Comments & Questions

Victor Seguin
Lost power to outside compressor and now that the unit is hook up, E1 message and doesn't turn on
Answer
E1 on these mini-splits is a communication alarm: the indoor unit is not seeing the outdoor unit. Kill power at the breaker for 5 minutes, then check the interconnect wiring terminals at both ends and that the outdoor breaker is on. If E1 returns, it needs a technician.
