It’s inevitably the coldest day in Cincinnati when you go to turn on your boiler, and nothing happens. Not only are you left without the heat you need, but some sudden boiler issues can put your home and safety at risk. To determine how to handle these problems, the team at National Heating and Air Conditioning is here to give you expert guidance. Read on to hear why your boiler needs prompt repairs, along with the most common causes of boiler failure for Blue Ash homeowners.

Why You Shouldn’t Delay Repair When Your Boiler Won’t Turn On
Delaying repairs is never a good idea, as issues with your system can lead to safety and comfort risks. Systems that shut down due to incomplete combustion can put you at risk for carbon monoxide exposure without any obvious warning signs. Another major concern in the winter cold is frozen pipes. Homes without proper heat are more likely to experience a sudden pipe burst that can cause serious water damage and mold growth, leading to unsafe conditions for you and your family members.
Common Causes of Boiler Failure
Homeowners may be able to diagnose some boiler issues on their own. Read on to see how to identify the five most common causes for boiler failure.
Improper Settings/Not Powered On
If your boiler isn’t turning on, it could be an issue with the power or settings. Check to ensure that your breaker hasn’t tripped. Then, confirm that your thermostat is set to “heat” with a temperature higher than the current indoor temperature. If your thermostat is blank, blinking, or not responding, call a technician for thermostat repair.
Water Pressure Issues
If your boiler’s pressure is too low or too high, it may be unable to operate safely. Locate the pressure gauge and look for a number between 1-2.5. If the number is lower or higher, the system will shut off to avoid further damage. Homeowners should schedule repairs promptly, as it could be due to a leak.
Safety Lockout
Boiler systems are designed with a safety lockout in place to automatically turn off the system to prevent unsafe operation. Often, you will see error codes or an illuminated reset light. While a one-time reset may work, repeated lockouts mean your system has a dangerous issue and should be shut off until repairs can be scheduled.
Electrical Problem
Electrical problems like faulty wiring or failed control boards all interrupt power to your boiler and require repairs from a licensed technician. If your system won’t turn on or you hear clicking or buzzing sounds, call to schedule professional service.
Ignition Issues
When your boiler can’t light the burner due to a faulty igniter or gas supply issues, it can be an emergency. Clicking without ignition or ignition error codes are serious safety concerns and should receive urgent attention. Shut your boiler off and call a professional immediately.
