I made an appointment for a service person to look at the freezer portion of my refrigerator. They can't come until Friday afternoon.

It seems that ice from the ice maker is clumping up in the bin. I also noticed that frost is forming on the lower portion of the inside door. And then, I think it's melting, causing some water to first pool on top of the fridge door, and some then drips to the floor.

For now a towel will mop up the water. Luckily it isn't a huge amount. If it gets worse, I may need to call another company. I used this company last year for my gas stove and they did a great job.

I've done quite a bit of online looking and my guess is that it is the defrost timer that needs to be replaced. I think it is defrosting too frequently for the fan to keep up. It could be a bad seal on the door, too, but it looks okay to me. I'll let you know how it works out.
