Coil in freezer continues to freeze up. Then we have to defrost it again. Frig doesn't stay cold then freezer food doesn't stay frozen

You will need to remove the food and shelves from your freezer and then the back panel. Look for ice buildup on the coils and around the cold air tubes that allows cold air to enter your refrigerator. If you do have frost then you should unplug your refrigerator and defrost your freezer. You can use a hair dryer to hurry the process along, but be ready with a large sponge and bucket to deal with the water. The defrost sytem is usually made of three basic components: The defrost heater, the thermostat and the timer. You can check the heater and thermostat with an ohm meter - if you have continuity - less than infinity on your meter then they are normally good. If not replace which ever one didn't have continuity. If both are good then it is the timer and you will need to order one and replace it. You can do this by going to www.searspartsdirect.com and plug in your refrigerator model number in and pull up the diagram for you refrigerator. Those three parts will be in the freezer compartment - it will also give you an idea of what they look like if you are having a problem in identifying them.

Now for the good news. Your refrigerator will work without them for a week or so now that you have defrosted your freezer! So you can plug it back in and let it get cold and just wait for your delivery. NOTE: Suggest you take a digital photo of how it looks so if you can't remember later, you have something to refer to.
