If the thermocouple thinks it's safe, then it allows the main gas valve in the pilot assembly to open up and stay open. If you are using this, just make sure that you dont leave any residue behind. In addition, you can check whether the connector is loose or not. Asking for help, clarification, or responding to other answers. Right-click on the page and select "Inspect" or press "Ctrl+Shift+I" on Windows (or "Command+Shift+I" on Mac) to open the browser's developer tools. When it stops working, the furnaces pilot light also turns off. This loss of accuracy is often caused by electromagnetic interference, (EMI). How can I trust a K-type thermocouple purchased from a no-name company? If your pilot light doesnt work, use the wrench to unscrew the thermocouples other end. The thermocouple is an electrical wire that measures temperature by the amount of voltage generated between the two ends. Connect the new thermocouple to the pilot burner assembly bracket, tightening the nut (s) until it's just snug. Here are some tips and tricks for using an action camera flashlight to get the best results: 1. Copyright 2022 webinvogue.com. 0000001396 00000 n In IEC color-coded thermocouples the negative wire is always white. Electrical noise can cause measurement errors especially when using grounded thermocouples.
