If you have a gas boiler that is used to heat your home, you may have noticed that the pilot light keeps going out. This can be a frustrating problem, as it can cause your boiler to stop working, or even worse, it can be a safety hazard. Fortunately, there are a few things that you can do to try and fix the issue. In this article, we will discuss what to do if your gas boiler pilot light keeps going out.

First, it is important to understand why the pilot light is going out. In most cases, it is caused by a lack of airflow. This can be caused by a dirty filter, a blocked vent, or a faulty thermocouple. If the pilot light is going out due to a lack of airflow, you should try to clean the filter, unblock the vent, or replace the thermocouple.

If the pilot light is still going out after you have cleaned the filter and unblocked the vent, then it is likely that the thermocouple is faulty. The thermocouple is a device that senses the temperature of the pilot light and turns the gas off if it gets too hot. To replace the thermocouple, you will need to turn off the gas at the mains and then unscrew the thermocouple from the gas valve. Once the old thermocouple is removed, you can then fit the new one and turn the gas back on.

If the pilot light is still going out after you have replaced the thermocouple, then it is likely that there is a build-up of soot in the pilot light. This can be caused by a dirty burner or a blocked flue. To clean the burner, you should use a vacuum cleaner and a brush to remove any soot or debris. If the flue is blocked, then you should check the manufacturer's instructions on how to clean it. Once the burner and flue have been cleaned, you should then check that the pilot light is burning correctly.

If the pilot light is still going out, then it is likely that there is a problem with the gas supply. You should check that the gas supply is turned on and that there is no blockage in the pipe. If the gas supply is working correctly, then you should contact a qualified gas engineer to check the boiler. They will be able to diagnose the problem and advise you on the best course of action.

In conclusion, if your gas boiler pilot light keeps going out, then there are a few things that you can do to try and fix the issue. You should first check that the filter is clean and that the vent is unblocked. You should then check the thermocouple and replace it if necessary. If the pilot light is still going out, then you should check the burner and flue for any soot build-up. Finally, you should check the gas supply and contact a qualified gas engineer if necessary.
