Are All thermocouples for a water heater the same?
From an operational perspective the thermocouples for a water heater are all pretty much the same. However, there are two variables, the length and the fittings used to install them, see below. A failing thermocouple will not send the correct electrical impulse and the gas valve will not release any gas.

Can you use a thermocouple on a left hand fitting?
They make and adapters that will allow you to use a standard thermocouple on either a left hand or right hand fitting. A plumbing supply store should have the adapters available. Most 'Universal' thermocouples include adapter kits along with the thermocouple. This is the best choice in most situation.
How does a thermocouple work?
A thermocouple uses two types of metal to create an electrical current that the gas valve can sense. If the electrical current is transmitted, it means that the end of the thermocouple is hot and there is a flame. Simple right? Don't go looking farther than this for an explanation, this stuff can get pretty techinical.
Are thermocouples interchangeable?
Precision Ceramics' Materials in Thermocouples Commercial thermocouples are interchangeable, economical, and supplied with standard connectors. Unlike most other temperature measurement devices, external form of excitation is not required for thermocouples because they are self-powered.
Are all thermocouples universal?
When purchasing a replacement thermocouple or flame sensor, it's essential to make sure that it's compatible with your particular furnace model. Honeywell, White Rodgers, and other manufacturers make universal replacement thermocouples, usually with a 30-millivolts (mV) rating for standing-pilot furnaces.
How do I know which thermocouple to buy?
How to choose a ThermocoupleDetermine the application where you will use the thermocouple sensor. ... Determine the temperature ranges the probe will be exposed to. ... Determine how important a fast response time is. ... Consider any chemical, abrasion or vibration resistance. ... Consider any installation requirements.
Does water heater thermocouple length matter?
The length of a thermocouple has no effect on its measurement accuracy or its ability to transfer the signal to the instrument. In other words, thermocouples do not experience “voltage drops” or power loss along its length as a high current power line might possess.
Can I bypass a thermocouple?
Realistically, you have just disabled the thermocouple, but you can also reach in and unclip it from its holding bracket where it meets the pilot light. In most cases it will be held on with a gravity clip, but some are held on with a screw that must be removed with a small screwdriver.
Can I replace a thermocouple myself?
It's easy to replace and a new one costs $5 to $10. Rather than trying to unfasten the thermocouple inside the water heater's burning chamber, it's easier to remove the whole burner and thermocouple assembly.
Should I choose a type K or type N thermocouple?
Type N Thermocouple (Nicrosil / Nisil): The Type N shares the same accuracy and temperature limits as the Type K. The type N is slightly more expensive. The type N has better repeatability between 572F to 932F (300C to 500C) compared to the type K.
How do you know if your water heater thermocouple is bad?
If the pilot lights but the flame goes out as soon as you release the button after holding it for 60 seconds, then the thermocouple is bad. It's possible to replace the thermocouple without removing the burner assembly, and many repair people do this.
What makes a thermocouple go bad?
Soot buildup on the thermocouple may block the flame. Under constant exposure to a hot flame, a thermocouple wears down over time. Even a slight residue can make the thermocouple malfunction.
What if my thermocouple is too long?
Thermocouple cannot have kinks, but copper can be rolled if thermocouple is too long. Thermocouple is finger-tight plus 1/4 turn. Overtigntening thermocouple will short electrical signal to gas control valve. With the mechanical gas control valve thermostats, the pilot flame heats the end of a thermocouple.
What sizes do thermocouples come in?

Can thermocouple wire be spliced?
YES. Temperature probes must be extended with thermocouple wire.
What is a thermocouple?
Simply put, the thermocouple or thermopile as they are sometimes called is a temperature sensor. For safety reasons, the gas valve will not allow gas to go to the manifold unless there is a flame at the pilot to ignite the gas.
What is universal thermocouple?
Most 'Universal' thermocouples include adapter kits along with the thermocouple. This is the best choice in most situation. The package will contain a few different fittings that can adapt to either left hand or right hand thread. Usually, thay also include a couple of different retaining clips for the sensor end of the device.
What does it mean when a thermocouple is hot?
A thermocouple uses two types of metal to create an electrical current that the gas valve can sense. If the electrical current is transmitted, it means that the end of the thermocouple is hot and there is a flame.
Do water heater thermocouples release gas?
From an operational perspective the thermocouples for a water heater are all pretty much the same. However, there are two variables, the length and the fittings used to install them, see below. A failing thermocouple will not send the correct electrical impulse and the gas valve will not release any gas.
Can you use a thermocouple on a left hand?
You need to make sure which thread pattern you have before you order the new thermocouple. Don't plan on trying to make one work that is the wrong thread. They make and adapters that will allow you to use a standard thermocouple on either a left hand or right hand fitting.
