GE Air Conditioner - 3rd Fan Speed

[Roosevelt008]

We have the GE rooftop AC and so far it works well. It says 3 fan speed settings and the thermostat shows 3 bars for fan speed. However I can only get it to work 2 fan speeds. Has anyone found the 3rd fan speed?

First and second bars light up but third bar does nothing. Tried all modes auto/on/fan only etc.

Thx

I would suggest to download the manual (if you don't have one) for the A/C. I have a GE window unit in my shop office area, and the bars for the fan are really Low, High, and Auto Fan speed, which most often the third bar doesn't seem any different than high, but when the temperature is close to the set point, the third bar setting allows the fan speed to toggle between high and low as needed (which is different than the "auto" setting which turn the fan off when the A/C is not cooling at all). So on mine not really three speeds, but three settings. Yours may be that way as well. ~CA
