Garage floor receptacle, and outside receptacle have no power.

[Phil870!]

Hello, hopefully some of you smarter then myself can help before I have to pull the underbelly, garage floor receptacle, as well as outside receptacle by the door do not work, checked fuses/breakers, checked receptacle’s themselves for being hooked up and in good shape, no power at wires.
Can’t find any gfi, and everything else in the trailer works.
Please help, what am I missing?

In our Road Warrior, close to the sink in the garage area is a GFCI. If not there look in the bathroom area in the garage if you have one.

Thank you for the reply, no back bathroom, and can not find a single gfci outlet anywhere, have one breaker labeled gfci, but it’s good.

A GFCI should be around a water source. So, start in the main bathroom, check around the kitchen area, outside compartments, any outside outlets.
If all of these are okay, you will need to find a junction box and start checking connections. A good place to look may be under a slide-out near the garage area.
Instead of dropping the coroplast bottom, get an inspection camera to help look for the wires and the trace the wires.
If you need to get into a junction box under the coroplast bottom, you can cut a 3-sided access panel, with the hinged side toward the front of the rig. Then when finished, tape it up with good tape.

A GFCI can be at a wall plug near a kitchen or bath. But instead the circuit could be protected by a GFCI breaker, which you indicate you have. The GFCI breaker could be on the circuit that controls the outlets that are dead. You said the GFCI breaker was good. Did you reset it by toggling it all the way off and back on again? Breakers can look like they are not tripped, even though they are. GFCI outlets and breakers can also go bad for no apparent reason. Once you toggle the breaker, if you still do not have power to the outlets, get a volt meter and measure the output poll of that GFCI breaker for 120 volts. As long as you are at the breaker box. Might as well check all the breakers for 120 volt output.

If that doesn't fix the problem, the next step would be checking all the connections in the junction boxes as david-steph2018 suggests.
