Why can't I adjust the set temperature on my Friedrich MRM18Y3J Air Conditioner?

If you cannot adjust the set temperature on your Friedrich air conditioner, it may be operating in Auto mode. Temperature adjustments are disabled in Auto mode, so switch to a different mode to change the set point. Also, ensure your desired temperature is within the range of 61°F-86°F.
