I haven't tried to cool with heat pump selected. Good idea. I'll need to remove the roof cover and clean fins (never had it off) anyway.
The touch pad offers 'heat pump'. Never occurred to me that it might not be installed.
Doesn't sound like the right model number. For your year trailer, it should be something like 630516.331 or another combination of the same number of digits, but will probably start with the first 3. (630515.321 is another example).
The data label will have a model number, product number and serial number on it. You might have to remove the shroud to see the label, which is usually on the street side of the A/C unit.
