KEY TAKEAWAYS:
- Unlocking your air conditioner allows users to change the thermostat settings right from the control panel.
- All you need is your AC owner’s manual to understand how to complete this process. You can also use the manual to learn how to wire a disconnect box to your A/C.
- There are many types of thermostats. This variety means that not all thermostat settings will be the same when unlocking them.
Unlocking your Air conditioner thermostat is a super quick process that takes nothing more than a few minutes and the owner’s manual. And for those who may have other types of AC units, we have an article that covers how to use a portable air conditioner.
Unlocking an Air Conditioner Thermostat
STEP 1 Locate your User Manual and Find Unlocking Instructions
- Each thermostat will be slightly different, so you should have the manual handy in case there are slight variations on how to unlock your programmable thermostat.
Insider Tip
Many thermostats come with a “partial” lock setting. This setting allows users to keep some of the unit’s functions locked and others unlocked.
STEP 2Hold Down the Menu Button
- Scroll through the list of options, using the (+/-) thermostat buttons until you arrive at the option to select “Lock.”
- After finding the lock selection, hold down the select button.
- Choose “Off” if the menu lists that as an option. Other models may ask you if you want to lock the thermostat. If this occurs, press enter.
STEP 3Enter Your Code
- If you haven’t created a custom lock code, enter “1234.” This password is the most common default lock entry code. You will most likely have to use the +/- buttons to navigate the screen to the correct numbers to enter the password.
- After the code is typed out, hit “Enter/Select.”
- Your thermostat should unlock and be ready to program after entering the code. You will most likely see a flashing “-” symbol if the code is wrong. Call the AC manufacturer’s customer service line if you can’t remember your code.
- Once unlocked, adjust the settings and programs to meet your preferences.
Warning
With most thermostats, you’ll use the +/- buttons to navigate menu selections, but this isn’t the case for them all. Be sure to check your user’s manual before starting.
