I have a whirlpool window unit (no model # sorry) i'm guessing at least 15 years old. It was not used for a few years, started it up a couple weeks ago and ran it several times, it cooled same as always. Turned it on a couple days ago, and all i get is a hum coming from it, the fan tries to turn very slowly but thats it. I made sure i had voltage on both legs, checked the fan for obstructions, tried spinning the fan to get it going, no help. Looks like a pretty simple setup, the controls, a large capacitor (i'm assuming a dual cap thats for both the fan and compressor). The capacitor looks ok no buldging or anything like that. The motor appears to be sealed, no obvious place to oil it that i saw. Any ideas on where to start? Many thanks Rick

I have a carrier 2 1/2 ton 10 seer unit. What evaporator coil should be used for replacement. Can I use a 13 seer? Also, is American Standard aluminum coil a better coil?
