Check SiBE05-722_A
108 Service Diagnosis
4.1.9 Power Module Check
Check No.13
Note: Check to make sure that the voltage between (+) and (–) of the diode bridge (DB1) is approx.
0 V before checking.
Disconnect the compressor harness connector from the outdoor unit PCB. To disengage the
connector, press the protrusion on the connector.
Follow the procedure below to measure resistance between the terminals of the DB1 and
the terminals of the compressor with a multi-tester. Evaluate the measurement results for a
judgment.
Negative (–) terminal of
tester (positive terminal
(+) for digital tester)
DB1 (+) UVW DB1 (–) UVW
Positive (+) terminal of
tester (negative terminal
(–) for digital tester)
UVW DB1 (+) UVW DB1 (–)
Resistance in OK several kΩ ~ several MΩ
Resistance in NG 0 Ω or ∞
