Both a/c's acting funny today

[cedar creekin]

I came home today to find my rear a/c humming, I had to kill the power at the breaker to shut the compressor down. I Jumped online and found it to be pretty common, so I ended up ordering a new control panel.
No big deal I have my front a/c to hold me over, or do I.... I went to turn it on and it's only working on low/med, No fan on the high setting ?

I cannot find any trouble shooting online for Dometic a/c's.
The front a/c is only three years old and rarely get used. Anyone have the high fan setting quit working?

Thank's,

Was the one froze up with ice?

You may also check your voltage coming into the coach. Make sure you have at least 110v(you may be ok slightly below that (108v?)).

Nope, no ice.

I've asked the campground twice to come check it and they haven't yet.
That was my first thought, but my compressor is working on the high setting, but no fan?
I've got a new control panel coming today for the rear a/c. Hope fully that will cure that a/c & I can focus on the front a/c

This would be a great time to buy a digital volt ohm meter and a progressive industries hardwired surge guard with remote display.
As you can see in pic "barely" it shows im using 10amps.
It also shows incoming voltage .

Thanks Turbs, that is an excellent idea. Takes all the guessing away.

And protects all your electronics!
Good investment.

Well after the campground never coming to check my voltage at the 50 amp box I bought myself a new multimeter and started checking myself.
Everything looks ok, 235v at the box, and 116v at the outlets inside the camper while one a/c is running. A touch low, but within spec.

My inverter/converter also checked out good.

Surprisingly after everything checked out my front a/c started acting normal again. (I'm thinking that I had a low voltage situation)

Either way I like your suggestion Turbs and I will def look into that meter.

I really am glad I installed the progressive industries surge guard with remote pendant.
I bought mine from a fellow frf user whom upgraded his camper and it was 50 amp so he no longer needed the 30 amp one that was a year old.
they come up once and a while on the classifieds but go quick.
its a very small investment considering what can be damaged from a voltage spike or low voltage.
OR even worse a power poll thats wired wrong.......

235V?!?!? We no likey the 240V!

You must have measured across the two hot leads to get the 235V, measure from each hot to the neutral to get your correct voltage being used by the camper, measure both sides to make sure they are near identical, if not there is something wrong with power pole and this will cause a "brown out" type situation.

I failed to mention that I did check each leg, & IIRC it was 116-117-ish, I forgot to post that.
I also checked both hot and seen the 235v.

sounds like you had an under power condition - luckily no significant damage

I have a device I plug into the power before I plug my camper in to make sure the power is good and wired correctly.
camping world sells them - here is a link Digital Line Monitor - TRC AECM20020-012 - Surge Protectors - Camping World

you will just need the plug conversions from 110 to 30 amp to work for your application or just run it inside in one of the outlets.

eventually I want to get a 30 amp hard wired surge protection with the remote display like this one - 30A Hardwire Surge Guard - TRC 34520-002 - Surge Protectors - Camping World

I have found that makariosrv.com has the best prices on the Progressive Industries EMS.

[TURBS]

I would go with the ProgressIve industries unit.
Lifetime warranty and made in the usa.
