** You said that yon never heard of the drip tray **
No. I said I never heard of
water coming from beneath that tray. Beneath that tray should usually be the door's insulation (which on modern refrigerators is usually foamed in place - "FIP" for short).
You might want to consider having a Frigidaire *factory authorized* service depot look into the cause for you. I can't think of an explanation besides
maybe poorly foamed in door insulation, possibly allowing condensation to form.
