Breaker trips on roof top RV A/C

We purchased EEZTire-TPMS for our new 33' travel trailer right before a 4500 mile trip through the upper Midwest to the Washington coast, so lots of different terrain. We experienced snow, freezing rain, dust, salt water and the temperature extremes associated. These monitored the pressures and temperatures very well.

The distance from the monitoring unit to the sensors was about 25ft and connected well. We did occasionally see a short disconnect with one sensor (maybe twice during the trip) that resolved after about 20 min. Overall these have worked Very well and I would recommend them to all RV travelers.

If it trips the circuit breaker as soon as you turn the FAN on, suspect either a bad fan motor or a failed fan motor start capacitor. If you are able to turn the fan on but the circuit breaker trips as soon as the COMPRESSOR starts, it is possible that the compressor is seized.
If, on the other hand, the unit is tripping a GFCI (Ground Fault Circuit Interrupter) breaker or GFCI utility outlet, it is possible that neutral and hot are reversed at the outlet into which the trailer is plugged (happened to me this year at an RV park).

What size circuit breaker is on the generator that is tripping? You'll need a 20amp for AC alone, then consider other things that are drawing current when RV plugged in like , converter, fridge etc that may be drawing current at same time. Make sure fridge is on propane, as well as water heater if you have electric element option on water heater. AC may only draw 12-15 amps when running if good and clean and wired properly, but will draw 17-18 amps when compressor kicks in. Perhaps generator not designed for that surge?

Hi, there are no reset buttons on the roof, but find the breaker panel in your RV, and you will find a breaker that is most likely tripped. You will need to reset it by turning it off and back on very firm. It should be about a 20 amp breaker. On the roof , there may also be a disconnect box with either a breaker or fuses also. Check the one inside the RV first, it is there somewhere. If it continues to trip the breaker, we will have to check to see if you have a problem with the compressor, condenser fan motor up top, and blower motor inside to see what is taking place. You may have a dirty coil up top that needs a good washing out as this will cause the unit to have high internal head pressures and will take out the compressor and keep tripping the breakers. Keep me posted on what you find and please don't forget to rate me as I know you will be kind. I will check back in with you on this to see how you are doing. It is 11:00p.m. here, so I will check on you in the a. m. This should solve your problem if you remove the top and make sure the condenser motor is running along with the compressor. Then kill the power again to wash this coil out. Please keep me posted.

if air only coming in then the fan ok but comp. not working

Current draw to high....BREAKER COULD BE WEAK..

I take it you have RV plugged into generator. Hopefully direct with no extension cords. Are you using a 30 to 15 amp adapter to plug into generator? What is the rating of the breaker on the generator that keeps tripping, suspect it's only 15 amp?

Clean the condenser could be tripping on high pressure switch or low pressure switch low on freon have leak fixed and recharged. Tom

you need to check that the breaker it rated high enough for the ac unit
