We have a Kelvinator Impression series fridge, rear inside wall bulged and pushed shelves out opening door, switched off for awhile, shelves fit back in and door closes.

There is still a bludge in the back wall and the cavity between the internal and external rear walls seem to be full of water, (I thought water may have been a build up of condensation, frozen and bulged the internal wall). Fridge appears to be working ok, I pulled the evaporator tray off the top of the compressor, drain seems to be clear, there is another plastic gland 100mm to the side of the drain pipe and above the evaporator tray which may be a valve (not sure if you can confirm), did try to push it up but it would not move ( may be stuck) thought of putting a small hole low through the inside wall to drain water out, not sure if this is a good idea and it may not fix any underlying problem causing the collection of water between the walls. Any ideas would be appreciated. Regards Wayne
