AC and Heat pump not working
I have only used my AC twice since I have owned my coach. I bought the coach brand new so it has no history. One trip I was on it was rather hot so I decided to run the AC. Right after I turned the unit on I smelled a burning smell while the unit seemed to struggle to run. I shut the system down and didn't try to run the AC again that trip. It was my last trip of the summer so didn't think much about the AC much after that trip. My next trip was during cold weather. I switched the thermo to heat pump and waited for the unit to run and start heating. The unit ran but no heat came out. I also have attempted to run the AC again. The unit did not produce any cold.
I have no idea what could have happened but fear the worst, an expensive repair. If anybody has experienced a similar situation a little guidance would be appreciated.
