Everything in the refridgerator is frozen,

There are plenty of reasons this could happen like the following: PROBLEM POSSIBLE CAUSE Loud operating sound level • See "Sound Information" section for explanation of normal operating sounds Freezer too warm. Compressor not operating • Freezer temperature set too warm • Defective compressor • Defective overload or relay Refrigerator too cold • Refrigerator temperature set too cold • Chefs Pantry control set too cold or misaligned allowing freezer air to escape into refrigerator section • Freezer temperature set too cold • Restricted condenser air • Refrigerant shortage or restriction • Refrigerant overcharge Freezer too warm. Compressor cuts off on overload • Heavy usage • High ambient • Restricted condenser air • Defective condenser fan motor • Loose or missing condenser fan blade • Improper voltage • Defective relay or overload • Compressor motor winding • Non-condensibles in system • Refrigerant overcharge Freezer too warm. Compressor operating • Freezer temperature set too warm • Restricted condenser air • Defective condenser fan motor • Opened door • Heavy usage • Defective freezer fan motor • Opened defrost thermostat • Opened defrost heater • Loose or missing freezer or condenser fan blade • Heavily frosted evaporator • Refrigerant shortage or restriction • Inefficient compressor Refrigerator too warm • Refrigerator temperature set too warm • Freezer temperature set too warm • Return air or air supply duct blocked • Chefs Pantry control set too warm or air supply tube blocked • Heavy usage • High ambient Problem Possible Cause Freezer too cold • Freezer temperature set too cold Long off cyde • Low ambient • Freezer temperature set too warm Short off cycle • Heavy usage • High ambient • Freezer temperature set too cold • Light constantly on • Poor door gasket seal Long or continuous run cyde • Heavy usage • High ambient • Inadequate condenser air flow • Freezer temperature set too cold • Loss or restricted refrigerant Short run cycle • Light usage • Low ambient • Freezer temperature set too warm Exterior cabinet condensation • High humidity. Design accepts beads of water on cabinet exterior after 4 hours with 0° to 2°F (-18° to -17°C) freezer food temperature and 38° to 40°F (3° to 4°C) refrigerator food temperature in 84% R.H. conditions. See "Typical Sweat Pattern" section under above conditions. • Freezer temperature set too cold • Poor door gasket seal • Insulation void

probably a thermostat for the freezer
have a fridge technician check it out

Check your coils to see if they are dirty. If they are underneath the refrigerator you can vacuum them as best you can, or if you have access to an air compressor, you could try blowing them clean. Too much dirt on the coils can make you unit work harder and cause warmer temps. What is your temperature in the freezer section. You only need 32 degrees to freeze things, but it should be down below 10 degrees for everything else to work right. Hope this helps!

Your freezer should be in the range of -2 degrees to +2 degrees. Your fresh food section should be in the range of 35-40 degrees.

You only have one cooling source and that is the evaporator coil in your freezer. The freezer will attempt to satisfy the freezer temperature setting first. Having met that it will open the air damper to your fresh food section. Such a high freezer temperature will cause freezer burn on your food. It is also a waste of electricity, where the compressor is always running to meet the high demand

On the fresh food side you have it set at the proper temperature. Most thermostats have a scale from 1 to 7 or 9. If you set the thermostat at 5 this equates to about 37 degrees. Thermostat do lose sensitivity after a while and need to be replaces. The switch inside the thermostat wears out and the sensing bulb sometimes loses the fluid inside the sensor and the thermostat stops controlling temperature. So sounds like you have it set properly.

It could be freezing up in the freezer part of the fridge, or you may need to add coolant or freeon.

Get/buy an external thermometer for both the refer and freezer to double check your settings. Refer around 38 to 40 F and freezer usually around 0F

HIGH-TEMP ALARM SWITCH (SOME MODELS)
An audible alarm will sound if the freezer temperature reaches
unsafe levels. The alarm operates on household electricity.If
the power fails, the alarm will not perform.
An ON/OFF switch allows the high temperature alarm to be
deactivated if desired. NOTE: You must open the freezer door to
view the alarm switch. The freezer is shipped with the switch in
the OFF position.After the freezer has run longenough to
lower the temperature, you may set the switch to the ON
position.
• To activate the alarm, set the switch to the ON position.
• To deactivate the alarm, set the switch to the OFF position

i got this from the freezer manual from Kenmore hope this was helpful

Yes, probably frozen. Open the door, minimize the freezer setting in the refridgerator section, and try out the dispenser every once in a while until you get water to flow. Might take a couple of hours so make sure you have a backup freezer or a big cooler for your food.

Have person who changed out you controlboard come back and recheck connections and controlboard itself.
