samsung rs21 wasm–rsh 1dth — rsa1wtmh

a couple of these came up with the same problem works for a few hours then dosent start unless switched back on, the defrost sensor in both fridge freezer has been changed,as it waits for temp to rise to 17 deg on the deforst cycle before switching back on,
heaters are also, only thing left to check is teh environmental stats on them all. just wondered if any one had come across this on a frequent basis, and does any on have a way of getting into samsung sit e to get the tech manuals. when i was with gbdar i used to get in,but i havent used my pass for a while so its locked me out.
