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.

Hello, anytime the unit does not blow out cool air I like to start with checking the airflow, check the filter and the evaporator coil for a buildup of dirt. If that check out ok then either the unit has a refrigerant leak or the compressor is not operating if the compressor is running than the unit is low on refrigersnt and can be recharged. In order to recharge the unit a piercing valve must be installed on the low side of the system, most window units do not have valves so one must be added to be able to charge the unit.
If you can take out the thermostat, check to see that you have power on both connections. If not it may be a bad t-stat. If you can jump the terminals on this with at least a 12 awg wire and it starts, then thats the problem. If you do have power thru the t-stat then it may be the relay on the compressor. It will usuallly look fried if it's bad. Pull it off carefully (with unit unplugged). With an ohmeter, touch one lead to one of the three post on the compressor and one lead to the housing. Do this for all three. If you get continuity on any, the compressor is toast.
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.
