We bought a used RV & the refrigerator never worked right. I called some repair guy who said 9 out of 10 it needs to be replaced. After several phone calls, I called Coastal RV & told me he can come for a quick look. He looked in the back of the fridge and everything was okay & told us to put a 2 x 4 to level the RV better & we waited several hours an yes it worked. Day 3 and it still works and we are going on a trip and feel confident it will work. The sweet part is he said its no big deal and wait to see if it will work. He didn't charge us. I will definitely trust Coastal. Thank you!!
