Main A/C

Today at noon I realized that my main A/C was just humming and not blowing anything. I checked the thermostat and it was set to "low on" instead of "low auto" where I usually keep it. Probably the doings of my 3yo. So I switch it back to "low auto" and still just a hum. So I turned it off for a few minutes and even reset the breakers and still just a hum. But if I switch it to "auto high" then it works. Any ideas?

Also, the fan setting alone works on low and high.

Check the voltage coming into the TT. Most things in the TT can work on a varying amount of voltage but not the AC.

Not sure what is wrong with your AC but checking the voltage coming in is a good start.

Low voltage coming into the RV plus too much voltage drop caused by the compressor. A few drops of oil on the blower shaft may help, mine tends to stick if the A/C hasn't been run in a few months, so rotating it by hand and a few drops of oil and it is good for another summer season.

X3 on the low voltage. Been there. I keep a voltage monitor onboard. The shop where I bought my first trailer strongly recommended it after we had the A/C in for service subsequent to a series of brown-outs we had a local campground.

Apparently the new A/C units have built in protection now for power drops, but never investigated if the compressor can still be damaged from low voltage.

Our trailer is wired for second A/C, so we're running a 50 amp circuit and it appears that we have less issues running 50 vs. 30 at the mom and pop campgrounds.

While I've seen different numbers posted to various rv sites, I usually kill the A/C if I drop below 108v.

Great investment. Also monitor for other issues such as open ground, open neutral, and polarity issues. You can get it here at Amazon.
