The main entrance door usually has a lockable catch as magnetic catches are normally used for overhead lockers, cupboards and drink cabinets with swivel doors etc.
Are you sure it's a magnetic catch on the main entry door?
So this must be the external catch which used to be the old plastic type 'C' clip and gripper replaced with a magnetic type. I don't know what they look like in order to search for one, however, the Coachman is only 4 years old so wouldn't have thought it was that difficult to obtain one. Have you looked on Ebay and Amazon or even tried a Coachman dealer?
Kenmore Caravans in Yorkshire stock numerous parts for Coachman so try giving them a call as their customer service is excellent.
Kenmore is only a phone call away. I would be very surprised if they don't have what you are looking for as I have obtained obsolete Coachman parts in the past after searching everywhere else without success.

Mine went as well. Coachman dealers stock them !! They do break eventually but are easily obtainable. They come as a pair and cost about £15
Which comes to the conclusion that the OP hasn't really done any homework and tried searching themselves for a magnetic catch. I would have thought that a Coachman dealer would be the first port of call especially as the van is only 4 years old.
Adrian06, you'll find them online quite easily, eBay is awash with them and Kenmore have a FleaBay shop too.
I have a magnetic door catch on my Swift though too and its an awful idea, the slightest gust of breeze from the rear of the van is enough to release the grip and slam the door shut. I'll be fitting a conventional external door catch instead.
