Codes de défaut couverts
88-72
The VFD has internal temperature sensors to monitor critical power components and take action if operating temperatures cross thresholds that may shorten the VFDs operating life. Code 88-72 means the system can no longer monitor the IPM, which is critical for system operation. Inspect wire harnesses and terminals for pinched wires or insulation that has bare spots. If no problems are found and the code persists the VFD must be replaced
