Don’t let your boiler freeze you out this winter


It's getting chilly outside, and while turning on the heat, you realize something is up with the boiler. The first step when experiencing heating system issues is a boiler reset. For your safety, it is best to proceed with caution. It requires adhering to the manufacturer's instructions or consulting a professional for clarification. That said, here's a general guide for how to reset a boiler.
Common reasons a boiler requires resetting include ignition failures or sensor malfunctions. Resetting a boiler usually doesn't demand specialized tools, but the necessary equipment can vary based on the boiler's type, model, and the particular issue you aim to resolve. The one item you must have is your boiler’s user manual—consider it the paramount tool.
Your boiler’s manual details functionalities, safety protocols, and step-by-step troubleshooting guidance. If you find the manual confusing or are uncomfortable performing the reset steps, consult a local boiler repair specialist.
Most boilers have a reset button or switch. It's usually red and on the front of the boiler or the control panel. You may need to refer to the user manual to find the exact location. Press the reset button for several seconds. Afterward, the boiler should reset. If you have a boiler app or a display screen on your boiler, you should get a message if the reset was successful or not.

If the boiler still shows an error code, cut off the power supply at its circuit breaker or gas line and wait up to 10 minutes.
Grab your flashlight if your basement or utility room is a little dark. For an electric boiler, go to your electrical panel and turn off the appropriate circuit breaker. It should be labeled. If not, you must locate the correct one by switching off each circuit breaker until you find the right one.
To turn off the gas, look for a gas valve that should be nearby. The valve might be red and labeled. When in doubt, talk to a boiler specialist.
Afterward, you can restore the power and observe whether the error code on the boiler’s digital display or your app vanishes.
After resetting the boiler, monitor it to see if it starts properly and runs without issues. Pay attention to error codes or warning lights on the boiler's digital display or app. If there are any problems, note the error codes or messages for reference.

If the boiler doesn't start or continues to display error codes or issues, consult your user manual for troubleshooting tips. Different boilers may have specific procedures for diagnosing and resolving problems based on the error codes.
What if the boiler is not still working? If it runs on oil, you might be out. Even modestly sized homes need to fuel up once a year. If you refueled recently and you’re still having issues, call a local boiler specialist.
If you can't reset the boiler or if it continues to malfunction, it's best to contact a qualified technician to diagnose and repair the issue. Attempting to fix complex boiler problems without the necessary expertise can be dangerous and may void your warranty.
The expense of fixing your boiler falls between $200 and $600 on average, although it could reach as high as $1,700 depending on your boiler's specific issue. When you weigh this against the national average cost to replace a boiler—that’s $5,900—it becomes apparent that maintaining your current one might offer a more budget-friendly solution. However, it's worth considering a replacement if your boiler has surpassed the 15-year mark.
