, it may be dirty and need cleaned. When the burner lights, the weak pilot flame may diminish causing the thermocouple to cool off enough to shut down the main burner. Clean the dirty pilot orifice by using a can of compressed air with attached straw. (The same canned air you use to clean computer keyboards) Blow it into the pilot assembly where the pilot flame burns out from and blow thru the air holes on the side, if applicable. You might also check the thermocouple itself to make sure the tip is not partially burn't off. It should be a smooth, rounded tip. Replace the thermocouple if cleaning the pilot orifice doesn't solve the problem. Douglas

There is a thermocouple "wire" that is supposed to be touching the pilot flame.
The thermocouple senses a flame (hot) and allows the heater to operate. If the thermocouple does not sense that the pilot is on, then it will not allow the furnace to operate.
Bend the thermocouple wire (or the pilot tube) so that the pilot flame is touchingg the thermocouple.

That shouls work now.

The air from the fan should not be blowing through the same cxavity that the pilot is in.
If it is, then you may have a leaking furnace whereby carbon monoxide may be seeping into your living quarters.
If the fix above works and the pilot stays on after the heater starts, then there is probably no leak.

Let us know the results ... post a comment or "RATE" this or another expert's solution.

The pilot light will not stay lit to light the heater.

The power pile (pilot generator) is defective. It produces a milivolt signal to ensure to keep the gas valve open. If it goes bad, the valve thinks the pilot is out, even when you are holding the button down, so when you release the button, it shuts the gas off to prevent excess gas buildup and a possible explosion.
