If your boiler is not turning on, there are several steps you can take to troubleshoot the issue:
Ensure that your boiler is receiving power. Check the circuit breaker and fuse box to make sure there are no tripped breakers or blown fuses. If necessary, reset the breaker or replace the fuse.
Verify that your thermostat is set to the desired temperature and is in the "heat" mode. Sometimes, the thermostat settings may have been accidentally changed.
For older boilers with a pilot light, check if the pilot light is lit. If it is out, you may need to relight it according to the manufacturer's instructions. For newer boilers with electronic ignition systems, ensure that the ignition system is functioning properly.
Check the water pressure gauge on your boiler. If the pressure is too low, your boiler may not operate. Refer to your boiler's manual for the recommended pressure range and instructions on how to add water to the system if needed.
Modern boilers often display error codes when there is a problem. Refer to the boiler's manual to interpret the error code and follow the recommended troubleshooting steps.
If you have tried these steps and your boiler still does not turn on, it is best to contact GSMS.
