I HAVE A FEDDERS AIR CONDITIONER MODEL AED24E7F-C THIS UNIT TRIPS THE RESET BUTTON ONCE IN A GREAT WHILE IT RUNS FOR HOURS OR DAYS ON END AND THEN TRIPS. IT TAKE AWHILE AFTER THAT BEFORE I CAN RESET IT. THEN IT WILL RUN AGAIN FOR QUITE AWHILE BEFORE IT TRIPS AGAIN. IT SEEMS TO BE HAPPENING MORE OFTEN NOW, THIREE TIMES THIS WEEK. WHERE AS BEFORE IT WOULD RUN FOR A YEAR WITHOUT TRIPPIN

The reset button is part of the cord. The cord has built in arc detection. This is a complex circuit that monitors the unit and senses potentially dangerous sparks or arcing inside the internal components of the A/C (motors, switches, etc.) It sounds like the problem is getting worse - as they usually do. Sparking and arcing happen when dirt, corrosion, etc. accumulates and can result in pitted contacts. All of these conditions only make the sparks and arcs worse. Page 1 of the manual (left column) says this:

If the Arc Detection Device has tripped, the
reset button will pop up.

Follow these steps to reset the Arc Detection
Device:

1. Unplug unit from electrical outlet
2. Press the reset button
3. Plug the unit back into electrical outlet
4. Check to see if power has returned to the unit
