[. . . ] Defect Replace 57 [P12 error]/[11 error] Turn off the power. Are not there connections errors or disconnection on connectors CN333 and CN334 of indoor unit P. C. board (MCC-1402). YES Correct connection of connector. Does the fan rotate without trouble when handling the fan with hands?YES Are resistance values between phases at fan motor connector CN333 motor side of indoor P. C. *1 YES NO Replace indoor fan motor. NO Replace indoor fan motor. *1 · Are not coil windings between 1 (Red lead) and 3 (White lead), between 3 (White lead) and 5 (Black lead), between 5 (Black lead) and 1 (Red lead) opened or shorted?35 to 60 · Is not earthed between cabinet and 1, 3, 5 10M or more Is resistance value of fan motor connector CN333 at motor side of indoor P. C. *2 YES NO Replace indoor fan motor. *2 Check resistance of fan motor position detection circuit. Is not coil winding between 1 (Yellow lead) and 4 (Pink lead) opened or shorted?5 to 20k NO Replace indoor fan motor. Is signal output of indoor fan motor position detection correct?· Using a tester, measure the voltage between CN334 1 and 5 of indoor P. C. board (MCC-1402) under condition that CN333 and CN334 are mounted and the power is turned on. Rotate the fan slowly with hands, and check the pin voltage swings between 0 to 5V voltage. Defect Replace 61 [P29 error]/[16 error] Are connections of cable/connector normal?YES NO Check and correct circuit cabling such as cabling to compressor. NO Is compressor normal?(Is resistance between windings 0. 6 to 1. 2 ?) NO YES Is not winding opened?NO Compressor error Replace YES Compressor error Replace Compressor error Replace Check IPDU P. C. board. [H03 error]/[17 error] Are cablings of power and current sensor normal?board. 62 [F06 error]/[18 error] Are connections of TE/TS sensor connectors of CDB CN604/CN605 normal?YES NO Correct connection of connector. * (For RAV-SM560AT-E, CN600 TE sensor and CN603 TS sensor) NO Replace TE and TS sensors. Check CDB. Replace Defect * Refer to Characteristics-3. [F04 error]/[19 error] Is connection of TD sensor connector of CDB CN600 normal?YES NO Correct connection of connector. * (For RAV-SM560AT-E, CN601 TD sensor) NO Replace TD sensor. Check control P. C. Replace Defect * Refer to Characteristics-4. [F08 error]/[1b error] Is connection of TO sensor connector of CDB CN601 normal?YES NO Correct connection of connector. * (For RAV-SM560AT-E, CN602 TO sensor) NO Replace TO sensor. Check CDB. [. . . ] 2) Remove the air-outlet cabinet, and then put down it directing the fan guard side downward. (ST1T Ø4 × 10, 2 pcs) 6) Remove hanging hook of the fan guard by pushing with a minus screwdriver. 2. Attachment 1) Insert the extrusion at the upper side of the fan guard into the square hole of the air-outlet cabinet, and then insert the hanging hook. Fix the hanging hooks (5 positions) by pushing with hands. Air-outlet cabinet Minus screwdriver Fan guard REQUIREMENT Check that all the hanging hooks are fixed to the specified positions. [. . . ]
