Question and Answers


kenmore window air conditioning unit not cooling


Your symptoms point to an air flow problem or a sealed system failure. You can clean the filter and the grill to try and maximize air flow through the unit. Here is a link for the owner's manual that shows that process: Owner's Manual for Kenmore Window Air Conditioner 580.74066400 . You can also try to clean that evaporator more thoroughly. Keep in mind that those fins are sharp.

Check the frost pattern on that evaporator. If you see an uneven or weak frost pattern, then you have a sealed system problem. Low Freon charge, a restriction in the sealed system or a weak compressor could be causing that type of failure. A service technician would need to diagnose and repair that type of problem. Here is a link for the Sears Service website in case you need it: Sears Home Services .

I hope that these tips help. If you need more assistance, reply with additional details.
