  If the compressor and fan of your Carrier Air Conditioner's outdoor unit won't start, first, ensure the unit is energized by checking the main power connection. Then, verify that the main switch is in the ON position and that the main switch fuses are not blown; replace them if necessary. If the compressor cycling protection is active, wait for 3 minutes. Also, check that the main power voltage is correct and that all electrical connections are secure and properly connected.

  If the compressor in your Carrier Air Conditioner runs continuously, it could be due to several reasons. First, check if the indoor temperature setting is too low or too high. A faulty outdoor unit fan could also be the cause, requiring replacement. Additionally, obstructions at the air intake or dirty indoor unit filters can lead to this issue; remove any obstructions and clean the filter. In some cases, the unit may be too small for the application requirements, and you should contact a qualified service technician for a system evaluation. Air or other non-condensable gasses in the circuit can also cause this issue, requiring you to drain refrigerant, evacuate and recharge the system.

  If the suction pressure of your Carrier Air Conditioner is too low, first check the indoor temperature setting to ensure it is appropriately adjusted. The issue might also stem from an evaporator coil covered with ice, indicating insufficient air circulation that needs checking and repair. Additionally, a clogged expansion device or suction line could be responsible, requiring inspection and repair. Inspect the electrical parts to ensure the outdoor fan stops during defrost periods.
