Solved! Pilot Light won’t Stay Lit When I Release the Knob Here are the 6 Reasons

Pilot light won’t stay lit when i release the knob is an general problem found in the pilot light/gas furnaces. If you found such problem in your furnace then you are in the right blog.In this blog we will tell you what is the problem in your pilot that won’t stay lit when you release the knob. Before discussing the problems first understand the mechanics of pilot light after that you can easily understand the article point that why pilot light won’t stay lit when i release the knob.

Pilot Light Mechanics

A furnace’s pilot light is found between the two portals on the main gas valve. When the pilot is in operation, an adjacent thermocouple faculties the warm and keeps the primary portal open,in this way permitting the pilot to stay lit.. When the pilot light is off, the thermocouple cools back and transmits a indicate to the gas valve to close the first portal. This keeps fossil gas from flowing out into the air of your home.

Few furnace issues are as frustrating as a pilot light won’t stay lit when i release the knob because this problem seems like it could be so easy to fix. So now, with the right knowledge, the issue may indeed be an easy one. If you would like to learn more about troubleshooting a pilot light won’t stay lit when i release the knob, read on 6 major problems why pilot light won’t stay lit when i release the knob.

• Button Override

On the gas valve there is a knob that must be pressed when reigniting the pilot light. This knob simply works as a manual override of the first valve portal. In other words, when you depress the knob, gas starts gushing to the pilot, permitting you to light it with a long match or lighter.
Here is where issues often appear. If you release the pilot knob too quickly, you may find that the pilot stammers and goes out. Because the thermocouple does not have enough time to heat up. Unless it reaches a certain temperature limit, it will not send the indication to keep the valve gate open. In future you try reigniting the pilot, make sure to keep the knob depressed for several seconds while the thermocouple warms up.

• Kinked or Clogged Pilot Tube

It causes problems in pilot light, if a kink or clog in the pilot tube will prevent the gas from flow.

• Remove the tube from the pilot termination.
• Blow condensed air through the tube to remove any blockage.
• There could be a choke in the orifice of the pilot cessation.
• Do not use a needle to try to remove the choke as the needle may unintentionally expand the hole.
• If you’re unable to remove the choke, replace the entire assembly.

Gas Off or Low Inlet Pressure

Check that the handle of manual gas valve is in the same direction as the gas flowing. It’s called on/open position.Also check that the knob of pilot on the gas valve is rotated to the pilot position. This can be affirmed by pressing the knob down completely. Another issue could be that the manual valve on the natural gas metre could be shut off too. However another issue could be that the propane tank is purge. You can check to see at the gauge to verify how much propane actually is available.

A Dirty Thermocouple Rod

The carbon dust created by the flame will insulate the rod from the full heat generated or carbon deposit may build up on the end of the thermocouple rod.This build up acts like an insulator.
To clean up the carbon off the rod, use non-soaped steel wool.
Avoid using sandpaper or any other substance that will use a remnant on the rod.
Make sure none of the steel wool gets inside to prevent a clog inside the pilot tube orifice at the pilot termination head. You can clean up the rod by pulling out from the unit.

Your Gas Regulator is Faulty

Your gas regulator acts to reduce the pressure of the natural gas that’s provided to your home. You can typically find the regulator at your gas metre. Check to see that the gas regulator is old or invalid.If YES, then gas may not flow through it at a stable adequate pressure to support your furnace’s pilot light.
If your gas regulator is invalid, you’ll also observe pilot light problems on your other gas-powered appliances, like your clothes dryer or water heater.
If yes, Call the concerned person/department to fix the issue.

A Broken or Damaged Thermocouple

In this case, something goes wrong with that equipment and a concerned person/technician would be required to replace/repair the thermocouple in order for your pilot light to stay lit. If your pilot light remains to go out again and again, and you have tired all other possible causes, you have to replace that assembly.
