  If your Mitsubishi Electric Air Conditioner unit isn't operating, there are several potential causes: * The main power might not be turned on. Ensure the power is switched on. * The pump interlock circuit or the flow switch wiring may not be connected. Connect the pump interlock circuit wiring and the flow switch wiring to the system. * There might be a short-circuited circuit or ground fault. Resolve the cause and replace the fuse.

  If your Mitsubishi Electric Air Conditioner is running, but the water isn't heating up in cooling mode, it could be due to several reasons: * Water flow shortage: Increase the water flow rate. * The water-cooling load is too high: Install more units. * Low refrigerant charge: Perform a leakage test, repair the leaks, evacuate the system, and charge the refrigerant circuit with refrigerant. * LEV fault: Replace the LEV in the main circuit. * Compressor failure: Replace the compressor. * High or low pressure: Operate the units within the specified pressure range. * Problem with the external devices: Repair the devices.
