A few weeks ago, after a power outage, it did not resume normal operation. In the past it always has.
The fan is not working. Getting e f code. I disconnected the fan.
The plug feeding the fan has:
-12v DC when testing brown to red and also brown to yellow
-28 AC volts brown to red and brown to yellow
The fan disconnected has 1.7 ohms
The fan will spin when I jump 12 volts to it directly.
