Why does my gas boiler not ignite?
Some boilers won’t ignite if the gas or water pressure is too low. Low gas pressure could be a problem with supply in the area and you may need to call out the supplier to check. Alternatively, it may be that the water pressure is too low in a sealed system boiler.

There are air and gas flow sensors that require cleaning, as does the orifice through which the gas flows to the burner unit pilot light. The control valve contains a temperature probe…
Why is my gas fireplace pilot not working?
Like anything else in this work, the thermocouple can wear down over time and stop working. When the thermocouple does wear down and finally stop working, the pilot can’t remain lit and your fireplace won’t work as it should.
