Can I use a universal thermocouple?

Universal Thermocouples. Universal thermocouples, as the name implies work on most water heaters. They are available online and in home supply stores for a reasonable cost.

Can I replace my own thermocouple?

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. Then unfasten the three nuts that hold the thermocouple and the two gas tubes to the valve.

How do you replace a universal thermocouple?

How to Replace a Thermocouple

Shut Off Gas and Power. Before getting started, turn off the electrical power to the furnace by rotating the toggle switch mounted on the furnace to the OFF position.
Open Access Cover.
Remove Old Thermocouple.
Install New Thermocouple.
Connect the Gas.
Turn On Gas and Power.

How does a universal thermocouple work?

A universal thermocouple is a safety device that can detect whether the pilot light that ignites the gas is lit or not. This rod connects to your furnace’s gas valve. When the pilot’s light flame is lit, the end of the metal rod gets heated and it sends a voltage through the thermocouple that keeps the gas line open.

What does a bad thermocouple look like?

Before jumping to the conclusion that the thermocouple is at fault, look at the pilot flame. If it appears small and has an orange-yellow tinge, it may be too weak to heat the thermocouple. The likely problem, again, is an obstruction in the pilot tube.

Can a Honeywell thermocouple be used in a state water heater?

Yes, you can use the Honeywell 30mV t-couple with the State if/when the threads in the gas control valve seat fit. Lastly, note that some State water heaters have a high-temperature shunt soldered in-line with the thermocouple.

Do you need a socket for a thermocouple?

If the electronic measuring instrument (e.g. temperature transmitter) is located near enough for the thermocouple’s wires to reach the connection terminals, no plug or socket is needed at all in the circuit.

What kind of tip do you use for a thermocouples?

Sheathed tips are typical for industrial applications, available in either grounded or ungrounded forms:

Can a thermocouple be connected to a solid wire?

While this may form a usable connection at first, compression-style terminals are simply unable to maintain adequate compression when applied to solid wire of any type, thermocouple wire included. Over time, solid wires will loosen inside compression terminals leading to circuit problems.
