Hello! We have recently purchased a Moho privately and unfortunately didn’t check the fridge was working…it wasn’t and unfortunately had to replace it with a Thetford 3 way. We are currently camping and the fridge was fine for a couple of days but now we are getting a smell of gas in the van. My husband has been advised to silicone around it but is struggling to remove the top panel to silicone behind. Does anyone know if this panel comes off? Also the top external vent is hot now we have switched over to electric. Is that normal does anyone know? Thank you. Any advice would be appreciated.
