Airtemp Air conditioner wall thermostat not working properly
If your Airtemp air conditioner wall thermostat is not working properly, start with the thermostat itself. A failed wall thermostat or WiFi thermostat can have power but a dead display, fail to call for cooling, or stop sending the correct 24-volt signal to the air conditioner, furnace, air handler, or heat pump. If the thermostat display is blank, check for replaceable wall thermostat batteries next, since many thermostats use battery power or backup batteries. If the batteries are good, the problem may be a failed Airtemp air conditioner control board that is not supplying low-voltage power, an incoming power problem such as a tripped breaker, blown fuse, or unplugged unit, or a bad transformer that has input voltage but no 24-volt output. These issues can make it look like the AC thermostat is not working or the thermostat is not controlling the air conditioner. Enter your Airtemp model number on RepairClinic.com to find the exact wall thermostat, WiFi thermostat, control board, transformer, or related replacement part that fits your specific air conditioner.
01 - Airtemp Air Conditioner Wall Thermostat
The wall thermostat is responsible for controlling components and regulating the home's temperature. The thermostat can be powered with 24 volts from a control board on a separate unit, like a furnace or air handler, or from batteries in the thermostat itself. The thermostat also has terminals to receive and distribute low voltage 24 volt power to run different HVAC products such as a furnace, air conditioner, or heat pump. If the wall thermostat is receiving power but the display is dead, or it will not send power out in the appropriate modes, the wall thermostat will need to be replaced.

02 - Airtemp Air Conditioner Wifi Thermostat
The WiFi thermostat is responsible for controlling components and regulating the home's temperature. The thermostat is usually powered with 24 volts from a control board on a separate unit like a furnace or air handler. The thermostat also has terminals to receive and distribute low voltage 24 volt power to run different HVAC products such as a furnace, air conditioner, or heat pump. If the WiFi thermostat is receiving power but the display is dead, or it will not send power out in the appropriate modes, the WiFi thermostat will need to be replaced.
Highly Likely
03 - Wall Thermostat Batteries
Most wall thermostats are either powered by an enclosed battery or by the air conditioner's control board. If the thermostat display is dead, you can remove the thermostat cover and look for replaceable batteries. Replace the batteries if needed and check operation.
Common
04 - Airtemp Air Conditioner Control Board
The control board regulates the power supply to all of the components in the system. If the control board fails, it might not send voltage to the thermostat, leaving the thermostat inoperable.
Less Common
05 - Incoming Power Problem
Check to see if there is power to the air conditioner. One or more indicator lights on the control board should be illuminated. If there is no power to the air conditioner, check to see if a circuit breaker has tripped or a fuse has blown. Confirm the unit is plugged in and has power.
Less Common
06 - Airtemp Air Conditioner Transformer
On some air conditioning units the control board sends a low voltage signal of 24 volts to the thermostat. When the thermostat's contacts close, a 24 volt signal is sent to the appropriate unit and components. Some air conditioners may have a separate transformer for the 24 volt circuit. If the transformer has the proper input power but no 24 volt output to the thermostat, the transformer will need to be replaced.
Uncommon But Possible
