Not sure if this has been discussed, but we were able to avoid a very uncomfortable situation while out on our vacation. Short story - A/C stopped working and the unit gave 5 flickers from the green light. After reading the owners manual online, it was determined I had to bring it in for servicing. Not good. I called Tacoma RV and explained my situation. Luckily, after they made a few phone calls, the unit can be reset by taking off the screen (4 screws) and you can either disconnect the red or black wire's for about 30 seconds and it resets :D .

So, if you are ever half way through your vacation with 93 degree heat, a two and three year old and a couple of dog's and this happens, give this a shot.

Thanks Jim from Tacoma RV. Hopefully this will help any of you.

Happy Camping :) .

It has been discussed but normally people disconnect the power at the trailer battery and also disconnect the shore power. Then reconnect the battery and then shore power.

That sounds like a easier solution, thanks.

I had the same situation develop last weekend in Colorado near the Wyoming border at Dowdy Lake. Temp was in the high 80"s and midday Saturday the AC stopped working. We made it through the night without A/C and I called Lakeshore. They suggested disconneting shore power and battery as stated above. It worked! It appears that at some campgrounds when power demand lowers the voltage/amperage throughout the campground the Carrier unit will default and shut down to protect the compressor. You need to reset the circuit board to get it up and running again. The above steps will correct the situation and get you running again.

After the Carrier unit detects (I believe it is three) power interruptions such as a spike or loss of power, the unit enters "safe mode" and will not operate until it is reset in the manor listed above. One thing to keep in mind, if you keep your AC unit running when the shore power is unplugged from the campground connection, the unit will remember this until either it happens two more times or the AC and DC power has been removed from the Carriers circuit board. It is always best to have all electrical equipment turned off when connecting disconnecting the AC power.

Dont mean to drag up an old post but we had an issue over the weekend with our unit. Went out Fri. eve and setup the camper at our campsite. Set the air on 72. i noticed Sat that it just didnt seem to be cooling right, and the compressor didnt seem to be kicking off or on. I finally turned it off because I didnt want to burn up the compressor. Sun. started to get warm so the wife turned it back on, it ran for about 10 min. and then shut off. The green light started flashing but I didnt notice the number of times, I just turned it off. I called the closest rv dealer to me and they told me to pull the fuse out and let it set for a few min. and put it back in. I did that and it did come back on, but i dont want it to set out there and run while i see if its cooling and burn up the compressor. Should i let it run to see if its working or just take it in for service?

Ahh, Its MOD TIME! lighten


Note to self - Put in a switch on 12 v supply at A/C controls to kill power and reset......

No More going out in that hot, humid weather to disconnect power and battery.... :sweatdrop:

I have been having an ongoing problem this weekend with my ac unit shutting down. It does the 5 blink deal when it does. It seems to ru all night just fine. I cant figure it out. Has anybody taken these in for service? Whats it cost. A brand new unit is around 600.00. I have been just flipping the main powere breaker in the camper to reset it. That seams to work.

If it is tripping in the morning or late afternoon then it is a voltage issue at the campground. Monitor the voltage as you do not want to run the AC if the voltage drops below 108.

Only had to do this once, but it worked like a champ.

Were you plugged into shore power through a surge protector? Just curious if you would have to go through all this if you were using a surge protector. I am going camping this coming weekend, and I guarantee that we will have the A/C running along with 150 other trailers and RV's. If the surge guard detects a power drop, it cuts all power to the trailer from the power pole, leaving me on battery. Well, I know the battery will not support the A/C. When stable power is detected by the surge protector, it opens up and allows power back to the trailer. I assume that I would not have to reset the A/C, or would I? Hmmm.

Actually that will guarantee that you will need to reset it. If the compressor shuts down 3 times with out being commanded by the remote it locks the unit and will not allow it to start.

I did not know that, though I probably read it at some point in the manual. Thanks.

We had the same thing happen to us last week in 100+ heat - no AC and 5 blinks on the green light. I disconnected the shore power and battery, waited for a few seconds then connected it all back up. It worked and we didn't have a problem with the AC for the rest of the week.

Thanks for the posts. Camping right now at Silent Valley campground in So Cal. AC had the 5 blinking lights yesterday. Today I surfed the site looking for answers and here we are.

I disconnected shore power, disconnected the batteries, waited a few moments, hooked everything back up, and we are good to go !! AC memory reset and is back up and running !!

Happy Camping everyone ...
