  Your Daikin Air Conditioner might not be running due to several reasons: * The power could be off, or there might be a loose electrical connection. Check for the correct voltage at the compressor contactor in the control box. * The thermostat might be out of calibration or set too high. Try resetting it. * A contactor could have failed. Check for 24 volts at the contactor coil; replace it if the contacts are open. * Blown fuses or a defective transformer could be the issue. Replace the fuses. * The high-pressure control might be open (if provided). Check the wiring, replace the transformer, and reset. Note that the high-pressure control opens at 450 PSIG. * The low voltage wiring may be damaged. Replace the thermostat wiring.

  If your Daikin Air Conditioner isn't cooling enough, consider these potential causes: * The unit may be improperly sized. Recalculate the load. * There might be improper airflow. Check that it's approximately 400 CFM per ton. * The refrigerant charge could be incorrect. Charge it according to the procedure attached to the unit's service panel. * There may be air, non-condensables, or moisture in the system. Recover the refrigerant, evacuate, and recharge, adding a filter drier. * The voltage might be incorrect. Ensure the voltage at the compressor terminals is within 10% of the rating plate volts when the unit is operating.

What to do if the condenser fan runs, but the compressor doesn’t, in my Daikin Maverick I MPS A03C?

  If the condenser fan in your Daikin Air Conditioner is running but the compressor isn’t, here are a few things to check: * There might be a loose connection. Check for the correct voltage at the compressor and tighten all connections. * The compressor could be stuck, grounded, have an open motor winding, or an open internal overload. Wait at least 2 hours for the overload to reset. If it's still open, replace the compressor. * There could be a low voltage condition. At the compressor terminals, the voltage must be within 10% of the rating plate volts when the unit is operating. You can also add start kit components.
