Cedar Creek AC units

[spawnman]

Quick question on our Dometic AC units. There is cold air coming into the trailer, it's not super hot outside, maybe upper 80's to mid 90's in the sun. The bathroom is nice and cold, the living area which only has the ducted system is not as cold as it has been before. Went on the roof this morning and couldn't seem to find anything to clean like a filter or anything.

Is there any kind of maintenance I can do on this? It seems to be running just not like it used to. (But then neIther am I!)

Thanks Greg

Get the model number and year of your AC. Then go to YouTube and do a search; i.e., filters, maintenance, not cooling COLD.

I had issues on a new 2015 model. I dropped the inside cover, got the numbers and called Dometic's help line. Unfortunately or fortunately, ( under warranty ) my unit was replaced. "Unfortunately", because they tore my brand new RV roof and full roof ( under warranty ) was installed.

Go back on the search app of this forum and search as well.

The Dometic's have mostly sealed units. Might just be bad.

Good luck!

The only filters I'm aware of are the return air filters in the ceiling...

I have a Prime Time Sanibel and it has the same type AC unit arrangement. The system is completely deducted. There is a air return on the ceiling that looks like a rectangular vent there is a air filter behind both of them. Clean and or replace the filter and see if it works any better. I change the filters each year.

Not exactly pertaining to your question, but several if us have replaced the non-closable vents with louvered vents in the bathroom where it was getting extremely cold.

As for the filter in your unit, it's behind the return grill in the ceiling.

I clean the ceiling return-air vents at least every 60 days. (Don't know where all the dust comes from with windows closed most of the time.) Get a digital thermometer and check at the return then check at the nearest outgoing vent. Should be a 15° difference. Lower level with higher ceiling and larger room is always warmer than upper. I have to keep reminding my wife that we're trying to cool a tin box sitting in the hot sun.
