Out of Level and overheating will do just 1 thing---DESTROY(block) the cooling unit. There is NO way for a fire to happen. Both Dometic and Norcold have installed overheat temp disc's for the past 23 years. So, if it overheats, the unit trips the disc and shuts off all power to the refer. BUT, the damage to the cooling unit has already happened. If I had a rental or was dumb enough to let friends and family use my RV, I would install the ARP device . This keeps anybody from operating the refer when it starts to overheat. Doug
