All of a sudden my side by side freezer/fridge is not colling well. I cleaned dust from the rear where the condenser is. No difference in cooling from that. I ordered a condenser coil brush and will try cleaning those Saturday when it arrives. Here are the symptoms.

1. Freezer temp is 26 degrees F and Fridge is 48 degrees F.
2. Something keeps running but stops when ever I open either door.
3. There was a small puddle on freezer side. I now may see a spot or two on bottom rim of fridge side.
4. Adjusting temp settings seems to do nothing.

Please advise on what parts to check before I place an order.

Thanks!
