Why Won’t Your Boiler Shut Off in McLean, VA?

December 26, 2022

McLean, VA has many historic homes and neighborhoods that still use boilers. While you need that boiler on cold days, even a new one can run all day and night and refuse to shut off. Find out some of the reasons why it won’t turn itself off.

Stuck Valve

Your boiler has a valve that opens and closes to let gas through and shut off the flow. When it’s open, your boiler uses the gas to heat the water. If the valve becomes stuck in the on position, it will run constantly.

Thermostat Problems

The thermostat and boiler work together to keep your home at a comfortable temperature. Any issues with your thermostat can send the wrong signal to the boiler or send no signal at all. You may just need to replace the battery, but you may need another type of heating repair.

Malfunctioning Programmer

Your HVAC system has a programmer that receives signals from the thermostat, which allows it to control how the boiler runs. If there is a problem with the wiring within the programmer or between the programmer and the thermostat, the boiler may continue running and not shut off.

Loose Wiring

Boilers have many different wires that connect and control the various components. Damage to any wiring or loose wiring can make the boiler run all the time, especially any damage near the low-temperature switch; this switch keeps the boiler running if it senses that the water isn’t heating. Repairing wires often requires taking the boiler apart, which is a job best left to the pros.
