We have a 2018 Jayco Northpoint. We have 2 control panels in our RV to control AC and Heat, one in the kitchen (for 1 AC and Furnace) and 1 in the bedroom for the 2nd AC. Today, we are hearing what sounds like a 'fan' on in the bedroom although the control panel is in the off position. When we cycle through the different settings, we hear the unit respond, i.e. 'Fan Lo', we hear the fan come on low, 'Fan Hi', we hear the fan come on high, AC comes on when we select Cool lo and Cool hi. Yet, when we turn the control panel to 'Off', it sounds like their is some low fan on. When we turn off the circuit breaker, the sound goes away. and when we turn the circuit breaker back on, we hear it again. Any ideas what it might be?
