Can anyone recommend a replacement for a Tecumseh AW506ET-089-A4 residential A/C compressor?
The compressor, which is over 7yrs old, is definitely bad. I have 240V going into the compressor; measured w/compressor access cover removed. I'm going to try & source the exact replacement as you suggest bigdaddy, but the question remains - Am I better off purchasing it outright to avoid the mark up, or will warranty issues (with whomever I have install it) cancel the logic in doing that?

Not trying to insult your intelligence, just making sure, have you checked the capacitor and contactor already? if you have, try ohming the compressor. set your meter to Ohms, DISCONNECT the power going to the unit, verify that it's dead, and take the 3 wires from the compressor loose. check the resistances from each wire to the other two. you should get three different numbers, the two lowest should add up to the highest, within a couple tenths of an Ohm or so. if this is not the case, or if you get "OL" between any of the wires, the motor has a short between windings, and is bad. If you do get the right numbers, scrape a small bit of paint to expose the metal on the compressor, and check the resistance between each wire and the metal...... you SHOULD get "OL" on all wires. If you get a resistance on any, your motor has shorted to ground, and is bad. if not, the only other problem you could have with the compressor that would cause a no start condition would be mechanical (Locked rotor due to bad bearings, etc.)
a contractor should warranty their labor to install a new compressor. the comp manufacturer will give the 1 years part warranty. some manufactures require installing dryers and replacing the contactor as well.
