why is water pooling up in bottom of fridge... ice maker is not working, so why & what is leaking?

Noticed small amt of water on floor a few days ago. Thought it was from a dropped ice cube (made the old way with ice trays). Mopped it up, later found water on floor again. Yesterday it was a pool nearly 2 ft. across. Have taken everything out looking for source. Water is slow dripping from the left side of the back wall and from around the bottom of the control panel in the middle of the back wall. There is nothing leaking from the freezer (nothing visible & everything in the freezer is frozen rock hard.

Boyfriend says his Dads fridge can't be leaking at all because there is no water running to the fridge at all. So where is this coming from? It is obvious it is leaking water...but what could be the source?

Also the electric bill here has jumped way too high for what is running in this house. Example: Boy friend has 4 PCs, two fridges with freezers and one freezer. His house is 2 1/2 times bigger than this house. He has more lights, a dishwasher, which isn't at his Dads, boyfriend has high tech hot water heater, washer and dryer. Recent light bill at boy friends $230 last month. So is ours.

We have one fridge...freezer on top, air conditioner, oil heat, gas hot water heater, oxygen machine, 3 box fans to circulate air, washer dryer, stove, microwave. Fridge, stove,washer, dryer are all at least 15 years old or older. Our bill is $ 230 also.

I believe the meter here is faulty, it is 9 or 10 years old. I called the electric co and they told me that the meter IF faulty will Fault to Our Good.... don't have to be an electrician to know that is B S. They told me I had to cut off everything and let the electricity drain out of the house.LOL more

B S. They might as well told me there is no such thing as tires on an auto or a horn or seat belts or a steering wheel. That is B S too. But they tried to sell me that crap and I know better. Was not born under a rock and my parents weren't monkeys either. Dad had a high I Q and I do to. Just sit on mine and even put in mistakes so I won't make people feel bad.

But this makes no sense unless boyfriend hooked up the water (forgetting the ice maker won't work). And failed to tell me.. I think the age (near 26 to 30 years old is more the culprit. But on the other hand why hasn't it leaked until now?
