RA R32 Split & multi split M-Series ESIE16-02B | The present publication is drawn up by way of information only and does not constitute an offer binding upon Daikin Europe N. Has compiled the content of this publication to the best of its knowledge. Explicitly rejects any liability for any direct or indirect damage, in the broadest sense, arising from or related to the use and/or interpretation of this publication. [. . . ] Replace the compressor if the windings and/or insulation measurements fail (refer to "Replacing compressor" on page 76). Run the compressor and measure the current in each phase; the current for each phase should be identical (refer to "Product specific information" on page 111). In that case it can be decided to preventively replace the compressor (refer to "Replacing compressor" on page 76). Electronic expansion valve
Technical specification
The electronic expansion valve has a hermetically sealed body with a slide-on stepping motor drive coil (480 pulses from fully closed to fully open position). Switch on the Daikin unit and listen to the expansion valve assembly, if the expansion valve body does not create a latching sound, continue with the electrical check. Slide the magnet (tool part N° 9950038) over the expansion valve body and gently rotate the magnet to manually operate the expansion valve body clockwise (closing) and counterclockwise (opening). If it is not possible to open the expansion valve body with the magnet, the expansion valve body is blocked and the expansion valve body must be replaced (refer to "Replacing expansion valve body" on page 81). Check if the electrical connector of the expansion valve coil was correctly connected to the PCB, if not, connect the electrical connector. Disconnect the electrical connector of the expansion valve coil and check the continuity between below pins using a multi meter. Com manuals search engine

RA R32 Split & multi split M-Series ESIE16-02B | Part 2. If one or more of the windings have no continuity, replace the expansion valve coil. Fan motor
Technical specification
The motor has a single connector for DC power and the rotation counter feed back from the integrated pulse generator (4 pulses/revolution). Description
The fan motor runs on a fixed speed to supply the required air flow rate. Check the state of the propeller, replace the propeller if damaged, deformed, cracked or broken (refer to "Replacing propeller fan blade assembly" on page 85). Check the motor shaft bearing friction, only perform electrical check if motor runs with low shaft bearing friction. WARNING: RISK OF FIRE
When reconnecting a connector to the PCB, do not apply force, as this may damage the connector or connector pins of the PCB. Check power supply, the measured voltage must be 198 - 240 VAC, if not replace main PCB (refer to "Replacing main PCB"
on page 84). Com manuals search engine

Technical specification
The pressure sensor is an analog pressure sensor. Description
The pressure sensor measures the pressure in the high pressure section of the refrigerant circuit. Connect a pressure gauge to the high pressure service port and read the pressure. INFORMATION
To know where to plug in the pressure sensor connector, see "Component checklist" on page 111. [. . . ] 0CuT
