How to Get Patio Heatre Woorking Again
We love sitting out on the patio under our propane heater in the evenings, but lately, information technology's get a bit difficult to low-cal. What's the main cause of this?
Propane patio heaters usually do not lite due to a dingy thermocouple (the temperature sensor) or a muddy airplane pilot light. This can be solved with a elementary bit of cleaning rather than having to buy new ones. Yous also need to check if y'all've run out of propane, which is surprisingly like shooting fish in a barrel to practise.
Allow's swoop down into this field of study in more than detail, and observe the main causes of propane heaters failing to light, and what you can practice to finish it happening in the futurity past keeping your heater cleaned and well maintained (unlike ours!)…
What Causes a Propane Heater Non To Light?
There are several reasons why your propane heater is failing to ignite. Most often, information technology's due to a problem with the thermocouple (the temperature sensor) or the airplane pilot calorie-free. This can ofttimes be remedied with a simple bit of cleaning, and we'll expect into this presently.
An even simpler reason is at that place might exist a chip of a breeze, which is bravado out the airplane pilot low-cal. As your patio heater is, naturally, on the patio, it's not unlikely that there's air movement.
The igniter is also a potential consequence. The easiest way to test whether the ignition is the source of the trouble is to grab a stick lighter and light the heater manually. If this works, then the igniter may be dingy or worn out.
Also, cheque the valve and the hose between the propane cylinder and the heater. A muddy or blocked valve or a kinked hose will foreclose the gas from coming through.
And we hate to sound patronizing, simply we all ever need to check this i… Have you run out of gas? That last bit of propane sure seems to run out chop-chop!
Another potential issue is the exterior temperature. Propane doesn't like existence below twoscore degrees, and your heater won't work at these temperatures.
So, nosotros're sorry, but there are a few things that yous'll need to cheque if your patio heater isn't lighting. On the vivid side, at least there are lots of fixes to try before you surrender on your old heater. We'll take a closer look at troubleshooting and solutions.
How Can I Clean The Igniter On My Patio Heater?
The igniter (or sparker) can be the cause of the problem. There's a simple way to examination for this: try lighting the heater manually with a stick lighter. If this works and the burner ignites, then the igniter is at fault.
These practise get worn out with time and use, and they're easy and cheap to replace. You can pick up a universal igniter online, or contact your patio heater'due south manufacturer if you want to stick to the brand's spare parts.
You could always try cleaning the heater first. Disconnect the gas and remove the emitter screen, and then gently employ a harbinger brush or (preferably) compressed air to dust the within. Never apply a damp fabric, equally the parts demand to remain dry.
How Do I Test My Patio Heater Igniter?
If your propane patio heater won't light, there may be a problem with the igniter. Most patio heaters have an igniter, which is also known as a spark igniter or a sparker. This is a minor electrode that ignites the pilot light.
To test whether your igniter is the problem, attempt lighting your heater manually using a stick lighter. (If you oasis't got one, a match will practice, although be extra-careful with your fingers in case the burner springs into life…). If the pilot light ignites when you utilize a manual lighter, so the trouble lies with the igniter.
You can then take a closer look at the sparker. Remove the emitter screen (this is the screen around the master burner, and information technology'south usually easy to remove using a screwdriver). You lot tin can now get a proper look at the ignition assembly.
This is fabricated up of the sparker itself, the airplane pilot tube, and the thermocouple. You can advisedly concur downwardly the ignition switch and look out for a spark. No spark? It's time to option up a new igniter, an inexpensive part that is pretty easy to fit yourself.
How Exercise You Clean a Thermocouple On a Propane Heater?
The thermocouple is the temperature sensor on a propane patio heater. Similar any sensor, if it'southward not working properly, it can finer stop the whole arrangement from functioning. If the patio heater ignites OK just then won't stay lit, information technology could exist considering there's a trouble with the thermocouple.
The thermocouple is a simple copper rod that's located next to the pilot tube, and together with the sparker, forms the ignition assembly. Information technology's a safe feature, and its role is to halt the gas flow if it doesn't observe the pilot light, preventing gas leaks.
The thermocouple can easily get dirty, and this is usually caused by a build-up of carbon from the propane. This carbon coating covers the sensor. Considering it tin can't sense the pilot low-cal through this layer of clay, it assumes that the pilot calorie-free has gone out, and and so shuts downward the whole thing. Arguably, it's still doing its job, only non in the way we want it to!
Luckily, the thermocouple can be cleaned. Disconnect the gas and remove the emitter screen (typically, this is held on with but a few screws). Again, you need to make certain that the inside of the patio heater stays dry. Use a small brush to clean abroad the carbon layer.
But what if this coating is too built up to remove with a brush? If yous're super-careful, you can use a small molar file and lightly sand the carbon from the surface. Still not make clean? It may be time to invest in a shiny new thermocouple for your heater.
Here's a brusque (and strangely relaxing) flick nigh how to alter the thermocouple on a patio heater.
How Do You Test a Patio Heater Thermocouple?
How do you found whether the thermocouple is the problem? Well, if you think it may have a buildup of carbon that's preventing information technology from working, have the emitter screen off and have a good look at it.
But what if it looks perfectly make clean, and the patio heater still isn't staying lit? You'll need to bank check that the thermocouple is in the right position.
The thermocouple works by sensing the heat from the pilot lite. If information technology can't sense this, it shuts down the heater past preventing the gas flow. Sometimes, this small copper rod tin get dislodged (especially if information technology'south a portable heater and you've been moving information technology around) and moves away from the airplane pilot light.
Now, the thermocouple is no longer close to the pilot light, and can't sense its estrus. It does what a good sensor is meant to practice when it is triggered and closes downward the organisation. The result? The heater ignites, then rapidly goes out again.
This can exist a really quick gear up. Switch off the gas and take off the emitter screen. Loom at the ignition assembly. Does the thermocouple seem to accept moved, or look like it'south a long way from the airplane pilot tube?
Using a small pair of pliers, gently squeeze the thermocouple closer to the pilot tube again. This really is a simple fix.
Merely bear in mind that there could be other reasons why the gas isn't reaching the heater, such equally a leak or twist in the hose, a chock-full or faulty valve, or the gas has simply run out.
How Practise I Reset My Propane Heater?
After you've replaced an empty propane cylinder, you'll demand to reset your patio heater. Later on you lot've removed and replaced the empty tank, you'll need to brand sure that the pilot light is working safely again.
There should be a knob inside the heater that has a Pilot position. Push this in, then low-cal the pilot using the igniter, as you usually would. Hold the knob in for about half a minute, which gives the thermocouple fourth dimension to start working.
Release the knob. Has the pilot lite stayed on? If information technology has, you're back in business organization. Savor the cozy warmth on your patio.
Concluding Thoughts
So it looks similar all our patio heater needed was a good clean of the thermocouple and the pilot light, so we could become that propane flowing through it again and light it.
This is a fleck of a lesson for me actually – and it serves me correct for just leaving our heater outside for too long without cleaning it properly.
Oh well, nosotros live and learn! 🙂
