Call Fedders' customer service line at 1-800-332-6658 to find a service technician in your area. If your Fedders AC has a serial plate rating of 115 volts and greater than 7.5 amps, it must have a dedicated fuse and circuit breaker.
If your Fedders air conditioner was in perfect working order before this little blip, do not call the repair technician just yet. The problem may be easy to fix. When your Fedders air conditioner fails to turn on, the problem is electrical. There could be a hiccup in the electricity supply from your home or something interfering with the air conditioner's working order. To help identify common problems, Fedders recommends a few home troubleshooting techniques. If these do not fix your problem, then you'll want to call in a professional. Further tampering may void your warranty or damage the unit.
Examine the power cord for signs of physical damage. If you find damage, call a technician to have the cord replaced. Do not attempt to operate the unit until then. If there is no damage, move on to Step 2.
Remove anything that obstructs the AC's air intake. The blockage may be causing the unit to overheat in which case the AC will automatically shut itself off. Allow the Fedders AC to cool for 10 minutes, then attempt to turn the unit on again. If this does not solve your problem, move on to Step 3.
Check to see if the reset button has popped up. If it has, the arc detection device was tripped. Unplug the Fedders AC. Depress the reset button. Plug the unit back in. Turn the unit on. If this does not fix your problem or the reset button did not pop up, move on to Step 4.
Turn the unit off via the master control switch. Unplug the power cord, then plug it back in. Jostle the plug slightly to check the connection. If it is quite loose or the plug easily slides out, a poor connection is likely the cause of the power failure. You must replace that wall outlet or plug the Fedders air conditioner into another outlet. If the outlet is not the problem, plug the unit back in and move on to Step 5.
Turn the master control to "high fan." If the fan does not respond, the problem may be your home's electrical supply. Unplug the AC and plug another electrical appliance into the outlet. If the second appliance also fails to operate, the problem is a tripped circuit breaker or blown fuse. Reset the circuit breaker or replace the fuse. Then try to turn the AC unit on again. If that does not solve your problem, it is time to call a repair technician.
