One key component of your home’s heating and cooling system is its thermostat. Unfortunately, just like any other component of your system, your thermostat can occasionally experience malfunctions. Below, we’ll discuss some common troubleshooting tactics you can utilize to help get your thermostat back up and running quickly.
Common Thermostat Problems
Here are some common problems and simple fixes you can safely try.
Unresponsive Screen
One of the most frustrating issues you may experience with your thermostat is that your screen is unresponsive. One of the first things to check is the child lock. While a child lock can be great for preventing others from changing your thermostat settings, it can be a real pain when you forget that you put it on.
If the child lock isn’t engaged and you have a smart thermostat, the issue likely lies with your Wi-Fi connection or the software for your thermostat. Try resetting your thermostat and your Wi-Fi router to see if that solves the problem. If that doesn’t work, try upgrading your smart thermostat’s firmware via your phone app, then reconnect it to your home’s Wi-Fi network.
Blank Screen
One sign that your thermostat is not working is that its screen is completely blank. When your screen is blank, it means your thermostat isn’t getting power. If you have a thermostat that requires batteries, you may have dead batteries. Try replacing them and seeing if that restores power to your thermostat. If that doesn’t work, check the circuit breaker to see if it tripped.
In some cases, you may be able to reset the circuit breaker and restore power to your thermostat. If the thermostat isn’t tripped, it’s likely that there’s an issue with the wiring going to it, or the thermostat itself may need to be replaced. It’s best to schedule a repair appointment for further assistance with this particular matter.
Incorrect Temperature Reading
One particularly perplexing issue you may encounter with your thermostat is that it displays a higher-than-expected temperature. This can happen when your thermostat is placed in a bad location that allows heat-generating appliances or direct sunlight to affect its reading. Take a moment to inspect your thermostat to see if it’s receiving heat from a source that could be inflating its temperature reading beyond the actual ambient temperature.
If there is an unmovable heat source, it’s best to relocate your thermostat to a new location free from any outside influences. If nothing unusual appears to be affecting your thermostat’s temperature, it may be that your thermostat requires a professional recalibration.
Short Cycling
HVAC thermostat issues that may seem more like a system problem occur when your unit short cycles. This happens when the unit is constantly turning on and off. While short cycling can definitely signal an internal HVAC system issue, the problem may lie with your thermostat. Faulty wiring or outdated software can cause your thermostat to tell your HVAC system to constantly turn on and off. Try updating the software to see if that resolves the issue.
Miscommunication With the HVAC System
One sign that you need thermostat troubleshooting is that your thermostat seems to be miscommunicating with your HVAC system. This could cause your system to switch between heating and cooling modes, operate at the wrong temperature, exhibit a lagged response when you make thermostat adjustments, and more.
These problems could point to a software issue, a wiring problem, or an incompatible thermostat. As a diligent homeowner, you can try updating your smart thermostat’s software to see if that solves the miscommunication problem.
When to Call an HVAC Technician
If basic troubleshooting tips, such as replacing batteries, resetting circuit breakers, and updating your smart thermostat’s software, do not resolve your thermostat issue, you’ll want to seek professional assistance. It’s never a good idea to run a thermostat that isn’t operating correctly, as doing so can lead to higher energy bills and internal damage to your HVAC system.
