Hi we have a Truma SE Motormover which was already fitted on the van when we purchased it. Other then an initial try to see if working when delivered as on a seasonal pitch we have not used and unfortunately we had left the batteries in the remote compartment which has now caused corrosion. Does any one know if the remote can be repaired or if we have to order a replacement handset how do you pair up with the mover on van. Any advice would be welcome! Thanks Annie

All the above , plus once fully cleaned spray all the electronics, pcb and battery terminals with Electrical Contact Spray.
Let it thoroughly dry, even leaving it in the airing cupboard overnight!

Please don't use emery cloth/paper/board , it will remove the electroplating on the battery contacts and the underlying base metal will rust again and you will be back to square one. If you do accidentally remove the electroplating a 'nickel' pen can can apply a film of nickel to the contact surfaces available from cpc farnell - part number SA 02343 , several coats are required.
I'd go with the repair guy Jcloughie posted about , also A & R electronics developments are pretty good and will probably replace the contacts with new.( I also keep a stock of battery contacts extracted from various electronic battery powered modules over the years for just such an eventuality).

We don’t know how bad the corrosion is .Leaking dry cell batteries give off a very corrosive alkaline residue , potassium hydroxide. I suspect any “plating” has been compromised.
So Annie needs to make the best of a bad job. Removal and cleaning up of the corrosion is very important.
Maybe the damage is already done and Mr Plodd’s suggestion will at least salvage the situation in part?
If it was mine I’d clean up and use the contact spray which as you know etches the surface. If the contacts thereafter are carefully cleaned regularly they should last a long time.
My own remote has suffered the same over the years and at 17 they are still going!

Thank you! Annie
Try A&R Electronics for repair or you may be able to find a used one on EBay and then pair it to your control box If you do buy second hand make sure you get the correct one as there are two types. One for manual operation and other for automatic has they have different buttons, Link here. https://www.arelectronics.co.uk/
Thank you ! Annie

Annie, a picture speaks volumes.
Thankyou I’ll try and work out how l add one to the post Annie

Order a fine brass brush from Amazon etc, they type used for suede shoes, give it all a brush and a dab of contact grease such as contralube.

Only attempt this if you are confident,

The white residue from the battery can be cleaned of using white vinegar I recommend using kitchen gloves and avoid breathing any of the fumes that might arise. This will froth up when it contacts the deposits and it may need some help from a small paint brush to help remove more stubborn deposits.
Provided all the copper tracks are intact on the pcb, there is a fair chance this will restore the function of the circuit, but its possible the electroplated nickel silver coloured plating on the battery contacts and springs may be lost. I have used solder tinning to replace some with success.

The circuit will need to be thoroughly washed off afterwards, and dried thoroughly. I find if you can set your oven to about 50 C, that will dry most circuit boards in about 30 mins. I have also used the dehydration cycle in my air fryer set to 50C Alternatively as Dusty has suggested leaving the PCB in the airing cupboard over night will also probably dry it of adequately.

On sensitive circuits I will usually add a sprayed conformal coating to protect the PCB but not on the battery contacts.

Not the best method, but in the past I have simply used an emery board to clean the contacts and it has always worked for me.

Thre batteries will be connected in series ie
Batt1+ to electronic top left contact
Batt1- to Batt2+ (two spring contacts in bottom left)
Batt2- to Batt3+ (two badly corrided contacts top right)
Batt3- to electronic bottom right.
The two contacts supplying electronics look good so remote electronics should've avoided any corrision damage.

Corrided contacts connecting batteries are made up of single piece of stiff wire with coils on each end and is just clipped into plastic. Buy a x3 AA battery holder and remove equivalent coils from that and press fit into remote.
See picture in link.

If they aren't drop in replace you may need to bend wire to suit.

I would look at using These just solder a pair together for the pairs and replace the main terminals as well.
Only downside you need someone who can solder
Or These
