Fan high low switch

[nick]

I have a 2011 keystone outback and the fan for the AC seems to have only one speed "high" when I put it on low it doesn't seem to blow at all.
Any ideas would be greatly appreciated.

Which type of thermostat do you have? Analog or digital? Dometic or other brand?

The older analog Dometic's look like this:


Any of the digital thermostats will have an LCD display.

Our dealer recomended that we never use the low portion of the switch during the PDI on our first trailer, I remembered little fact after staring at what I thought was iceberg someone had stuck in my a/c unit. In your neck of the woods with the heat and humidity I forget about the low side and just turn the temp up a bit. IMHO

No disagreement with your thoughts, but if the OP is only getting fan on the HIGH position, there's no guarantee that it's even really HIGH. Might be LOW.

Best to sort it out and make sure it works correctly all around, and then make a conscious decision which setting to use based on location, outside temp, humidity, etc.
