Hello,, I have a fedders window unit,
Series 6X07F2B i cant find tech info any where .
the compressor turns on when i power on the unit but the fan does not turn , no nothing
as well no cool air , and keeps turning off
is there any info online onwhat is wrong ? or how to take front off and inspect inside ?
Thanks in advance

Re: FAN ISNT TURNING ?
You won't see much when you take the front off just the evaporator coil and air output ducting. You'll need to remove the whole back cover to get at the workings. The evaporator and condenser fan are one motor with a double shaft. the double shafted motor may have dry bearings - they are oil-lite bearings, sintered bronze set in a felt holder. there may be a small capacitor on the outside of the motor. with the back cover off, locate the wires going to the motor. if you have a meter to read voltage, proceed. If you have no meter STOP, visual inspections won't get you very far. the motor probably is a multispeed motor. If you are squeemish about taking voltage measurements don't go any further. Get someone with knowledge of electricity.

you can check your heat pump on the outside by turning off the power and listening to see if it makes a whoosh sound. and then turn it back on you should hear it kick in. Is the outside unit running? Sounds like an electrical problem maybe in the breaker or the contactor on the inside of the unit. This is where the 24 volts from the thermostat call to the 240 volts to kick on the condenser fan and compressor. Be real careful in messing with this because of the high voltage.
Oh, the compressor motor's borked or overworked and overheating, or its capacitor failed short (perhaps the motor is shutting off from thermal shutdown...but you get to find out whether that's so. Be safe.) Alternately the temperature sensors have gone touchy on you. Once you gently vacuum it clean, try keeping incandecent bulbs in series with the compressor to get an idea of how loaded that thing is as it runs for those 5 minutes or so; the load might change more than you expect, just pay attention. Hopefully you won't have to replace the compressor or motor; but it's doable if you're a certified technician with like equipment (so you can handle the refrigerant decently.) Most shops will streamline a bunch of similar jobs together to cut the waste and setup time. Bigger conditioners are so much more efficient than little ones...syndicate the A/C?
I would try to start the unit with only the fan running at first. If it stays running then cycle on the compressor and see how it does. If the unit does not operate when compressor is turne on then we have to dig deeper into that.
