first we found water on the floor several times. repair man insisted it was icemaker valve. after 4 trips and flooding frig i gave up on him. found drain was clogged and cleared it. but now it stopped getting cold. took off back panel evaporator was frozen over and a big chunk of ice had stopped fan. defrosted every thing. put back together. seemed to be working great for week or two, now same thing is happening. i can tell because it stops making ice. it appears to be frost at back behind icemaker that then turns to ice. is the problem the adaptive defrost control. where can i get a service manual. or is it worth it?
thanks
