A/C Problems ????

[Rideandslide]

Hello All
Bought our new 2015 Grey Wolf 26RL in Nov. and was sure to get the 15K air conditioning unit, due do living in Southern Ga.
Well our first use of the air this week, blowing out ice cold air, so great,but as time went on it seemed to take a lone time to cool down the unit ( although the outside temp. was only in the high 70's ) it finally shut off ,and never came back on, as the temp inside went well above the thermo. setting. Got nice and cool that night, so just turned it off.

Got home and did the same test, same results, and saw a lot of condensate still dripping from the gutters well after the unit shut down ?, frooze up ??? Only in the 80's, brand new unit, under warrentee

Opinions please !!!!

Probably freezing up due to high humidity

Frost sensor could have Fallen off.

This.

hi rideandslide If the unit is freezing up the evaporator the most common causes is low air flow. Make sure dampers in the ceiling are open and air filter is clean. If this is not the problem It my have a low refrigerant charge which drops the evaporator refrigerant pressure/temperature to low and will cause the evaporator to freeze the water that is condensing on it.

Hope this helps Tim

What holds it on ? And as said, it's a brand new unit and it's going back to CW for another warentee problem already , so now they have another one. If it low refrigerant, should the unit be replaced ?, i understand you cannot service that !

Thanks All

A clip holds it on the fins.
If a/c is low on refrigerant they'll replace complete unit.

Did you try to use a/c with quick cool dump open?

If there is a plenum leak between the inflow and the outflow (in the space between the roof and the roof unit), the A/C can shut the compressor off early due to detecting icing; even if there is none.

Also if icing is confirmed to be your problem and you are operating in high humidity, setting your thermostat to 10 degrees below outside air temperature - not to exceed 90 degrees!) will result in cooling without icing up.

Setting the thermostat to 65 degrees in hot humid conditions will assure icing and poor cooling.

[TURBS]

Air flow as stated above is a big problem, on my unit if all vents do no remain open the a/c will frost up.
Which is why I asked about if it does the same thing with quick cool dump function open.

[Rideandslide]

Have not tried the quick cool, but never had any problems with my old unit, all inside vents open, filter clean ( brand new) will check frost sensor, but don't think i should have to play around to get a brand new unit to work as good as my old 2000 unit did. So far,love our Grey Wolf, i guess buying new has it's problems also . Just looking to see if i'm doing something wrong.

I have a 15K unit as well and it will REALLY get cold fast.
Comparing it in any way to an older 13.5K is not fair to either.

Thanks Herk !

But just comparing it to my old unit that worked great , so far new unit ???? Hope your correct in the end, that's why we insisted on the 15,000 unit

Hope you feel that way if you ever boondock with a 3K watt generator. The start up amps in that 15K will trip most 3K watt generators off line. Needed to heavily mod my Coleman Mach III 15K unit to run reliably with our 3K Yamaha.

Forget the 2K ones even with "mods"

Not into boondocking yet, just want this thing to work as purchased.

Agreed

How long is you RV? South GA is not as bad as SE Texas, Houston area, but not much better in the summer. My 38 foot fiver has two AC's 15,000 BTU in living area and a 13,500 BTU in the bedroom and in the heat and humidity of summer they both run most of the day just to keep it cool. Good Luck

[Rideandslide]

It's a Grey Wolf 26RL , specs. say it 30ft exterior lenght, but that's being very generous. The unit has not run long enough to tell,and it was barely in the 80's.

Took it into CW today for some other warrentee parts that had come in, so now they have the air conditioner proplem, will post their findings. Keeping my fingers crossed !!!!
