1. Do you have a 30 amp RV plug at home for the RV?
2. House breaker, I assume your residential house breaker. WHAT AMP is it?
3. Does the fan come ON if you select fan only?
4. IF the fan comes ON, how long before the House breaker trips?
5. The Tstat will NOT be the problem
6. The Upper circuit board will NOT be the problem, unless you remove the cover and see obvious burned wires/circuits.
7. If the fan runs, does the compressor attempt to start or hums?
8. You need this tool to see what the amp reading is when the compressor tries to start.
