Hi Everyone. Well, after 15 years the RV-Dreams Community Forum is coming to an end. Since it began in August 2005, we've had 58 Million page views, 124,000 posts, and we've spent about $15,000 to keep this valuable resource for RVers free and open. But since we are now off the road and have settled down for the next chapter of our lives, we are taking the Forum down effective June 30, 2021. It has been a tough decision, but it is now time.

We want to thank all of our members for their participation and input over the years, and we want to especially thank those that have acted as Moderators for us during our amazing journey living and traveling in our RV and growing the RV-Dreams Family. We will be forever proud to have been founders of this Forum and to have been supported by such a wonderful community. Thank you all!!

Where can I find the location of the filters for the air conditioner/heat pump?

I was reading the operating instructions manual for the Dometic thermostat in my 2018 Mobile Suites 36RSSB3. In the manual, under the "maintenance" section, it talks about replacing the "air conditioner/heat pump air filters."
Does anyone know where the filters are located in the Mobile Suite units?

Thanks, David.

I usually find information about products by doing a google search using the manufacturer and model number of the product. You will usually find listings for owner's manuals and service manuals. These are also available on the Dometic website in the custome support section

I can't speak to newer models, but our 2010 Mobile Suites has four intakes in the ceiling; two in the kitchen/dining room area and two in the bedroom.  Take those down and rinse out the foam pads that are placed on the intake grate and squeeze out the water and return back to the ceiling.

In addition to an annual rinsing/cleaning of the foam filters, I also get on top of the RV, remove the A/C unit covers, and using an air compressor, I blow out the cooling fins of the two units.  I blow on the fins from both sides until I don't see any more dust flying out.  Been doing that maintenance since we bought ours in 2010, and the A/C units are still working well.

(Well, unless the outside temps get up over 100 degrees.)  We have also changed out the original ceiling fan for a Hunter 5 blade 42" one, and we use two Hunter oscillating fans to circulate are in the living area and the bedroom.
