5. Method of Replacing the Inverter’s Power Transistors
Modules
Warning
: CAPACITOR SHOCK HAZARD. The capacitors (top surfaces) can hold up to 220V. Use
correct precautions when servicing.
Checking failures in power semiconductors mounted on inverter PC board
Check the power semiconductors mounted on the inverter PC board by the use of a multiple tester.
<Items to be prepared>
Multiple tester :
Prepare the digital type of multiple tester with diode check function.
<Preparation>
Turn OFF the power supply. Then, after a lapse of 10 minutes or more, make measurement of
resistance.
To make measurement, disconnect all connectors and terminals.
