A few times in the past month, the air conditioner hasn't come on right away when I lowered the thermostat and a couple of times it tripped the breaker if the fan was on high. I usually have it on low. But today, it has tripped the breaker 3 times. It has been really hot here today (103) but the RV is inside a barn so it usually doesn't get very hot. But, I cooked a big dinner tonight and it got really hot in here. The air conditioner tripped the breaker once while I was cooking dinner and then twice in the last ten minutes.
Any ideas what to check for?

We left it off for about 20 minutes and then when I flipped on the breaker, it stayed on, or it has for the last 15-20 minutes. It is getting cooler in here finally.

Maybe you have too many other high energy appliances running at the same time. Microwave, toaster, coffee maker, electric skillet etc.
Also suppose it is possible that the power coming in is inadequate. Ask if your neighbors are having issues.

Hi. What breaker are we talking about? You said it's in a barn, is the house breaker tripping? Is there a breaker on the outlet you're plugged into? Is that tripping? Is one inside the RV tripping?

It happened to me a couple of times. Turned out to be dirty/corroded connections on my main power cord. cleaned them off with some fine sand paper and problem went away.

Always, always check the voltage when operating an air conditioner. One like this, will let you see the voltage at a glance. Voltage below 105 will damage the unit. A delay before the compressor starts is normal and is done to protect the motor from starting against high pressure. Low voltage can be caused by a power cord that is too small or too long, as well as bad connections and other inadequate wiring. During a heat wave, the power company might deliver voltage that is lower than normal to add to the problem. With all that said, it might just be just too many appliances on at one time as stated above, but I wanted to stress that the a low voltage issue can cost you serious dollars. |

Microwave, toaster, coffee maker, electric skillet etc. Also suppose it is possible that the power coming in is inadequate. Ask if your neighbors are having issues. Only the tv and two ceiling lights on. That shouldn't be enough. We don't have any neighbors. Sorry, I thought I put that in. It's the 20 breaker inside the trailer. The barn breaker isn't tripping. Thanks, I'll check that. We haven't unplugged it in awhile. I'll let dh read this part. After that 20 minute break last night, the air conditioner worked fine all night. Dh thinks it "froze up" from it being so hot in here. But I'll have him read all this and check everything mentioned. Thanks! |

I also wondered what kind of barn it is. As the unit exhausts off hot air, does that air have anywhere to go? If the barn is closed in, that hot air will build up and be pulled back into the A/C causing it to have to work harder and possibly hitting the trip limit. After the outside temperature drops for the day or the heat dissipates, I can see it running normally again. If this is the case, you could add some fans to circulate the hot air out of the barn for fresh regular temperature air?
