Hi, we have a 2003 Fleetwood Heritage. It’s stored at home on a flat drive and we tend to keep it plugged in to our mains electricity about a week before we go away. Last week the fridge/freezer just stopped working. I thought it might be the main element but it’s not working on gas or DC either? There is definitely power to it, the fridge light comes on when you open the door etc, the gas lights without any issues it just won’t get cold. ☹️ It’s a Dometic RM6501. Does anyone have any ideas what I can try? I really don’t want to replace it as they cost a fortune! Any advice would be very much appreciated. Thanks
