Check the Power Supply
Sometimes, a simple fix can resolve a seemingly complex problem. At the first sign of your thermostat not working, check its power supply to make sure it’s connected. To do this, turn off the power to your HVAC system from within the breaker box and reset its terminal.
If your thermostat runs on batteries, try swapping them out since low battery power is a common cause of malfunctions. To check your thermostat’s batteries, you’ll first need to remove the thermostat from the wall. Then, use a screwdriver to remove the battery cover and replace the old batteries with fresh ones. Reattach the cover once the new batteries are properly aligned and test the thermostat’s operation.
Verify the Settings
Does your thermostat have a mind of its own? You may need to check its settings. Start by checking its programming — sometimes, the issue can be traced back to an improperly set temperature range or an incorrect mode. Referring to your thermostat’s user manual can help you navigate its control settings.
If your thermostat is set incorrectly, it may reach a limited temperature range or fail to cool or heat your home effectively. Sometimes, the settings might be optimized for a different HVAC system. For example, a thermostat programmed for a furnace may not work efficiently with a heat pump system.
To avoid this issue, check that the thermostat settings are compatible with your HVAC system and set to a temperature that comfortably covers your entire home.
Clean the Thermostat
Is your thermostat still not fixed? It may need a thorough cleaning.
Dust and debris trapped inside the thermostat can affect its performance and disrupt your home’s HVAC system. It’s important to regularly clean your thermostat to avoid preventable issues from dirt or grime.
To clean your thermostat, we recommend using a soft brush or compressed air to remove debris from the interior. For the exterior, a gentle wipe-down with a damp cloth will do.
If you notice weak airflow, cool drafts, or inconsistent heat, the issue may lie with your ductwork, not the thermostat. In that case, it’s best to call an HVAC professional.
