  If your Daikin Heat Pump system isn't starting, there might be several reasons: * A fuse might have blown. Turn off the power supply and replace the fuse. * A breaker might have tripped. If the breaker knob is in the OFF position, turn the power supply ON. However, if the breaker is in the tripped position, do not turn the power supply ON. * There might be a power failure. Restart the system after the power is restored. * A connector might be loose or not fully plugged in. Turn off the power supply and check the connector.
