Gas Dryer Sounds Like A Blowtorch
Blowtorches make a real specific noise, whether they are the large commercial ones or the small culinary ones. So, if yous tell your dryer sounds like a blowtorch, everyone volition know what yous hateful.
The skilful tidings is that this really makes it slow to figure out if at that place is a job.
Gas dryers should not audio similar blowtorches. This is a sign that the gas is beingness released at overly high pressure. The about probable campaign is an incorrectly adjusted valve. To ready it, bring out the burner assembly too conform the valve to the manufacturer’sec specifications. Alternatively, it may be a faulty valve.
Some Noise Is Expected
Dryers are non repose appliances. Between the blowing air in addition to the spinning drum, there are going to live noises inwards the smoothest operation unit.
Gas dryers take the improver of the processes occurring in the burner assembly.

First, you have the whoosh of ignition. When the gas is starting time released too comes into contact amongst the heated ignitor, a mini explosion happens equally the gas catches fire. This sound is momentary together with might not even be real loud.
Secondly, you lot have the dissonance of combustion. All flames burn down amongst a dissonance. Whether or non you lot tin take heed the racket volition depend on the size of the flaming, how shut y'all are to it, in addition to what other noises are happening nearby.
With gas dryers, y'all are unlikely to hear this sound over the other noises of the dryer.
Finally, there is the sound of gas beingness released. This is a hissing sound and is produced every bit long equally the gas is entering the burner. If you are going to take heed a continuous sound from your burner assembly, this is it, as well as you may fifty-fifty liken it to a muted blowtorch audio.
However, a louder blowtorch dissonance is a sign that something is incorrect.
Blowtorch Noises Mean the Gas Pressure Is Too High
If your dryer starts to sound similar a blowtorch, then the about probable movement is that the gas force per unit area is too high.
Gas released nether greater pressure makes a louder audio.
In add-on, when the gas force per unit area is high, the charge per unit at which fuel is released by your dryer is greater. When besides much fuel is beingness released, the combustion reaction becomes less stable.
In other words, in that location is not enough oxygen for the sum of fuel beingness released, resulting in an wrong mix of air in addition to gas. This creates pockets of more flammable air too less flammable air.
Instead of igniting too burning continuously, the fire “jumps” from 1 bag of flammable air to the side by side, not burning the less flammable pockets. The initial ignition whoosh is repeated over and over.
Such situations are typically likewise characterized past a different colored flame. Typically, your gas dryer volition fire with a blue flame—peradventure amongst a flake of yellowish.
A flaming amongst besides much gas force per unit area will look nearly completely yellow. Unstable combustion is typically incomplete, which means that at that place is more carbon left over afterward the reaction. This leftover carbon turns the fire xanthous.

Often, the job is merely that the force per unit area valve on your gas dryer is prepare also high.
Problems With High Gas Pressure
If gas is released into the burner at an overly high pressure level tin can lead to multiple problems downwards the business if it is non addressed chop-chop.
For i, having high gas pressure level means that yous purpose more fuel than necessary. This, inward turn, way that y'all accept to pay for that extra gas. This tin add upwardly chop-chop over time.
More importantly, high gas pressure level can movement overheating in your dryer. When more gas is released, so more than gas is burned. This way more than heat is produced.
Over fourth dimension, the excessive rut in addition to force per unit area volition habiliment downwardly the internal parts of your dryer more speedily than would happen if the valve was correctly adjusted. This means that y'all would besides demand to pass coin to repair the internal parts or even supervene upon the entire car.
Fixing the Noise Should Be Simple
If your valve is prepare incorrectly, and then it is an easy process to suit in addition to cook.
To start, yous should plough off the gas to the dryer and likewise unplug it from any outlets.
To detect the valve, you lot volition likely postulate to access the dorsum panel of your motorcar. From there, you lot can locate the regulator. If y'all are non sure what the regulator looks like, y'all tin can bank check inward the owner’s manual.
The manual, the regulator, together with/or the dorsum panel should enjoin you what your gas dryer valve should be ready to. If they solely pass you the ideal force per unit area reading, yous can purpose a manometer (amazon link).
Adjusting the valve should be elementary in addition to self-explanatory when yous come across it.
If yous ask farther help, you lot should reach out to the dryer manufacturer.
Possible Alternative Cause: Faulty Gas Valve
Now, if your gas valve is adjusted properly, so there is an option campaign. Happily, all the run yous did to expose the gas valve is non wasted because some other movement of the blowtorch dissonance is a faulty gas valve.
This will live unable to regulate the gas catamenia into the burner. Thus, a faulty gas valve tin can likewise result inward gas existence released at excessively high force per unit area.
Problems With a Faulty Gas Valve
In addition to all of the previously stated issues associated with high gas pressure, when the valve is faulty, at that place are other problems that can arise.
Depending on what is wrong with the valve, the gas force per unit area can besides drop as well depression. The dryer won’t rut equally it should. It may non even ignite.
If this is the case, then your dryer is completely unusable since it would not be able to generate oestrus at all. This is because at that place is no fuel available for your dryer to consummate whatsoever combustion.
Replacing the Gas Valve
If you take a faulty gas valve, you will accept to supervene upon it.
You tin can hire a professional to supercede it for you lot. If you lot don’t know what y'all are doing, this is the safest route to have because you volition live working amongst both gas in addition to electrical components. Therefore, it tin live very easy to impairment yourself if you are not careful.
It is, all the same, a possible DIY task.
Before you offset, it is important to take a replacement valve that is compatible with your dryer. In improver, yous need to likewise turn off the ability to your dryer as well as shut off the gas earlier beginning.
You volition demand to locate the gas valve. To do this, you will probable require to take away the dorsum panel. However, the valve’second place is likely to vary depending on the dryer you lot have.
To remove the electric current gas valve, you lot volition take to purpose a wrench to loosen it carefully. Make sure to be cautious in addition to non damage whatever pipes or surrounding mechanisms.
You will then want to clean the fixture alongside a soft towel before installing the novel valve.
To complete, y'all will want to reassemble the residuum of your dryer.
Gas valve problems tin can besides effort the gas dryer to emit a whistling audio.
