Please confirm the model number and what typ of controls you have.

[COLOR="Blue"]We replaced the overload switch.[/COLOR]
Which switch, the overload on the compressor or the defrost thermostat etc.?

Need more info as to what are the symptoms.
Is the compressor cycling?
Are there any strange noises?
You say it is too warm but what is too warm ? The freezer and/or the fresh food section?
Can you check with a thermometer, the temperature in the freezer and fresh food sections?
Freezer should be 0 to 5 degrees F, fresh food close to 40 degrees F.
Is the evaporator fan running?
Is the condenser/compressor fan running?
