Similarly, it is asked, how does the switch on a gas fireplace work?

When the thermocouple is heated by the pilot light, it generates a very small electrical voltage (millivolts) which can be run through a switch to turn on a Milli-volt gas valve (as opposed to a 24 volt gas valve used with a conventional thermostat).

Similarly, why is my gas fireplace not working? Pilot light systems are the most common reason gas fireplaces fail to light, so check the main gas valve to make sure the gas is turned on. If gas is coming out of the pilot, but it still won't light, the spark igniter could be the problem. Look for and clear out any debris between the igniter and thermocouple.

Simply so, what does RS mean on gas fireplace?

Should the pilot light always be on in a gas fireplace?

Electronic ignition is when the pilot light on a gas fireplace/insert/stove is only running when the fireplace is on, this means that the unit is likely to have a battery backup as well. A standing pilot is always on, always using a small amount of gas to run constantly unless the gas is physically turned off.

Why does gas fireplace pilot go out?

If the pilot light on your gas fireplace won't stay lit, a very likely culprit is a component called a thermocouple. A thermocouple is a safety device and is a component of the ignition system. Its purpose is to not allow the gas valve to open if the pilot light isn't lit.

How do you replace a thermocouple on a gas fireplace?

Procedure for Replacing a Thermocouple
The only tool you need to replace a thermocouple is a wrench. Use it to unscrew the connector that holds the thermocouple to the gas valve, then unhook the probe from its clip and pull out the entire thermocouple assembly.

How do you adjust the pilot light on a gas fireplace?

How do you know if you have a bad thermocouple?

If you can't get the flame to light at all, and you're sure the gas is on, there's probably an obstruction in the pilot tube. If the flame lights and goes out when you release the gas control knob after holding it in for the recommended 20 to 30 seconds, that's the sign of a thermocouple malfunction.

What does a thermocouple look like?

The thermocouple looks like a piece of metal tubing smaller than a soda straw. To find it, first locate the gas control box. This is the box that the main gas line enters, where you turn the gas on in the furnace. The other end of the thermocouple sits in the flame of the pilot light.

How do you test a thermocouple?

Steps
  1. Locate the pilot light controls on the gas valve.
  2. Turn the pilot light on for 30 seconds.
  3. Release the button to see if the pilot light goes out.
  4. Turn off the gas supply to test the thermocouple again.
  5. Count to 20 and wait for the pilot light to go out.

How do you adjust a thermocouple?

To adjust the thermocouple, you must tighten the thermocouple nut with a wrench. Take care not to apply too much pressure to the nut -- just tighten it slightly. Then try lighting the pilot. If the pilot won't stay lit, replace the thermocouple with a new one of the same type.
