Just moved in. Kitchen sink won't drain, but have snaked line and it is clear. Believe trap is airlocked. What to do?

Snake drain again, you didn't snake far enough. No such thing a trap being air locked.

I agree, no such thing as air locked trapped. Remove the trap and rod straight into the horizontal pipe coimng out of the wall. Use a small 1/4" snake because you are going to hit a 90 elbow about 5" inside.

I think this is your second post on the same subject. As stressed above: no such a thing as "air lock". As I told you in previous post, clean the drain with proper size snake and go as far as the length of the snake will go.

You should use 3/8" snake. If you use 1/4" you will clear the 90s - but it won't do that much. Find clean out on the opposite side of the sink or in the basement. If you don't have one - you should install one. The problem won't go away until the drain is either replaced or snaked properly.

I agree with all the experts above there is no such thing as air lock, snake it as they says see the image below, good luck.
