I had this exact problem on mine. I took a panel off from back of inside freezer compartment, and there was a solid block of ice below coils. I didnt own a hairdryer, so used a turkey baster and hot water to melt it. Spray hot water in, wait 30 sec, suck it back out, get fresh hot water, repeat till you get drainage.
