    Window Air Conditioner Thermostat Problems (Signs of A Bad AC Thermostat)

    A failed window AC thermostat is easily detectable when using the unit. So, whenever you notice the signs, there is a chance the thermostat might be misbehaving or probably broken down.

    The problems or signs in question include the following:

    1. Window Air Conditioner Not Turning On

    While there are different reasons why a window air conditioner won’t turn on, one of them is a faulty thermostat. If the thermostat is broken or shorted, it will prevent the air conditioner from starting. Remember that the wrong thermostat setting can prevent the AC from turning.

    2. Window Air Conditioner Not Cooling

    A faulty thermostat can also prevent an air conditioner from cooling. Sometimes, however, the AC won’t cool, not because the thermostat is defective but due to the wrong setting.

    For example, setting the thermostat on ‘Heat Mode’ will heat and not cool. But as far as a faulty thermostat goes, check for signs of breakage and poor installation. They could be the reason the window AC won’t cool.

    3. Window Air Conditioner Not Heating

    Just like a faulty or incorrectly set thermostat will result in a non-cooling window AC, it’ll equally result in a non-heating one. For example, the AC won’t heat if the thermostat is on ‘Cool Mode.’

    That, however, doesn’t mean the window AC is faulty. You can tell a faulty AC if you can’t adjust the temperature.

    4. Window Air Conditioner Running Continuously 

    The thermostat typically signals the window AC to turn off once it reaches a specific temperature. That, however, won’t happen if the thermostat is faulty.

    Instead, your air con will continuously run until you power it off and fix the thermostat (or replace it).

    5. Window Air Conditioner Not Reaching a Room Temperature

    The thermostat should operate at a summer temperature of about 25.50C or a winter temperature of 20 – 220C. That, however, won’t be the case if the thermostat is defective. 

    It’ll have difficulty reaching that temperature limit once you preset it. So, the window air-con may blow very cold or hot once the thermostat malfunctions.

    6. Shorter Air Conditioner Cycles

    Lastly, a faulty thermostat could cause your window air conditioner to run shorter cycles. That is odd and leads to costly energy bills, something to avoid.

    7 Window Air Conditioner Thermostat Troubleshooting Steps

    Now that you recognize the signs of a failing thermostat, here are seven steps to get it working:

    Step 1 – Check and Set the Temperature Correctly (Window Air Conditioner Thermostat Adjustment)

    Unless the temperature is set correctly, an air conditioner’s thermostat won’t work. So, this is an important check.

    First, ensure the window AC is in Cool or Max Cool mode. After that, ensure that the setting is as low as possible. 

    Also, turn off Child Lock (CL) if it’s on. Doing that shouldn’t get the thermostat working if the issue was the setting. If it doesn’t, then you should adjust the thermostat using these simple steps:

    • Turn the AC on if it’s off by pressing the ON/OFF switch

    • Wait for the air conditioner to start and display the temperature

    • If it doesn’t, press ‘Mode’ and wait for it to beep and display the temperature

    • Then use the up/down arrows on the front panel or remote control to either lower or raise the temperature

    Step 2 – Clean The Air Conditioner (Especially The Filter And Coils)

    Too much debris, dust, or dirt blocks the filter and coils, causing the thermostat to start misbehaving. It is unable to run normally, resulting in cooling and heating issues. So, you must inspect the unit, especially the filter and coils, for dirty clogging and clean them.

    Also, clean the thermostat, which you can locate beneath the front cover. You can use a paper towel to do it.

    Step 3 – Look for A Tripped Breaker or Burnt Fuse

    If your window air conditioner or the thermostat doesn’t turn on, the problem could be a power failure due to a tripped breaker or burnt fuse. The breaker will likely fall/trip when the AC experiences a current overload.

    The same goes for a burnt fuse. So, check them. If the breaker is tripped/off, reset it. `

    As for the thermal fuse, you’ll need to test it with a continuity tester (multimeter). An absence of meaningful continuity suggests the fuse is bad and requires replacement.

    Step 4 – Change the Remote Controls Batteries

    Sometimes, the cause of the window air conditioner thermostat not working could be the remote control and not the air con. If the remote control doesn’t turn on the AC, the thermostat won’t work.

    So, start by replacing the remote control battery, especially if it has been a while since doing so. And while replacing them, ensure you install the fresh pair correctly according to polarity.

    Step 5 – Identify Any Bad Wiring

    If there’s a problem with the thermostat’s wiring, the thermostat will malfunction. So, it’s worth checking the wires for loose connections, breakages, detachments, and corrosion.

    That means you must locate the thermostat beneath the front panel to inspect it. But if you can’t do it, call an HVAC technician to handle this step and the other remaining two, depending on the problem.

    Step 6 – Inspect The Thermostat Sensor

    The thermostat has a sensor that dictates its running. If the sensor is defective, the thermostat may turn on and off irregularly or fail to switch on/off entirely.

    So, when you notice such signs, inspect the thermostat sensor. Use your manual to locate the thermostat sensor and check for loose connections or bending.

    You can also examine it with a multitester/multimeter, and if it doesn’t show continuity, replace it, as that proves it’s defective.

    Step 7 – Check for Poor Installation

    Lastly, if you still can’t troubleshoot the window AC thermostat up to this point, consider checking its installation. If the installation is poor, the thermostat won’t work.

    In particular, check to see if the thermostat is dislodged. If it is, uninstall it, then re-install it correctly.
