Converter repair?

I replaced my converter two years ago. Now, it seems to be failing. I first noticed a problem with the A/c being unable to resume power after I replaced the start capacitor. I concentrated on the A/c and couldn't seem to find a problem. Then I noticed my battery was flat after I being hooked to shore power for two weeks. I drove home and the battery was dead the next day. I charged it normally with my own charger and the same thing happened again. I started checking things out and noticed the converter fan seemed to be clicking and unable to start.

What should my diagnostic steps be?

Some A/C thermostats are 12 VDC. That would be the only possible connection.

Please give us more information. We don't know if this is a motorhome (in which case the alternator should have charged batteries on your drive home) or a trailer.

Have you checked battery water level-- any exposed plates?

Have you fully charged the battery and had it load tested or checked the SG (Specific Gravity) of the cells. Often the symptoms of a bad battery and bad converter are hard to differentiate.

I am with Rich on this one, I would really be surprised if your Converter had anything to do with your A/C.

I am not an electrician either but I have been alive a really long time.

If I was an elect tech, I think I would tell you that your converter has nothing to do w/ your A/C
