Air conditioner freezing up question
My trailer has an airxcel 48000 series roof top unit. My question is have any of you, who have this unit, had any problems with the evaporator icing up? I did not need to use the unit on our first tri...

Though I do not have that specific unit ANY AIR CONDITIOENR can Ice up if it is not properly maintained.. Some of the more common causes.
In high humidity if you run the fan on LOW or AUTO it is poissible for ice to build up during the "Down time" and not melt.
Dirty air filters can reduce air flow which can cause several issues, of which Icing is one (Niagra falls effect is another)
If the RV is not properly leveled it may cause some ice to build due to the water level in the drip tray being too deep.
If the condenser coils are clogged, the fan has to work harder and thus slows down, since the fan motor also runs the blower this reduces air flow. NOTE this will also trip breakers as the blower and compressor suck more current.
And if it is low on refrigerant it can ice up This one may (or not) be fixable.
