SiBE041029EB CheckService Diagnosis 1005.13 Capacitor Voltage CheckCheck No.21 RX50/60G2V1B, 71 class onlyBefore this check, be sure to check the main circuit for short circuit.With the circuit breaker still on, measure the voltage according to the drawing of the model inquestion. Be careful never to touch any live parts.5.14 Power Module CheckCheck No.22Note: Check to make sure that the voltage between (+) and (–) of the power module or the diodebridge is approximately 0 V before checking. Disconnect the compressor harness connector from the outdoor unit PCB. To disengage theconnector, press the protrusion on the connector. Follow the procedure below to measure resistance between the (+) or (–) terminal of thepower module or the diode bridge, and the U, V, or W terminal of the compressor with amultimeter. Evaluate the measurement results referring to the following table.Multimeter(DC voltage range)(R18183)Negative (–) terminal of multimeter(positive terminal (+) for digitalmultimeter)Power module (+)orDiode bridge (+)UVW Power module (–)orDiode bridge (–)UVWPositive (+) terminal of multimeter(negative terminal (–) for digitalmultimeter)UVW Power module (+)orDiode bridge (+)UVW Power module (–)orDiode bridge (–)Resistance is OK. several kΩ ~ several MΩResistance is NG. 0 Ω or ∞
