I turned my air conditioner and nothing happened...why?

Actually, I know the difference between the two since 1967.
It wasn't necessary for my conversation to delineate them.
The fuses are on the right side of the panel, and the 5 breakers are on the left.
Because thermostat isn't working and seems to be the source of the problem, I tested the fuses and found the two that are bad.
Thank you for your input, and to assure you, I'm not confused about which is which.

It wasn’t a breaker or fuse problem for me, but I once had my AC not come on after a winter storage period and it was due to the fan motor being locked up... I removed the cover, reached in and manually spun the fan and that freed it up and it ran as normal after that...I did later lubricate the motor and bearing.

[gcharles]

thank you for that insight...I'll make sure that my fan and bearings are lubed on the A/C unit up top. The previous owner wasn't as meticulous as the first owner was. I'm finding the little thing that show that. I know that he had kids because they left behind a lot of the kid stuff, and the previous owner was a younger guy and seemed to be in a hurry to get out of this camper...he also left behind an expensive coffeemaker and some waste cans too.
I'm hoping that the two fuses are the problem, but if they blew because of the fan motor not turning, then I have to go up to the roof unit and spin it, and lube it.
Thank you again.

Guess what I did while my lunch was in the microwave to get warmed up?
I dug out all the paperwork that came with the camper...and it has several papers explaining the thermostat, A/C, furnace and everything else.
I have a Shurflo 12 volt pump for my holding tanks, a MagneTek power center (120 and 12 volt systems), a Coleman 6799C6951 analog thermostat, and a Coleman 7000 series A/C unit. There's more for each aspect, like operating the slideout and the awning.
Each of the major units has a wiring diagram, and a specific detailed explanation of how each thing interacts together.
My A/C return grill is 14" x 14" and has a foam insulator, as I was told.
Yay!!

OK, but I was simply quoting your own words. If you aren't accurate in your terminology, then we either think you don't understand and/or we can't provide correct help.

I took off the inside intake cover and manipulated the fan from the inside to get it going.

gcharles, Bear with me. I'm still having a problem with your cords. Lets talk in terms of "Coming into" your camper.

The original service was 30 amp 120 volt w/30 amp cord. It came inside and connected to your 30 amp panel main 30 amp single pole breaker just as all rv's do right?

So know you say you have a second cord coming in. Where does that second cord connect inside your panel? You said the second cord supplies 1/2 of the camper. Do you have a 2 pole 30 amp main breaker? If so, the PO changed out the panel to a standard split buss panel but I don't understand why a 50 amp panel was not used

If your rig came with washer and dryer it would have had a 50 amp panel.

Main 30 amp 2 pole breaker, 1- 20 amp A/C breaker. 1 general circuit breaker, 1 GFI circuit breaker, 1 fridge breaker if electric, 1 water heater breaker if electric volt. 1 microwave if you have one. 1 washer, 1 dryer.(both 120 volts) All these other breakers being 15 amps.

That's at the very least 8 full sized slots filled with 1- 2 pole and 4 twin breakers. The 2 pole being a quad 4 handle 30/20 main? Am I close? That's why asking for a picture. one with the cover on will do. As long as I can see the breakers.

Thank you again.

Fans are 120 volts. Not a fuse problem. Only fuse involved with the A/C is 12 volt control circuit.

5 breakers are not enough to handle the load. Count the individual handles and tell us what sizes they are (30,20, 15) panel sounds way too small for a 5th wheel trailer.

[gcharles]

The breakers are as follows: 30 amp main breaker, 20 amp A/C breaker, two 15 amp breakers for camper's outlets, and a 15 amp microwave breaker.
The camper's additional 30 amp cord coming in as an aftermarket cord is wired into the camper's electrical panel, but doesn't have use of a breaker in the camper.
Everytime I trip off that side of the camper's breaker, it trips off at the panel box outside that feeds the camper.
The camper was manufactured with a 30 amp service and this electrical panel.
The original owner had an RV company put the second 30 amp cord in as an aftermarket cord...this camper has most of the available options from Coachmen including the washer/dryer hookup.
It makes sense that the owner knew this camper needed more power, hence the second 30 amp input.
Now that I have the paperwork for each of the systems and appliances for this camper, I'm going to scan them in and then post them on this forum in a separate thread.

[gcharles]

Well, success!!
After I went to AutoZone and bought the two 15 amp fuses (Bussman) and put them in, now my A/C works!
I learned a lot in the course of the 'drama', and thank you for all your help.
I finally got to the bottom of it and I'm thankful to be able to move onto other camper projects, like fixing my screen door and hinge's alignment, changing my right-hand step rail so I can open my door and leave it open in the warm weather before I have to put the A/C on, and pump water through a 150 foot hose from my spring to my water inlet so I can fill my 40 gallon water holding tank. I haven't been able to use my faucets and shower yet...

[rockfordroo]

Congratulations!!

Thanks for coming back and letting us know you got it figured out.
