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.
