I bet the cooling fins are dripping water like it should into the tray but the drain or hose is blocked and not dripping out like it should.
Open the fridge door on outside, see that hose that comes off of fridge and goes thru the floor to drip the water outside like it should.
Look for debris in the bottom of the drip tray and roll up your sleeves.
