Should an in-wall Air Conditioning Unit cycle on and off even when switched off?
First time Ive heard of a wall unit that is turned off, to actually turn itself on for a minute and then shut back off. It could be a system check of some sort, or maintenance feature… I’d suggest that you get the model number off the unit, and hit their website. At this link (their website) you can ask a question about your unit, – http://www.whirlpool.com/custserv/index.… or even get an owner’s manual (which could tell you what the unit is doing) at this link – http://whirlpool.custhelp.com/cgi-bin/wh… Good Luck!
