What to Do If Your Home Thermostat Malfunctions

by lizzieweakley

A home that’s too hot in the summer and too cool in the winter can be an uncomfortable nightmare. While many people assume the HVAC system is always to blame for heating and cooling issues, this isn’t always the case. If you can’t keep your home at the temperature you desire, it may be time to check your thermostat. Here’s what you should do if your home thermostat malfunctions.


Check the Power Source

If you notice the screen on your thermostat won’t light up, you should check the power supply. If your thermostat’s batteries are dead, this will prevent the display from lighting up and showing the temperature. This is an easy fix, so be sure to try it before assuming your entire system has gone haywire.


Examine the Wiring

If your system won’t turn on, this can be a sign of faulty or damaged thermostat wiring. Wires that send signals from the thermostat to your system can’t function properly if they are broken. When wires are out of order, there is no communication between the thermostat and your system. This may be why your system isn’t kicking on when you adjust the temperature on your thermostat.


Check Calibration and Programming

If your HVAC system won’t turn off, this can cause your energy bill to skyrocket. When your thermostat is set to “off,” your HVAC system shouldn’t be running. If you aren’t able to shut off your system with the thermostat, it may need to be calibrated. This problem can also be caused by wiring issues, so you may need a professional to come out and take a closer look.


Call an HVAC Specialist

If you aren’t sure what is causing your thermostat to malfunction, you can rely on a specialist like Keefe HVAC to diagnose and repair your thermostat. Thermostats and HVAC systems are complex, and the problem isn’t always obvious. If you need help fixing your thermostat, it’s best to call someone as soon as possible so you can make your home comfortable again.


If your home is uncomfortable, you don’t have to suffer another day. Follow these tips to diagnose your thermostat issue so you can have it fixed as soon as possible. Whether your thermostat needs a quick battery change or professional repairs, you should fix it as soon as you can to avoid high energy bills, damage to your HVAC system, and uncomfortable indoor temperatures.
