AC flipping the breaker repeatedly


Hi everyone, thanks in advance for your help.

I installed an 11,700 BTU air conditioner in my apartment about 6 years ago.

My apartment has a few breakers, including one for the bedroom upstairs, one for the fridge, one for the "west wall" where I have a good amount of computer and audio equipment, and one for the corner of the room, where the AC is, along with a few small components connected to the TV - an 80w radio, a hard drive, and a few low voltage networked audio devices. All these devices and the 32" TV are connected to the same circuit as the AC.

All was good until about 2 summers ago, when the AC would occasionally flip the breaker. Over the course of last summer, it started to flip more often, and in the current heat wave is now flipping the breaker ever 20-30 minutes. It also takes out the lights in the kitchen for some reason.

My thinking is that either the breakers gone bad, or the AC is going bad and drawing way too much power. I've uploaded some pictures of the AC power requirements and the breaker box in question below - note that the switch that flips is part of the pair in the lower left, the top "20" switch. Keep in mind that when the switch flips, only the top switch in that pair needs to be reset - the lower 20 switch is unaffected.

Thanks in advance for any advice about the best way forward!

Call your landlord and have them get the electrician to come out and replace that breaker and that breaker you posted on bottom left that is not a correct one for that panel.

So therefore let the landlord call the electrician to fix this one.

Sound like the breaker is getting weak so it will need a new one.

Merci,
Marc

My guess is that the compressor is starting to go on your AC.

The other thing if I remember right when the starting capaitour go bad it will cause very hard staring and many time it will trip the breaker.

Did the breaker trip rightaway when the window shaker start up or it trip in couple minuites after the window shaker running ?

That kind question should able give us the answer.

Merci,
Marc

it usually takes a little while for it to trip.

the breaker will trip, ill reset it, and the ac will run for between 10 and ~120 minutes. then the breaker trips again.

setting the ac to lower temperatures seems to trip it more often.

we took the unit out of the wall when it was leaking water about 2 years ago, cleaned the inside. filter has been washed in the last few days.

sounds like i need to bother my landlord to get an electrician in here.

thanks for all the help, everyone.
