The VFD has internal current measurement to protect PFC components from exceeding current thresholds that may shorten the VFDs operating life. If the PFCM Sensor B exceeds safe reliable value, the VFD will shut down immediately and attempt a restart after 5 minute compressor protection timer expires. Three occurrences of code 88-35 within a 4 hour period will result in 88-75 malfunction and 4 hour lockout. While this fault or malfunction is active the unit is inoperable. This malfunction, once set, is unlikely to go away and indicates VFD damage. Manually power cycle outdoor unit with disconnect, if malfunction persists replace VFD.
