Converter repair or replace? 2012 Access Chalet 31C

[Chief deputy]

Hello all,

We just returned from a week long trip. While we were out I noticed our refrigerator would only run on LP and not electric. We got home yesterday and today I started troubleshooting. I unplugged the fridge and tested the outlet and discovered no power to it. I went in and checked the breaker to discover it was tripped. I reset it and when I did it arched and sparked so I flipped it back off. I’ll attempt to post a photo or two. There is a circuit board under the breakers and fuses. I believe this is part of the power converter. Not sure if I can replace the circuit board or the whole converter. Anyone know if this is the power converter? If so, what’s your opinion? If not, what is it and what do I need to do?
Thanks in advance for your help!
