Whirlpool Fridge Making Strange Noise

basically the sound is sporadic but when it starts it last for about a few hours off and on. Best I can Describe it is like a pump sucking water but it's sucking when the water level is low. It seems to be to the right hand side of the fridge ( water filter side) but I can't tell if it's top or bottom. Not sure where to start looking. I do have water pooling and frozen on top if the freezer but not inside . Also noticed that the blower in the middle drawer has a small section that's iced over. Any suggestions, I can send pictures or video.

Clogged defrost drain, or incomplete defrost. Noise is likely fan hitting frost/ice. 
 

It needs disassembled and tested.

Yeah, If there are no obvious leaks from the filter area, then I'd also suspect a drain issue. Check the condensate drains in both sections down to the condenser pan. If it's partially clogged, it can gurgle and make a surge sound. That would also explain the water/ice in the bottom as the condensate will back up and can freeze in the drain tube(s) so you'll have to clear the initial clog as well as clear any ice from the drains.

I attached a video of the sound. How best to unclog/ unfreeze the ice? Do I just shut my fridge off for a few hours?

Ok, that doesn't sound like a drain gurgle. As was said above, almost sounds like the fan blade hitting ice build up. Hard to tell though.

As far as checking and clearing the drains, shutting the unit off for a while won't necessarily do much because if it is clogged you still have to unclog it as well as get rid of any ice build up in the drain. You can get behind the unit and take the rear cover off the bottom where the compressor is and find the drain tube where it drips into the condensate pan. Some drain tubes are easy to get to, some not so much, but you can also use a piece of hose or something to hook onto the drain and blow through it to clear any clogs of crud. Now, if it is frozen up inside then that's a little more involved as you usually have to remove the rear panels from inside the unit and find the drain hole below the evaporator coil and run hot water or something down through it to melt the ice. Once the ice is gone you can blow through with a piece of hose and make sure it's clear. It's not uncommon for drains to get clogged but sometimes you have to do a bit of work to get them cleared, especially if it is iced up.

Checked my drain line today, looks like I have 2 lines. The pan was bone dry. I left the fridge unplugged for 4 hours and the block defrosted half but still nothing drained into the pan. The sound is still just as bad.

Try to attach a piece of hose solidly onto the drain stubs that are sticking through the bottom, and blow up through both the drains to clear the lines. Also, that black piece and that loopy white trap tube could be clogged as well. Remove those and blow through them as well to make sure they're clear. If the white and black tubes in your pics are clear, then the clog has to be above that somewhere in the drain line coming from the evap area. If you can't blow any air at all through the drain tubes coming down, then they're probably frozen over.  Ice can fill the drain tubes for a few inches deep so only being off for a few hours probably won't be enough for it to melt. If this is the case, you'll need to get into the evap areas and find the drains and introduce hot water into the drain lines to melt the ice. Once the ice is melted, then also blow through the drains to clear any gunk clogs. If you don't clear out the gunk then it'll just freeze up again.  So, in a nutshell, melt any ice in the drain lines and blow air through the lines. There's really no other effective way to do it.
