The reset button keeps tripping when I plug unit up

Need a new thermostat to keep the unit from tripping

If it runs in test mode but not during normal, there is a wiring issue.

You are tripping that outlet's breaker. Either too much is on that breaker and circuit or that circuit is not big enough, enough current to power that unit.

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

Testing

You should test the Arc Detection Device
equipped power cord monthly, after every major
electrical storm, or if power to your Room Air
Conditioner has been interrupted.

Follow these steps to test the Arc Detection
Device:

1. Unplug unit from electrical outlet
2. Press the reset button
3. Plug the unit back into electrical outlet
4. Press test button. Unit should trip and reset
button will pop up.
5. Press reset button again for use
If above test fails, stop using the air
conditioner and contact customer service by
calling the following toll-free number:

I hope this helps & good luck!

Hi,
There is nothing you can do to fix it... the compressor is trying to start and cannot so it trips the plug. The plug trips to protect the house circuit from being overloaded and causing a fire.
Getting the compressor replaced is cost prohibitive, it is cheaper to buy a new unit.

Do you have anything else on the same circuit? I have heard about many of these units, not just Fedders, that will not run on a circuit that has another appliance or something that is pulling a lot of amperage. Also, check and make sure the receptacle is not worn and the plug is loose fitting. Other wise, you definitely could have a weak internal connection in the cord. Hope this helps.

Hello,

Welcome to FixYa.

To answer your question "where is the reset button?" I`d direct you to the back...if you haven`t already.

It will look like this...



If you push this to reset and the unit works, great. I would keep an eye on it though since the hi-limit typically trips for a reason such as a plugged lint filter, plugged vent ot partially plugged or the heater itself is plugged up with lint.

Take the lint filter and clean it under some warm water and soap as they do become plugged with wax over time due to fabric softener and static sheets.

If it doesn`t heat or start after-wards or it`s not tripped, you`ll need to investigate for a faulty heater element.
This is quite involved, so we`ll cross that bridge when you get there...if necessary.

Keep me posted on your progress or what you find.

Good luck.

There's obviously there is a short or electrical overheating problems omewhere in the appliance that's causing the circuit breaker (Reset Button) to trip. Stop using the AC unit and have it checked by a professional.

This is only a 5,200 BTU unit - for single room use.

If you're sure the voltage ok, it sounds like the unit is new and should be under warranty.

The reset button is a voltage leak detector it is possible the unit has a short in it or the cord has a short
