There is frost build-up behind the drawers in the freezer. It seems like it's effecting the performance...I believe the model is C16....30", and freezer on the bottom. Thanks

You have a defrost problem. If you do not plan to fix your self. You can take the back panel out from inside the freezer. Use a hair dryer and defrost then replace the panel. This will allow you unit to work normally for around 3 to 4 days. Anough time to get someone out to fix. If you plan to repair it your self. when you get it defrosted, ohm your heater that is found installed within your coils inside the freezer. If no continuity they are bad. Replace them. Also check you termination thermostat. They sometimes go bad. Most of the time it's the heaters. There is a slight chance that it could be the timer but with the new models that have the PC Board timers it's not likely.
Please rate solution if helpful.
