Why Does Your Boiler Keep Turning Off in Needham, IN?

You rely on your boiler system for hot water, so when the boiler keeps turning off, it’s a major annoyance. Everyday tasks like showering, washing dishes, and doing laundry become a frustrating headache.

Why does your boiler keep quitting, and what can you do to fix it? Learn about some potential causes of a faulty boiler below, then call us for boiler repair in Needham, IN.

Top Reasons Why Your Boiler Keeps Turning Off in Needham, IN

In some cases, it’s normal for boilers to turn off. Combi boilers feature a pre-heat function that warms the water and holds it in a tank. Once the water gets hot, the boiler will turn off. It only turns back on again to warm up more water.

If your water never gets hot, your boiler likely has a problem that requires attention. Here are some of the most common reasons why your boiler keeps turning off.

A Faulty Thermostat

Just like your HVAC system, your boiler has a thermostat that tells it when to turn on and off. If the thermostat is faulty, the boiler won’t be able to detect the water temperature, which may cause it to shut off prematurely. In some cases, the boiler might turn off to prevent damage from overheating.

Calibrating the thermostat may resolve the problem. If it doesn’t, you’ll have to replace the thermostat with a new one.

Low Water Pressure

Your boiler is a closed system designed to maintain proper water pressure. Over time, though, the water pressure can drop. When it falls too much, the boiler will turn off. You might see an error code on the boiler as well.

Your boiler should have a label on it that indicates the ideal water pressure. Try changing the pressure to the proper level (this may involve opening a control panel somewhere on the unit). If the problem persists, there may be a leak somewhere in the system.

Short Cycling

Short cycling may be another reason why your boiler keeps turning off. Short cycling happens when the boiler repeatedly turns off and on again. Your boiler might run for a few minutes, turn off, and then resume operation.

Short cycling usually indicates that the boiler isn’t the correct size for your Needham, IN, home. If it’s too big, it’ll produce more power than necessary; if it’s too small, it will need to work harder to heat your home’s water, which can cause it to overheat and shut down.

A Blocked Condensate Pipe

Your boiler’s condensate pipe is responsible for routing wastewater out of your home. If the pipe becomes frozen or blocked by debris, it can cause airlocks in the system, and wastewater will back up into the boiler. When the system detects this, it will shut down to prevent further damage.

If your condensate pipe is frozen or blocked, you might hear a gurgling noise coming from the boiler. The system will also display an error code. To fix a frozen pipe, thaw it out with a heat source such as a hair dryer. If the pipe is blocked, you’ll have to call a plumber.

Gas Supply Interruption

If your boiler keeps turning off, there may be nothing wrong with the unit itself. Rather, you may simply be out of gas. Your boiler needs gas to run; without it, it’ll shut down.

Check your gas tank to ensure there’s enough fuel left to power the boiler. Some homes have prepaid meters that control the gas supply. If you’ve used up your credits, the gas supply will shut off. Simply buy more credits, and you’re back in business.

The Boiler Is Old and Needs Replacement

If none of the above troubleshooting steps have helped and your boiler is still turning off, it may be time to replace the unit. Boilers last for about 15 years on average. Around that time, they can start to develop problems that cost a lot of money to fix.

Although a new boiler isn’t cheap, you’ll no longer have to worry about the unit shutting off at inconvenient times. Plus, newer boilers are much more efficient than older models.
