Roof-mounted RV air conditioners under normal conditions work well and are relatively maintenance free. Owners can get into trouble when older units start to lose their cool.
While it may be tempting to attempt to recharge the freon on your RV’s A/C when it’s blowing warm air, you’re far better off having a professional address the issue.
One cause of RV air conditioner failure is damage caused by attempting to run it when plugged into an outlet not rated for a minimum of 30 amps. That reducer adapter that allows you to plug into your house receptacle can’t handle the load. The air conditioner will be running in a low voltage condition and burnout is very likely to happen.
Beyond replacing a damaged plastic shroud that covers the A/C, there is very little an RV owner should be doing in the way of repairs to an RV air conditioner.
I’ve been involved in RVing for over 50 years — including camping, building, repairing, and even selling RVs and motorhomes. I’ve owned, used, and repaired almost every class and style of RV ever made. I do all of my own repair work. My other interests include cooking, living with an aging dog, and dealing with diabetic issues. If you can combine a grease monkey with a computer geek, throw in a touch of information nut and organization freak, combined with a little bit of storyteller… you’ve got a good idea of who I am. To date, I’ve shared my RV knowledge in over 300 articles here at The Fun Times Guide! Many of them have over 25K shares.
