A/C flips circuit breakers

I'm running into a bit of trouble with my C Class.
1997 Jayco, 30 foot.
Today we were replacing the floor, A/C doing OK till the breaker flipped.
The humidity is high and it's 102.
Could it be just too hot for the A/C to handle or is it something more ominous ?
Had A/C checked by an expert.
New Cabin battery. New circuit breakers.

Welcome to irv2.
If you normally have a 30 amp shore line power cord than you need that 30amp for your AC because of its current draw.
If you have a Gen, run that and AC should run but use power tools off cord from a house circuit.
Here is some info that may help you for power systems in your coach.

Chris, the A/C expert should have been able to tell you how much amperage the unit is drawing when the fan by itself starts and runs, compressor is starting and after it's started. Also need to check to see if it's short-cycling and tripping the breaker perhaps due to the thermostat not allowing 60-120 seconds rest period before re-energizing the compressor - as the head pressure is still too high to start the compressor.

Happened to me not long ago.. 20 amp branch breaker for ONE of my A/Cs was tripping after a few minutes run time.

I went topside with ye-old screwdriver and popped the top.

Removed the inner cover on the Condenser (hot) coils.

Removed the CRUD that had accumulated on the coils.

Replaced covers

Problem solved.

I will definitely give everyone ones advice a good try.
We don't have a generator yet. The unit came without one and I'm looking at a Champion 3500 4000 as soon as I can.

I hope I found the problem, The coil is filthy.
I'll have to attack from above, I just hope I can clean it without breaking too many parts.
Especially mine.

Good luck . There may be specific a/c or radiator coil. Cleaners you can use to make it easier. Hope it works out for you.

I think I got it fixed.

Placed ladder with trash can to catch dirt and water.

I'll put more photos on next page.

I removed the A/C cover and opened the plenum by removing 10 screws and folding back the metal.

Soaked the coil with coil cleaner, then worked out the damaged blades by carefully working with blade tool. Slow and careful. Work it like you removing a splinter from you dogs nose.

I used a spray bottle to rinse the coil. That way I didn't blast water into the cabin. Also easier on the coils.

Ones I was done I sprayed the bolts holding the cover with some sealant spray.
Water was dripping from celing. There is a long blot that the water was following. I backed in out 1/2 inch and wrapped with Teflon tape. Once tightened it stopped the drips.

So, you are saying it no longer trips the breaker, it is working properly?

If so,, Thanks for letting us know.. I like it when I get the answer .

(Frankly, You would be amazed at the amount of work I put into SOME answers but in this one "Personal (and recent) Experience" had the answer.. It was last month I cleaned my front A/C because it was tripping breakers)

I hate it when I spend lots of time and money trying to fix something when all it needs is cleaning.

I ran the A/C all day. It was 102 outside. The breakers never flipped so I guess that was the problem.

Great work. Surprising that the AC tech didn't mention this issue when looking at it.
