## AC Not Responding to Thermostat? Here’s What You Can Do
If you’ve determined that your AC is no longer responding to your thermostat, it’s likely because of a faulty circuit board, a disconnected wiring harness, or some kind of power failure. In this article, we explore what could be causing your AC system to malfunction, and how to diagnose and fix it.
### Causes of AC Non-Response
The primary reason why an AC might stop responding to a thermostat is an issue related to the power source. Additionally, there could be a fault in the wiring or with the circuit board.
* Faulty Power Source
If the power source to your AC unit or thermostat is compromised, the device may not respond to commands. This can be due to a power surge, an overloaded circuit, or a malfunctioning power or circuit breaker. In such situations, you need to identify the issue and fix it to ensure your AC runs smoothly.
* Wiring Connection Issues
The wiring harness between the AC unit and the thermostat can become disconnected, which can cause communication failures. This often occurs if the wiring has sustained physical damage in some way, such as due to a rodent infestation or a loose connection. In this case, you need to inspect the wiring to locate the disconnected link and repair it.
* Malfunctioning Circuit Board
If the circuit board in either the AC unit or the thermostat fails, either or both devices may not respond as expected. This could be due to a damaged or faulty part, or simple circuit malfunction. To restore communication, you need to repair or replace the circuit board, depending on the severity of the problem.
### Diagnosing a Malfunctioning AC Unit
If your AC unit is no longer responding to the thermostat, you need to troubleshoot the problem and diagnose the root cause. Here’s a step-by-step guide to help you do this.
* **Step 1:** Check to see if the power source is functioning correctly. If there is no power at the unit, examine the source to determine the cause of the power downtime.
* **Step 2:** If the power source is functioning properly, inspect the wiring between the AC unit and thermostat. Make sure all of the connections are fully installed and securely connected.
* **Step 3:** If the wiring is properly connected, then the issue is likely a faulty circuit board. Take the unit apart to locate the circuit board and inspect it for malfunctions.
### Fixing Malfunctioning AC Units
Once you have identified the cause of the malfunction, you can take steps to fix the issue.
* **Fixing Power Source Issues:** If the power source is not functioning correctly, you need to identify and repair the issue. This could involve replacing a faulty power cord or resetting a circuit breaker.
* **Fixing Wiring Connection Issues:** If the wiring between the AC unit and thermostat has become disconnected, you need to locate the faulty connection and repair it. Depending on the type of wiring, you may need to replace it if the damage is too extensive.
* **Fixing a Faulty Circuit Board:** If the circuit board is faulty, you may be able to repair it by replacing individual components. However, if the board is beyond repair, you will need to replace it with a new one.

When an AC unit is not responding to its thermostat, it is important to take preventive action to ensure its functionality. In San Diego, manufacturer and local appliance or HVAC technician recommendations include:

FAQ – AC Not Responding to Thermostat
Q1: What could cause an AC not to respond to the thermostat?
A: Malfunctioning or faulty wiring in the system, a bad thermostat or a frozen evaporator coil due to a blocked filter can all cause an air conditioning system to stop responding to the thermostat.
Q2: How can I check the thermostat for problems?
A: First, ensure your thermostat has fresh batteries installed. Next, check that all the wires are firmly plugged into the thermostat terminals and the wall. If all is well, try resetting the thermostat to factory settings.
Q3: How do I know if I have a frozen evaporator coil?
A: A frozen evaporator coil will cause air to stop flowing out of the vents. This is because a build-up of ice stops the air from passing through. If this occurs, a blocked filter is the likely culprit, and should be checked and replaced if necessary.
Q4: How can I prevent my air conditioning system from failing again?
A: Regular maintenance is the best way to prevent AC failure. Ensure you change the system’s air filter regularly, and have your system serviced annually by a certified technician to keep it running efficiently.
