Hi all. Have a Dometic 2200 roof top air con on our 17-56-2. Has been going ok and then today will start for about a second and then start flashing a red light? Book says this is a malfunctioning of the E1 temperature probe (internal) but gives no indication of how to fix? Any ide? In lovely Exmouth for another couple of days and would love to be able to use the aircon again. Cheers in advance Ashley.
