Water Heater Pilot Light Keeps Going Out: The 4 Main Causes

Check the thermocouple:

If the water heater pilot light keeps going out when windy, then the thermocouple might be responsible for that. It is the flame sensor and maintaining the flame is its responsibility. Due to excessive use, the thermocouple can be dirty, broken, or misaligned. When it senses the absence of flame it immediately shuts off the gas supply in the gas water heater. It wouldn’t be wrong to call it the safety device of the heater. Shutting off the gas might be annoying but the whole system is designed to ensure your safety. Because not everyone has outdoor space to install the heaters. If the supply isn’t shut off, then it can spread and cause serious damage to the health of people.

A faulty thermocouple doesn’t see the flame and cut off the gas supply. Before you blame the thermocouple, take a look at it if it is dirty because it can affect its working efficiency. You can simply clean the thermocouple and your flame will turn on again. The pipe of the thermocouple is of copper colour, so make sure it is cleaned properly before you try to turn it on. It is also a possibility that you have to replace the thermocouple if it’s completely broken. Just buy a device of a similar model and replace it. Remember to shut off the gas supply before attempting the replacement.

Watch out for downdraft:

The second big reason behind your pilot light on water heater keeps going out is the downdraft. The downdraft is the upward or the downward air current. This issue is directly related to the ventilation system and if you have verified that your pilot is clean, then it is time you test your ventilation system. Checking the functionality of the ventilation is quite easy, you just have to place your hand on the ventilation pipe and see if you feel cool air running toward you. Be careful, because the exhaust pipe is located nearby so don’t burn your hand mistakenly. If you feel a cold air current, then it means your ventilation system is working properly. If you feel some slow and warm airflow it means, there’s something wrong with the ventilation system. It is probably throwing the warm air into the chamber due to some blockage. Now that you have identified the issue clear the blockage and your heater will return back to normal. This particular scenario was in the case when ventilation is installed separately from the chimney. If it is combined, then you might have to climb up and deal with the blockage and if you don’t feel comfortable with the idea, it would be better to hire a professional.

Malfunctioning of gas release or heating element

A water heater has numerous small parts that can cause issues without your knowledge. First of all, it is important to verify if there’s an appropriate gas supply available for the hot water heater pilot to turn on. The water heater pilot turns on after receiving a spark from the heating element. If the pilot doesn’t turn on, then check out the heating element if it is performing its task. The spark can be seen clearly when you push the button and if you don’t see the spark, then check if the electric supply is connected. If that doesn’t work either, then it would be good if you consult a technician for that.

Another reason why your pilot turns off is probably the gas supply if the gas water heater doesn’t have a regular supply of gas or has a leak in the pipe or some push-button is broken, then there’s a chance that you won’t be able to light a water heater pilot. In this case, it is important to track down the supply issue and fix it. However, fixing such an issue might not be an easy task and you might have to consider hiring an expert for the task.
