5-44 powermax 65/85 Service Manual
For operational fault codes 0-40-0 and 0-40-1 or power board faults 3-11-0 and 3-11-1 (CSA only)
1. Remove PFC temperature sensor connector (J16) from power board.
2. Check the resistance between pins 1 and 2 on the plug. Resistance should be about 5.5kΩ.
3. If the resistance is incorrect, replace the PFC IGBT, gate drive wires, and PFC temperature sensor wire.
4. If the value is correct, measure resistance between pins 1 and 2 on the power board with the temperature sensor
disconnected. The resistance should be about 4.7kΩ.
5. If the value is correct, replace DSP board.
6. If the value is incorrect, replace power board.
