User manual TOSHIBA RAV-G1003HE8 SERVICE MANUAL

[. . . ] If an above action is executed during the fan operation, the protective control works to stop the unit operation, and the check code "P12" may be issued. When the desired operation has finished, be sure to reset the system to clear "P12" error code using the leak breaker of the indoor unit. Then push the operation stop button of the remote controller to return to the usual operation.

[. . . ] Is not coil winding between 1 (Yellow lead) and 4 (Pink lead) opened or shorted?5 to 20kW Is signal output of indoor fan motor position detection correct?*3 YES NO Replace indoor fan motor. *3 Check fan motor position detection signal. · 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. 2007 [P22 error] Are connections of CN301 and CN300 of P board correct?YES Does the fan rotate without trouble when handling the fan with hands under condition of removing CN301 and CN300 from P board?YES The status that the resistance values between leads below are 50 to 80W for 40W motor (ICF-140-40) and 25 to 55W for 60W motor (ICF-140-60-1) is normal. Between 1 (Red lead) and 2 (White lead) Between 2 (White lead) and 3 (Black lead) Between 3 (Black lead) and 1 (Red lead) of motor winding of connector (CN301) YES The status that there is 5k to 20k resistance values between 1 (Yellow lead) and 4 (Pink lead) of motor position detection of connector (CN300) is normal. YES CN300 : Motor coil winding CN301 : Motor position detection NO NO CN301, * CN303 NO CN300 *CN301, CN303 : Motor coil winding CN300, CN302 : Motor position detection SM110, SM140, SP56, SP80, SP110, SP140 Normal fan motor (Control or CDB P board) . C. YES NO Correct connection of connector. * (For RAV-SM563AT-E, SM803AT-E, CN601 TD sensor) NO Replace TD sensor. Check control P. C. Defect Replace ® * Refer to Characteristics-4. [F08 error] Is connection of TO sensor connector of CDB CN601 normal?YES NO Correct connection of connector. * (For RAV-SM563AT-E, SM803AT-E, CN602 TO sensor) NO Replace TO sensor. Check CDB. Defect Replace ® * Refer to Characteristics-5. ­ 95 ­ Revised : Mar. 2007 [L29 error] Are connections of CDB CN800 and CDB IPDU CN06 connectors normal?NO NO Correct connection of connector. YES Are cabling/connector normal?YES NO Check cabling between IPDU and CDB and connector. IPDU P. C. board error Defect Replace ® YES Is there no abnormal overload?YES NO Improve and eliminate the cause. Correct mounting. IPDU P. C. board error Defect Replace ® [H02 error] NO Is power voltage normal?YES NO NO NO Improve power line. Check and correct circuit cabling such as cabling to compressor (phase missing) and connector. Compressor lock ® Replace ® ® Check TE and TS sensors. [. . . ] Attach #250 Faston and UL-approved sleeves each to the end of lead cables which are connected to the thermostat. 2-5 Thermostat fixing plate Cord heater * Transparent L side P-shape clamp Fuse Fuse holder Using insulation tape, apply protective measures to the connected parts by the close-end connectors. Using P-shape clamp and the screws (Selftapping screw type-B Ø4 × 8mm), fix the power cord to the thermostat fixing plate. When the power cord size does not match with Pshape clamp, procure the most appropriate one at the local site. ­ 189 ­ No. Photo / Explanatory diagram Procedure 3 Assembly Return a set of the refrigeration cycle assembly into the outdoor unit base plate and reassemble sound insulation board, partition plate assembly, fan motor assembly, and side cabinet (R/L) as original. Fix the thermostat fixing plate to the side cabinet (R), built in the inverter assembly, and then connect various cables. [. . . ]
