How to Replace the Thermocouple
- Turn off the gas and make sure the pilot light goes out.
- Wait twenty minutes for the thermocouple to cool down.
- Loosen the screws that hold the thermocouple in place.
- Pull the thermocouple out with long nosed pliers.
- Put the thermocouple on a surface that will not burn (just in case).
- Clean the screw terminals.
- Insert the two wires of the new thermocouple and tighten the screws.
- Turn on the gas and re-light the pilot light.
- Wait a while and then turn on the fire. If you have replaced the thermocouple correctly the fire will light.
- Thermocouples need to be checked regularly but replacement is the only option for repairs.
How to replace a thermocouple on a gas stove?
To replace the thermocouple, you will have to remove the front panel from the gas stove, and also lift the top cover with rings on it The working tip of the thermocouple is rigidly fixed near the burner or burner with a nut. If it cannot be unscrewed due to scale, then it is not worth putting pressure on the key. So you can only break the mount.
How do you bypass a switch on a pellet stove?
With all of these switches the process for bypassing the switch is the same; unplug the pellet stove, disconnect the wires from the switch, connect them together and plug the pellet stove back in. Spade connectors can slide onto each other and will stay. Other connectors you may need to tape together.
What are the different temperature switches on a pellet stove?
Also known as a Snap Disc, Low or Hi limit sensor, proof of fire, or Temperature Sensor; every Pellet Stove has at least one if not more of these switches. Most stoves have at least a Low Limit and Hi Limit Sensor and some have a Convection Fan Temperature Switch.
How do you turn on a convection fan on a pellet stove?
A Convection Fan Switch is usually mounted to the back of the firewall of the pellet stove and has two wires going to it. Most Convection Fan Switches turn on/off at 200 degrees Fahrenheit. The switch is normally Off or Open and turns on when the stove gets hot enough which turns on the convection fan.
How do you test a pellet stove thermocouple?
The simplest way to test a thermocouple is to check how much voltage it produces. To complete this test, you will need a digital meter that can measure millivolts (mV) of DC electricity and a lighter. Remember to unplug the stove from the wall before disconnecting any wires.
What is a thermocouple on a pellet grill?
The thermocouple is the instrument that measures the interior temperature of the pellet grill, and is located on the back wall of the firebox.
How do I know if my pellet stove thermocouple is bad?
If you've checked all these things and the snap discs and vacuum switches are good, then usually it is most likely a bad thermocouple. Look for what Quadra-fire calls the amber colored light on the clear control box of newer pellet stoves. It is a yellowish color. This indicates a thermocouple error.
Why does my Quadra Fire pellet stove keep shutting off?

Top Reasons Pellet Stoves Shut Off It's dirty: If the unit is dirty, it can cause the stove to have trouble actually getting the fire going. You should keep that in mind and then clean out your unit ASAP. Minimal air adjustment: This means that the sensors cannot get enough heat transmitted to them.
What does the Traeger thermocouple do?
The thermocouple communicates the grill's temperature to the controller, which will display the temperature on the screen as well as determine the speed the auger motor should feed pellets to maintain the desired temperature.
What does thermocouple measure?
What is a thermocouple? A thermocouple is a sensor that measures temperature. It consists of two different types of metals, joined together at one end. When the junction of the two metals is heated or cooled, a voltage is created that can be correlated back to the temperature.
Why is my Traeger dropping temperature?
Yes! It is completely normal for your Traeger's temperature to rise and fall throughout your cook. Traeger grills cook on an average. This means the temperature will rise above and fall below the set temperature throughout your cook, but the average temperature will still be your set temperature.

The thermocouple tip is located directly next to the hotplate and gas fire.
How many mV does a thermocouple need?
And this is already enough to control the electromagnet that controls this or that shutter. Thermo-EMF in most varieties of thermocouples for gas stoves reaches 15–30 mV, and usually 5–10 mV is enough to keep the electromagnetic valve in the open state.
How does a gas stove ignite?
The gas in the burner of the stove is ignited by matches, a manual piezo-lighter or built-in electric ignition. Then the flame should burn itself without human intervention, until the fuel is shut off by a valve. However, often the fire on the gas hob or in the oven goes out as a result of a gust of wind or a splash of water from a boiled pan.
What is the simplest temperature sensor?
A thermocouple is the simplest temperature sensor without any electronic devices inside. There is nothing to break in it. It can only burn out from prolonged use.

How to remove thermocouple from stove?
6. Remove the thermocouple from the thermostatic valve connected to the stove burner by unscrewing the hex nut of the thermocouple with a small crescent wrench. If you have a thermocouple connected directly to the burner, loosen the hex nut that holds the thermocouple in place. Lift the old thermocouple off of the thermostatic gas valve.
What is a stove thermocouple?
By Alexis Rohlin. A stove thermocouple is made out of two dissimilar metals that create an electrical charge when heated by a burner flame. The electrical charge flows to the end of the thermocouple to power an electromagnet that controls the gas valve, also called the thermostatic valve. The electromagnet holds the valve open when electricity ...
How to remove the front face of a gas stove?
Remove the front face panel screws, located on the top front edge of the burner tray with a Phillips screwdriver. Remove the screws on the top side edges of the burner tray. Pick up the tray and set it aside. Beneath the tray you will see the burner housings and the attached thermocouple. The thermocouple is a small nozzle like device that may be connected to the gas valve with a brass fitting or connected directly to the metal housing of the gas burner on the stove top.

What does it mean when you smell gas after replacing a thermocouple?
Warnings. If you smell gas after replacing the thermocouple, there is a leak in the stove's gasline. Turn of the gas at the main gas line shut off valve, which is located near the gas meter on the outside of your home. Contact at repairman or your utility company and get them to fix the leak before using your stove.

Pull the spade wire connection (if any) of the thermocouple, located under a plastic cap on the back side of the gas valve, up and off of its connection.
Why does my stove smell gas?
If you smell gas after replacing the thermocouple, there is a leak in the stove's gasline. Turn of the gas at the main gas line shut off valve, which is located near the gas meter on the outside of your home. Contact at repairman or your utility company and get them to fix the leak before using your stove. Failure to do so can lead to catastrophic injury, as propane is highly flammable and can ignite or explode.
How to bypass a pellet stove switch?
With all of these switches the process for bypassing the switch is the same; unplug the pellet stove, disconnect the wires from the switch, connect them together and plug the pellet stove back in. Spade connectors can slide onto each other and will stay. Other connectors you may need to tape together. Or some people prefer to jump the wires together without taking them off the switch. You can jump the wires with a paper clip, a wire or preferably a jumper wire with banana clips.

Why Gas Stove Thermocouple?
Device and Principle of Operation
- The thermocouple is based on the Seebeck thermoelectric effect. According to him, at the ends of series-connected conductors of different metals, provided that their contacts are at different temperatures, a thermo-EMF (TEMF) occurs. That is, it is necessary to have two conductors of different composition that can withstand strong heating, and high-temperature heat (in this case…
Varieties of Temperature Sensors For Gas
- Thermocouples of gas stoves differ in the alloy of conductors and the type of connection to the valve. And the main thing here - each manufacturer of gas equipment uses its own versions of electromagnets with different connection sockets. In most cases, it is impossible to rearrange the thermocouple gas monitoring sensor from one tile to another. Alloys and metals for creating the…
