I have a window AC unit bolted to the bottom of the lower window sash, this prevents the lower sash from opening. Q: Is there a way to mount a window AC unit such that the lower sash is able to open/close? A new problem is the upper sash is doesn't "grip" the frame so it falls down and currently a piece of wood is in place to hold it up. Q: Given that the window AC unit "pushes" the lower sash up preventing the window latch from being an option, how else can I get the upper sash to stay up? Currently using eyelets and mini bungees but even after cinching, the mini bungees stretch after a couple hours and the window falls. Also the tenant is complaining about having to use the mini bungees and wants a more elegant solution. The solution can be short term since I've ordered new windows but those are several weeks out.

With thermostat set to off, the outside AC unit continues to run unless I disconnect at breaker box. When I reset breaker to ON, the unit comes back on unless I switch back to OFF at breaker. This is with thermostat in off position, or if it set to shut off automatically at set temperature. Condenser seems to still run/work ok except for not shutting off when its supposed to. The blower fan inside does not continue to run, only the outside unit. I tried testing the thermostat by pulling out the yellow Y wire at the tstat, and the outside unit is still running. (I have to disconnect the wire because my tstat is not the type that disconnects from the wall). From what I understand, this means its not a problem with the tstat and it is likely the contactor becoming welded shut? I just wanted to check if I am on the right track before going any further, and what would be the best way to check/test the contactor if that is likely the culprit. AC Condenser Model: General Electric Model 21TA936H1F This is a very old unit, from around 1968, but it has performed great for us and from what I understand these are built very well. We don't have the money to replace with a newer unit, and would rather continue to service where possible. Thanks
