If it's less than 1 year old ring Dometic and they will send you one, if it's 1 to 2 years old ring your dealer and they should get you one from Dometic.
If it's the same as ours whatever you do will be a waste of time as we have had 2 replacements in the 1st year. All I do now is leave out the fixing screw and if the metal bit comes out of the slot it's easier to put it back in.
