Having boiler problems can be a big inconvenience for your family, as well as a big drain on your bank account. If you wake up one morning this winter and discover that your home isn’t as warm as it should be, consider these troubleshooting tips before you call for expert help:
- If the boiler will not turn on, check the thermostat. Be sure it is set to the “heat” position and the temperature setting is high enough to make the boiler come on. Don’t forget to check the batteries. Dead thermostat batteries are the cause of more HVAC service calls than you might expect. Older thermostats can fail to control system temperatures correctly. If you have an older manual thermostat, consider replacing it with a new programmable model for reliability and energy savings.
- After you check the thermostat, make sure the boiler is getting electric power and heating fuel. If you find tripped circuit breakers or blown fuses, try re-setting or replacing them. If the circuit fails again as soon as you turn the boiler back on, you probably have a pump that has burned out or another electrical problem. Make sure the natural gas or oil supply valve is open and that you have oil in the tank if you’re using heating oil. If your system has a standing pilot light that’s gone out, try to re-light it. If it won’t stay lit, you might need a new thermocouple.
- Maybe the boiler seems to be working correctly, but the radiators are making a lot of noise or they’re not delivering heat. If this is the case, you might have air trapped in the system. Look for bleeder valves on the radiators and carefully bleed air from them.
- Know your limitations. Don’t attempt to do any troubleshooting or repairs unless you’re certain that you can do the work safely and effectively. If these simple troubleshooting steps don’t solve your boiler problems, or if you are not sure you know what you are doing, call for expert help.
