Your boiler is not switching on? Here’s more information about this boiler problem.
While your boiler is made to last for a very long time, it is bound to encounter mechanical issues along the way. A boiler breakdown does not mean the end of the world though. Many boiler problems can be easily fixed. If your boiler is not switching on, it is most likely caused by one of these things below.
Boiler Is Not Switching On
Here are the most likely reasons why your boiler is not switching on:
- Thermostat. The thermostat must be set to the heat position. The set point must also be below the temperature in the room. The thermostat settings can accidentally change. Set it a few degrees below the room temperature and wait for the system to start. If the heating system does not work, check the next item on our list.
- Electrical Problem. Most new boiler models use an electric ignition, a safety blower that is used to vent combustible gas, and circulation pumps. All of these components are powered by electricity. Check to make sure that the circuit breakers are not tripped. If they are, you can reset them. Also make sure that the service safety switch is on.
- Gas Supply. If the first two items are working okay, and your boiler is still not switching on, check your boiler’s gas supply and make sure there is sufficient gas going into the boiler. The shut off valve must be open.
- Faulty Component. Finally, if you boiler is not switching on still, the likely cause is a faulty component. Boiler parts become dirty and wear out over time. Air and gas flow sensors need cleaning, as well as the orifice through which the gas flows to the burner unit pilot light. The temperature probe in the control valve will shut the system off if it malfunctions. The thermocouple stops the flow of gas if the pilot light is off. Other parts of the boiler such as the electronic ignition system and condensate pump may also be malfunctioning.
While you can work on the thermostat and circuit breakers yourself, working on supply lines and replacing boiler components must only be done by a professional engineer. Having someone inexperienced do the work will not save you money; it may only increase the risk of gas leak and other accidents.
