Troubleshooting Diminished Fan Speed With An Atwood Air Conditioner System

Question:

Fan speed has diminished to running on low pretty much all the time. But sometimes will kick back into high where we want it. Any thoughts?

Hey Eric,

There really isn't much you can do to troubleshoot the fan on your air conditioner besides ensuring that it has the correct voltage running to it and keeping the shroud clean so that the unit can breathe. The fan going down to low on its own could be a power issue, or just some sort of communication error that you won't be able to fix without just replacing components, which are going to be hard to find since the Atwood brand has pretty much been discontinued at this point.

I would check the voltage # PT89ZR to the thermostat to see what it's reading and check to make sure you don't have the thermostat set on a timer that could be causing the fan to go to a lower setting. From there you'd be looking at replacing the entire system. If this is the route you have to go then I recommend the Furrion Chill HE RV Air Conditioner System # FR55PV.
