If the DC voltage measurement is not within acceptable operating parameters the VFD will shut down and attempt a restart after 5 minute compressor protection timer expires. Three occurrences of code 88-33 within a 4 hour period will result in 88-73 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.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n<p class=\"has-small-font-size
