It's a fricking copper wire. It doesn't have any moving parts.

There's nothing worse than thermo divorce. Hope there weren't any thermo kids involved.

Making shitty water heater parts that break and malfunction is a great way to sell a lot of water heater parts.

Not sure but i had one go bad on my dryer and gas fireplace within a month of one another. Cheap and easy fix.

It's actually probably Cooper and Constantine. If it's not it's at least two disimiliar metal wires connected at one end. It also probably not the point of failure but more likely the electronic device that actually reads the mv produced by the metals that's failed. That assumes of course that it's even a t/c to begin with. Could be a bulb or thermistor, both of which as more susceptible to failure than a t/c.

Gets into the wrong crowd?

Show me your water heater's fittings, I'll show you yourself.

Yep. Two copper (or similar metals) wouldn't be a thermocouple. Two factors cause thermocouples to fail in these instances - thickness of the tubing/insulated cable or size of the metal wires. No doubt these OEMs use very thin-walled tubing and very small gauge wire (24awg). Over time, these can fail due to being exposed to elevated temperatures for extended lengths.

Good thing is that they are a cheap and easy fix.

And it's more than likely a resistor (RTD)
