Hot Water Heater Pilot Light Keeps Going Off

It s the element that detects whether the pilot light is lit by generating an electrical current based.

Hot water heater pilot light keeps going off. 5 improper air flow or a strong draft blows the pilot out. This can happen on excessively windy days or nights. This device detects whether your pilot light is on by generating a heat powered electrical current. This device is designed to pick up an electrical signal from the pilot light s heat to determine whether or not the pilot is on.

As a result the gas supply will be cut off and the pilot light will go out. If you can light your pilot light but the water heater pilot keeps going out there are many possible causes. A faulty thermocouple can cause problems with your water heater not staying lit. In most cases it is advisable to change the burner entirely but first you can conduct some preliminary checks.

There s no hot water in the house. No hot water on a cold monday morning. Again you ll have to do some cleaning. If your gas water heater keeps shutting off the thermocouple could be dirty bent or damaged.

Turn on your hot water tap and wait for about 4 5 minutes for the burner to ignite.

A leak in the output duct of the furnace could cause air to blow into the area. Just remember to turn off the gas before you start. After about 30 seconds heat from the ignited pilot light flame activates a simple electrical switch called a thermocouple which ensures that the gas supply to the pilot stays open and your water heater keeps functioning. The thermocouple is usually easily visible next to the pilot light.

If the pilot doesn t relight if it goes out right after lighting or if the pilot light keeps going out by far the most common cause is a bad thermocouple. Therefore a dirty thermocouple might be the reason why your water pilot keeps going out. If your pilot light re lights easily after going out overnight it s possible it was blown out by a draft.
