Thermocouples are designed to detect a pilot light's loss of heat and close the gas valve to prevent a gas leak. Replacing a thermocouple is a relatively easy fix that can take less than two hours.
What happens when your thermocouple goes bad?
The thermocouple can do this because, in its probe, it contains two different metals, and a voltage is generated when one of them is heated. This is the result of a phenomenon known as the Seebeck Effect. Nothing lasts forever, and when the thermocouple wears out, the pilot won't stay lit and your appliance won't work.
How much does it cost to replace a thermocouple on gas hot water heater?
The cost to replace the thermocouple on a water heater is $100 to $325. The thermocouple detects whether the pilot light is lit and signals the gas control valve to turn on the gas flow. Thermocouple replacement is the most common repair needed for gas tank water heaters.Jun 15, 2021

How much does it cost to replace a thermocouple on a furnace?
Cost to Replace a Thermocouple on a Furnace Replacing a thermocouple costs $150 to $250, mostly due to labor time. On older models without an ignitor, it checks to make sure your pilot light is lit. If it's not, it'll shut the gas off.

How much does a plumber charge to replace a thermocouple?
Calling a professional plumber to install a new thermocouple should only be up to $150. If you do the work yourself, you will only pay the price of the part which is about $20. The thermocouple is responsible for sensing that the pilot light is lit and triggering the gas control valve to continue providing gas.
