Winters in Centennial, Colorado, are usually cold, with temperatures below freezing. Having a functional heating system like a boiler is crucial for wintertime comfort and safety. If you have a boiler not turning on with thermostat signals, you’ll need to know why – and fast.
As the go-to heater repair contractor in Centennial, CO, Southwest Heating & Air Conditioning Repair is well-versed in boiler issues. Below, the team shares several reasons why your heating equipment might be failing to turn on as the thermostat kicks in.
Reasons Boilers in Centennial Homes Won’t Respond to Thermostat Controls
Many people in and around Centennial rely on boilers to heat their homes comfortably. Though the last thing you’d want to deal with in the middle of a blisteringly cold Centennial day is a malfunctioning boiler, these situations happen. Your thermostat should prompt the heating system to turn on according to its settings, so if it doesn’t, these boiler problems could be responsible:
No Power To Boiler
Whenever you have a boiler not turning on with thermostat readings, the first step in resolving the issue is simple: check the boiler’s power source.
Sometimes, Centennial homeowners make thermostat adjustments expecting to turn on their boilers as they do, only to discover that the boiler isn’t connected to electricity. Whether you have a gas or oil boiler, it’ll need electricity to power its electronic ignition system.
This power switch closely resembles a light switch and is typically close to the boiler. Look for the switch and ensure it’s in the “On” position. The thermostat will then be able to talk to the heating system.
Closed Gas Valve
Does your Centennial residence rely on a gas boiler for warmth? Is that boiler not turning on with the thermostat? Check whether the gas valve is open or not.
The gas valve regulates how much gas can enter your boiler. It must be open for enough gas to flow into the equipment to generate heat.
Thermostat Issues
Sometimes, boilers are fully functional but won’t turn on because of a malfunctioning thermostat. If you suspect the thermostat itself is impacting your boiler’s performance, check the device’s power supply first.
Most thermostats are battery-operated. Often, changing the batteries might be enough to restore the thermostat’s functionality. Verify that the thermostat has a good power supply and turn on its heating mode.
If you have a programmable thermostat, punch in the correct time and date, as well.
Tripped Circuit Breaker
If the heating system trips your home’s circuit breaker, you’ll have a boiler not turning on with thermostat changes. The breaker panel shuts off power to appliances and outlets that are pulling too much electricity. It’s a safety measure.
Flip a tripped breaker back into the “On” position. If your boiler keeps tripping the breaker, it’s experiencing another problem. Get help from a Centennial HVAC expert like Southwest Heating & Air Conditioning Repair.
Ignition Failure
Centennial’s gas and oil boilers produce heat with the help of a pilot light, which triggers the combustion process that burns fuel. Without the pilot light, the boiler can’t ignite.
The problem here might just be a dirty or malfunctioning flame sensor, which is an easy fix. Safety switches and sensors prevent boilers from burning fuel if they detect potentially unsafe conditions. Even if your boiler is working safely, it won’t respond to the thermostat trigger if these sensors think there’s a problem due to a filthy flame sensor (or something else).
Still Experiencing a Boiler Malfunction? Equipment Replacement May Be the Answer
Any time your boiler fails to communicate with the thermostat, you should contact an HVAC expert in Centennial. These professionals can inspect and evaluate electrical parts and systems to quickly uncover the cause of the performance disruption and repair it.
They may recommend replacing your heating system with a modern, energy-efficient model if your home needs a more reliable heat source ahead of Centennial’s winter months.
