I'm having issues installing SoftStart on my 2019 330RL MHC 5er, rear AC unit. The rear AC unit on my RV is a Dometic Blizzard.

The SoftStart tech says my connections are correct, but it's not working properly. First, after several minutes running the AC compressor shuts off. Secondly, instructions say the SS green light should be glowing but I have a green AND center red light glowing ((I have meticulously checked every connection). Third, with nothing else on, current draw is 25 amps and it will not run on one 2000 watt generator (sea level altitude).

I'm waiting to hear back from the SS tech. If I can't resolve this, then I'm going to have to remove SoftStart and restore my AC wiring back to original setup. Has anyone else had this issue with a Dometic Blizzard and SS?

Something is not right. I wonder if the SS wiring diagram is correct or if the SoftStart is defective. Has anyone had this issue or anyone successfully installed SS on a Blizzard?
