I have a 9100 btu window ac which does not cool. Air from the duct is room
temp. I checked amps and watts using a Kill-a-watt meter. Specs say 7.3 amps
and 880 watts. I measure 3.3 amps and 272 watts. I used the same meter on a
5600 btu ac that we have in another room. Its specs are 4.9 amps and 510
watts. I measure 4.4 amps and 495 watts. This implies the meter is ok.
Does this low power draw in the 9100 btu unit indicate loss of freon (is the
compressor maybe running but not compressing anything?)
Sounds like the compressor is not running. You should be able to hear it
kick in when you turn the control from "fan" to "cool".
It could be a variety of things. If the Freon leaked out, it probably has a
safety to prevent it from starting. Could be the thermostat, the switch,
could be a capacitor. If the thermostat is sticking, simply turning the
know a couple of times may fix it. Anything else requires opening the unit
and checking stuff with a meter.
buffalo ny: if replacing it, remember the unit was too small, it took
too long to cool down the hot room upon arrival. upgrade to a bigger
unit most with remote control and digital temperature, subject to
window opening sizes, while air conditioners are still readily
available in spring.
I failed to mention initially that I had also checked electric draw with the
fan only. It was .81 amp and 90 watt so I think the compressor is running.
We have decided since the unit is 8 years old to buy another one and I will
store this one in my shop to play with later. You can pick up a 10000 btu
Sunbeam at Circuit City for $180 or so but I may look for a more efficient
and probably higher quality one.

Good idea. Window air really isn't consumer serviceable if freon is low.
You've got to sweat on valves usually just to get gauges on and some new
freon with dye in it so you can find the leak. By that time you've
surpassed what the unit is worth unless it's a really big 220 volt thru
the wall job.
