Why is my Daikin Maverick I MPS H05C unit not running?
- Eelizabeth29Aug 8, 2025
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.
