Garage AC on Valor 37v13

[JandKRip]

I have 3 ACs in my valor toy hauler, plugged into 50amp shore power but cannot get the garage AC to blow any cold air, blows air but not ac cold air, any suggestions? My dealer told me there is nothing wrong with the ac unit, but the air is just not cold like the other 2 are blowing out. We are in eastern washington, it's mid 90s, parked in shade but still cannot get garage to to a comfortable temperature.

Hi folks, I just copied and pasted a few things from one of my previous posts.
Is this a new problem? Was it working previously?
Was any recent work done that would affect the operation?
Do the thermostats light up and display a number?
Are they set to cool mode?
Is the set temperature below the room temp.?
Are the fans on?
Are the direct drop Luvers open?
Are the inlet air filters clean?
Have you checked the freeze sensor, for proper installation and placement?
Have you checked to see if they are icing up?
Have you checked the plenum divider behind the vent covers to ensure it is in place properly to divide inbound and out bound air?
Do you have a way to monitor you coach total amp draw? If compressors are running on all three units you should be in the area of +-30 amps on the system assuming nothing else on the 120v side is operating.
Have you checked for tree strike damage on the roof.
You may have already ruled some of this out, just trying to give you a few things to check.

Not a new problem, dealer told me it was working after first time, has never blown cold AC air
I have no way to check most of the stuff, no work has been done on it, fans are on and everything is open and clear, thermostat lights up and set temp is below room temp (it was in the mid 90s all weekend).
I have no condensation running from the unit when I check it, nothing flows into gutter like the other 2 units.
I have a warranty so looks like it might be faulty unit which ill have replaced now, just hoping to see if anyone had a solution I could try.

One possibility is insufficient refrigerant, which often results in warm air blowing out even after running for an extended period. This requires a professional recharge. If you're experiencing this issue, consider contacting a reliable HVAC lead generator like Aroundwire to connect with qualified technicians in your area.

Another potential cause is a clogged air filter, which can lead to reduced airflow, warm air, or strange noises. Inspecting and cleaning or replacing the air filter can resolve this issue.

Dirty condenser coils can also reduce cooling efficiency and cause warm air. Cleaning them with a coil cleaning solution and water can improve airflow and heat dissipation.

Blocked airflow around the AC unit can also be a culprit. Ensure there are no obstructions hindering airflow as it's crucial for cooling.

Thermostat issues might be causing inaccurate temperature readings or inconsistent cooling. Check the thermostat settings and calibration to ensure it's functioning correctly.

Can't check refrigerant; was told it is a completely enclosed unit.
Air filter clogged, is that inside or on top of the RV? Not too familiar with the AC units in the trailer.

Hello, your filters would be on the inside of your rig. They are contained within the cover of the a/c unit. You should see some tabs on the inlet grate. You unsnap the inlet grate and then slide the filter out of the housing.
