A/C Troubleshooting

[AngusForsyth]

79 Sovereign, Canadian version (does that make a difference?)

Plugged into shore power last night, with the aircon running on low. Banged to a noisy halt, and now no univolt buzz, or A/C red indicator light on the status panel. 12 volt lights work, though.
I've got good shore power to the plug end of the shore power cable. Where to test next?
Does the SP power cable go directly to the AC panel in my trailer, or is there a connector somewhere?
After that, I'd assume that the A/C breaker panel is next - make sure the power goes that far, and that the breakers are working. (they still have a good snap to them? - and, yes, I have cycled the breakers back to 'on'!)
Anywhere further I should look, please?

Thanks!

Well, it appears that I've been running my air con on 15 amps, not 30, and so I've fried the insulation on the main power feed into the AC power panel. D'oh!
Now I just need to feed a little (6" or so) slack through, strip the new insulation away, reconnect, and I'm off to the races, minus aircon...

Huh, the lower feed should have tripped a breaker? Might want to check those out as well. But then I am not familiar with the wiring of older AS's. Good luck

Common mistake, live and learn. Good luck, hope your air isn't damaged.

The AC may have gone off on an internal thermal overload in which case it may have saved itself.

No worries, after I've fixed it, I'll plug it back in again, and see if it works any better next time 'round! Lol!

Well, I assume (I know...) that the breakers are fairly cheap, so while I'm in there, I'm going to replace all four of them.

[AngusForsyth]

Well, got 'er sorted. New breaker went in ok, and the wires all connected, so my ac power is back in business.
But, dammit, I think I've caught a renewal disease! Thinking to replace the univolt now, and perhaps the (rusty) dc power panel...

[drboyd]

Was it the GFCI breaker that went bad on you?

[J. Morgan]

If the wire insulation melted while running on 15 amp service something else is up.

The shore power breaker should have tripped before that happened (barring a loose connection).
