You may need a clean air filter, there may be a refrigerant leak, or the fan may have malfunctioned. An HVAC technician can determine the exact nature of the problem and make replacements or repairs.
Some air conditioning systems have a reset switch, which is a small, red button. Typically, the button will be on the outdoor unit. If you have a problem locating it on the outdoor unit, you may find relevant details on the equipment's manufacturer's manual. Press the red button for three seconds and release.
For the Honeywell Home app: Select the thermostat, press the Schedule icon, choose Options, then Turn Schedule Off. For the 8000 series thermostat: Press the "Sched" button, select "Edit," choose the days and period to clear, then select Cancel Period to clear the schedule.

Most modern thermostats will have a clearly marked reset button inside the panel. It's usually small and recessed, so you might need a pointed object like a paperclip to press it.
To do this, you can go to your settings on your thermostat, and you'll see a menu for the home and away setting. There, you can set the temperatures, times, and days you want the program to run. When you're done choosing the details of the program you want to set, press “set schedule,” and it will automatically set it.
In some cases, clogged air filters or dirty evaporator coils can also restrict airflow, forcing the AC to compensate by running at high power. To resolve this issue, it's recommended to check for clogged filters, clean coils, and consider having a professional inspect and repair the motor or fan control components.

The fastest way to see your thermostat model number is to look for it on your thermostat ID card. If you do not have a product ID card, the fastest way to find the model number is by removing the thermostat from the wall-plate.
Use the Reset Button on AC Unit
Don't worry; the reset button might be able to solve the issue after a sudden disconnection or power outage. You can press the “Reset” button on the air conditioning unit, often shown as a small red button, to bring your air conditioning unit back to life.
Check the thermostat
You should check if it's been set to the correct temperature and also make sure it's set to “cool”. If the AC settings are not right, it won't turn on. You can also check if the batteries in the thermostat are fresh and replace them if needed.
Turn off your air conditioning system. Locate the reset button on the thermostat's circuit board. Use a soft bristle brush to gently remove any dust or debris that may have accumulated on the thermostat components. Press and hold the reset button for 5-10 seconds until the display goes blank.
To permanently ignore the schedule, press up or down until the desired temperature is displayed. Then, press the Hold button to maintain the new temperature indefinitely. The word Hold will appear on the screen. Press the Run button if you wish to cancel either override and resume the schedule.
If your thermostat is going into recovery mode when you did not set the temperature to change in an hour or two, something may be wrong. In some cases, recovery mode happens because your thermostat has changed its settings. This can be an electrical glitch, user error or a problem with the thermostat itself.
