the indoor unit starts up as if the unit is fine then as soon as the compressor is about to kick in (after 10 or 20 seconds) the green light on the front of the unit starts flashing and the unit shuts down. went to outdoor unit and have 2 identical outdoor units next to each other. the one that is working correctly has a red and green light that are both on solid. on the broken unit they are flashing in a sequence. green green red red. any ideas what this means??

sounds like you have interlinking wiring problems, crossed wires or lose connections between s1 s2 s3 indoor to outdoor.
