CamaroGirl Report post Posted February 13 Basement AC will only blow hot, was told the sensor for hot/cold setting is stuck and will the entire AC unit to be replaced as no one repair these units. So question is can it be fixed or just replace the unit? Share this post Link to post Share on other sites

So question is can it be fixed or just replace the unit? This goes back to how qualified and motivated to fix or sell new this person was. Is this unit a heat pump?

rayin Report post Posted February 14 (edited) That is simly untrue, there are many RV qualified technicians working on Coleman Mach/RVP basement units.This is perhaps the best shop for repairing ColemanMach basement units: https://shelburnerv.com/ they even have a utube video of them repairing one. First determine the model number of your unit. There is sticker on the left-end of the metal enclosure, you'll likely have to use a mirror to view it, as the space is very limited. Some units were air conditioner only, most are heat pumps.When they will not switch from cooling to heating or visa-versa, usually the thermostat is the problem. The thermostat testing procedure is in the unit service manual. This is the service manual for the most common model, 6535. When you unbolt the RR cover door and swing it up, fasten it to the rear ladder with a bungee cord. I'll stop here, I'm overloading you with information. The model# is the most important information needed right now. Edited February 14 by rayin Share this post Link to post Share on other sites
