Air conditioning question

[slaslo]

Hello all,
I have a question about the air conditioner for a 2014 gray wolf 26DBH. Is it normal for the ac to run/shut off and 30-45 secs. later cycle back on and run for three minutes and shut off again? Outside temp was low to mid 80's with high humidity. Inside thermostat was set to 74degrees.
Any and help is greatly appreciated
Cheers..

I'm not sure if it's "normal" or not, but considering a thermostat is designed to hold a constant temperatuure, and given the smaller space it's cooking I could see it happening.

Just out of curiosity though - is there a vent near the thermostat that could be blowing cold air on it? I imagine there's a likelyhood of the AC kicking on, blowing cold air on the thermostat making it "think" the whole camper is 74 - once it kicks off it quickly registers it's still too warm in the camper and turns the AC back on, thus repeating the cycle.

Do a search for the word 'cycling' and see what others have done/recommended.

No that isn't normal, that is short cycling the compressor in the A/C unit which isn't good on any A/C unit.

Thanks everyone.. I think there may be a vent pointed at the thermostat..
Awesome input.. Thanks

Cheers

you could be low on refrigerant and the low pressure switch is kicking the compressor off... or the condenser fan isn't coming on... or air blockage to the condenser and the high pressure switch is kicking the compressor off.

Update... The thermostat fan was on Hi.. Switched to auto as well as turner the vent away from stat... Wala..
Seem to be working ok now.. Once we get back into the cooling season I will have a better idea.
Thanks again for the help😄

Press mode till fan shows, press +\ - for high/low/auto.

If this is your therm.

I don't know about your manual but the answer is at least implied in post #7 and matches fact on my trailer. I don't know if yours is the same.

Use the mode button (or whatever it's called on your thermostat) to set the unit to Fan... not Cool or Heat. Then use + on the right to cycle through Hi, Lo, Auto.

If that doesn't work, your thermostat is not like mine.

Ford Idaho beat me to it!

It worked! Thanks so much!

So, is fan/auto still AC?

As long as you have the therm set to A/C.

Again press mode till the A/C is selected it should cool till the set temp is met or the A/C is maxed out.

As I understand it, the Fan modes Hi, Lo, Auto tell the fan how to act when the operating mode is set to Fan and/or Cool.

Edit:
Too late again! ... and not quite right. Fan on Fan mode has no need for Auto, just Hi and Lo.

Mine does the same thing, but not frequently. I finally figured out that, with the AC on and the fan set on "auto", the AC will fire up with the fan on high. As it gets closer to thermostat set point, it will shut down and come right back on with the fan on low speed. It will likewise shut down and restart if the fan is on low and it gets to far behind the set point it will go to high speed.
