I have a new Carrier Infintiy 4 ton heat pump. Everything is great with the new system except I get 46 Brownout failure codes. On the advive of my install team I had the electric company come out and put a reading device on my electric meter. It was on for a week and they show no low spikes. My install team has also checked all the connections to my unit. They have also replaced the board on the outside unit. I am still getting the failures, any ideas?
