Power module checking
When using the digital type of multiple tester, make measurement in diode check mode.
*There needs to be none of each value variation.
The following abnormalities are also doubted besides the PC board abnormality.
• Faulty compressor (ground fault, ground leakage)
• Faulty fan motor (ground leakage)
