How to Replace Your AC’s Faulty Thermostat

Steps to Replace Your AC’s Faulty Thermostat. A faulty thermostat on your AC is one of the most common problems homeowners experience. It can cause your air conditioner to run inefficiently and can even lead to complete system failure. Fortunately, replacing it isn’t too difficult, and can be done with a few simple tools. By following these steps, you can replace your AC’s faulty thermostat in no time at all.

Prepare the Space

The first step to replacing your AC’s thermostat is to make sure that the area is clean and free of debris. Make sure to remove any furniture or other items that might get in the way of the job, and dust or vacuum the area if necessary. This will ensure that you can move and work freely, without anything getting in the way.

Turn off the Power

Before you start working, it’s essential to make sure that all the power to the AC is turned off. This can be done by flipping the appropriate breaker in the circuit box. It may be labeled “AC” or simply “Thermostat”. Once it is off, you can start unplugging the thermostat wires from the base unit.

Remove the Faceplate

Once the power to the thermostat is off, the next step to replacing it is to remove the faceplate from the wall. This is usually done by removing the screws that secure it in place and carefully lifting it off the wall. Once the faceplate is off, you can access the wires connecting to the thermostat.

Disconnect the Wires

Once the faceplate is off, you’ll be able to access the wires that are connected to the base of the thermostat. Disconnect them from the base, making sure to keep track of which wire goes where. It is important to remember which wire was connected to which terminal, as each one needs to be connected back in its original place in order for the new thermostat to function properly.

Remove the Old Thermostat

The next step is to remove the old thermostat from the base unit. This is usually done by unscrewing the two mounting screws that hold the thermostat in place and then gently lifting the old thermostat off the base unit. Once the old thermostat has been removed, take note of the wiring that was connected to it.

Install the New Thermostat

Once the old thermostat has been removed, it’s time to install the new one. Carefully remove the new thermostat from its packaging and place it against the wall. Secure it by screwing the two mounting screws back in place. Now attach the wires connected to the old thermostat to the new one, making sure to match them up correctly.

Connect the Wires

Once the thermostat is in place, the next step is to connect the wires to the base unit. Match the wires up with the correct terminal and ensure they are connected firmly and securely before moving on to the next step.

Restore the Power

Once the wires have been connected to the base unit, the next step is to restore the power. This can be done by flipping the appropriate breaker in the circuit box back on. This will cause the thermostat to begin functioning again.

Test the Thermostat

Finally, the last step is to test the thermostat to make sure that it is working properly. Set the thermostat to a temperature different from what it currently is set to and wait a few minutes. If the temperature in the room does not change, then you know that the thermostat is working properly.

Replacing your AC’s thermostat can be a simple process when done correctly. By following these steps and taking the time to ensure that everything is connected properly, you can make sure that your new thermostat is functioning properly and that your AC is running efficiently.
