The refrigerator portion does not cool properly. I'ts been really really hot and I noticed the freezer was set on MAX. Even though the unit thermostat works properly and is set on COLDEST. Would the fact that the damper is almost shut be the culprit? I tested the thermostat and defrost timer and both checked out OK. Thanks!
ANSWER Hello Bruce,
The fact that the freezer is on max is why the fresh food section is warm. You see, the max setting on the freezer prevents air to flow as needed into the fresh food section. Think of it this way, the fresh food control is the electrical control which turns the compressor and fans on and off as needed. The freezer control is an air flow adjustment which controls how much cold from the freezer section is allowed to pass into the fresh food section.
Another factor to consider is that the units are designed to operate at maximum efficiency when in room temperature,(70°F to 80°F). You see, refrigeration doesn't make cold. It removes heat. The heat it removes is carried to the hot coils outside of the unit to be dissipated back into the room. When the hot coils are in an environment that is as hot or hotter than the coils, the unit cannot dissipate the heat, so the inside of the unit cannot get any cooler. This causes long run times and will prevent the interior from ever satisfying the thermostat.
