WebThe key part of the thermocouple is a probe that sits close to your oven's pilot flame. Another junction of the thermocouple rests in a cool part of your appliance where the temperature will remain consistently low no matter what. When the pilot flame is burning, it heats the probe and causes a current to flow through the thermocouple's circuit. WebA thermocouple is a sensor for measuring temperature. This sensor consists of two dissimilar metal wires, joined at one end, and connected to a thermocouple thermometer …

WebDec 15, 2024 · The job of the thermocouple is to keep the pilot lit. It does this by sending a tiny electric current to a sensor on the gas valve signaling the valve to stay open. 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. WebThermocouples 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. This guide reviews how to replace a thermocouple to ensure gas appliances stay in good working order, as well as how to relight a pilot light. fitz hugh curtis icd 10
