If your house feels cold even though the heating is on, the thermostat is the first place to check. It’s the brain that tells the boiler or furnace when to fire up, so a small glitch can make the whole system think it’s already warm. The good news? Most thermostat issues are easy to spot and fix without calling a technician.
Look out for these red flags:
When you see any of these, start with the basics before moving to more involved steps.
1. Check the power source. Battery‑operated thermostats need fresh cells. For wired units, make sure the breaker hasn’t tripped and that the wiring is snug.
2. Verify the settings. Make sure the mode (heat, cool, auto) matches what you want, and that the fan is set to “auto” instead of “on” unless you need constant airflow.
3. Clean around the unit. Dust on the sensor or inside the casing can cause false readings. Turn the thermostat off, remove the cover, and gently vacuum the interior.
4. Reset the thermostat. Many models have a reset button or can be reset by turning the power off for a minute. This clears minor glitches.
5. Calibrate the temperature. Use a reliable room thermometer placed nearby. If the thermostat reading differs by more than 2°F (1°C), you may need to recalibrate according to the manufacturer’s guide.
If these steps don’t solve the problem, the issue might be deeper – a faulty sensor, worn-out relay, or wiring problem. At that point, it’s safest to call a professional like Rugby Appliance Repair Services. Our technicians can test the thermostat’s internal components, replace a bad unit, or repair wiring safely.
Remember, a thermostat that’s out of sync can waste energy and raise your bills. Simple maintenance – changing batteries, cleaning dust, and checking settings – keeps it running smoothly all year long.
