My daughter bought an old 1978 Flair. We have been fixing it up and it's look great. Sadly, while it was parked and plugged in, her roommate ran over the electrical cord with the lawnmower, chopping it up and requiring it be replaced. They replaced the cord and everything worked fine except the AC. The roof unit, which worked fine before the incident, now won't even turn on. I have checked the fuses that I can locate (the tube glass kind) and they seem to be intact. Can anyone give me any other advice on troubleshooting? Thanks so much!Here's a photo:http://i1244.photobucket.com/albums/gg569/LydiaS65/1840531955850175325-account_id1_zps9rpkvrhs.jpg

So we're talking the rooftop A/C unit that cools the house part of the coach (not the engine driven "dash air"), right?OK, does this A/C have a wall thermostat to control it, or only two knobs on the unit itself, at the ceiling?What's Make/Model of the A/C?Usually, everything 120 Volts AC, running off that cord that got cut, is protected by Circuit Breakers, not glass fuses. Newer coaches use plug-in automotive plastic fuses for the 12 Volts DC stuff like lights. Older ones used glass fuses, but again not for 120 VAC stuff. See if you can find your "Load Center" which may be Breakers and Fuses in two separate devices/locations, or combined. Post pictures!

It runs off 120v not 12vCheck the circuit breakers in the RV converter power centerMove them all the way off, then back onCheck the circuit breaker in your house that feeds the outlet they are plugged intoThe lights and water pump run on 12v and could be using battery power

Was the cord replaced with the same gauge wire? If the wire is too small there may not be enough current to start the compressor.

i'd check the continuity of all three wires from plug to outlet. did they splice the old cord back together or just replace it with a "correct" REPLACEMEnT?what was the configuration of 30 amp service cords back then?bumpy

also, I would take what is left of the original cord, splice the two ends back together ( assuming they are color coded, and see if it works. don't know what electrical damage would be done chopping up a cord) was the AC on/working at the time of impact? it all of the other 120 volt items still work, might have blown something in the aC.bumpy
