6 Reasons Why a Water Heater Pilot Light Won't Stay Lit

Nothing is more disappointing knowing that you have to run the water heater but found out that it does not work. If the pilot light of the water heater will not stay lit, there must be a problem. Want to know the reasons why? Read on to learn!

  1. Bent Thermocouple

The thermocouple is composed of small copper wires and rod. It is a safety device connected to the pilot assembly, which is found at the lowest portion of the water heater. The role of the thermocouple is to keep your home safe from fire hazards by turning off the gas if an issue on the heater occurred. But if the thermocouple is bent, it will not function correctly, which can result in fire and other problems.

  1. Dirty/ Clogged Thermocouple

The output of the electric current is affected or restricted when the thermocouple is covered with dirt and debris.  Removing the dirt should not be hard for you especially if you want the best comfort for your home. Before cleaning the thermocouple, make sure it is cool and the gas is turned off.

  1. Impaired Thermocouple

A broken thermocouple might be the reason why the pilot light does not stay lit. To solve this problem, you can either repair or replace it. If you opt for repair, you will need to look for an experienced technician to do it. Testing if the thermocouple is damaged is easy via a multimeter to see if the voltage is coming through.

  1. Dirty Pilot Tube

This part of the water heater can easily accumulate dirt and dust. If neglected, dirt may continue to build up and block the flow of gas. Clean the tube with the help of experts to ensure quality results. Check if the pilot lights up again after cleaning.

  1. Problems With Flex Tube

The flex tube acts as a connector between the gas controller and the system. Any issue on the flex tube will affect the stream of gas to the system that makes it work. See to it that there are no kinks in the tube.

  1. Incorrectly Positioned Thermocouple

Just make sure that the thermocouple is located in the right place. Ask professionals to check if the size of the flame is enough to reach the thermocouple to ensure that the water heater will work properly.

Doing major or even minor repairs on the water heater is not your typical do-it-yourself task. Always ask the experts for help and guidance. Call us at McKenna Heat and Air today.
