Last night during the NE storm we were woke up by a noice in the kitchen. It was our Raised Vent going up and down. The outside REMP3 Remote Blower is not running. The only why I got it to stop was unpluging the power to the unit. It does not appear to be the remote switch. Off and On with the switch does nothing. I do not believe that the relay is the problem. I disconnected power and the unit still goes up and down. I remove motor cover and watch the motor upper and lower limit switches. They appear to be working. I took a look at the AC Phase Control Board and it does have some minor corrosion on it. Think that it is Control Board. Any suggestion on testing. I have a small ohmmeter.
