What to do if my Panasonic KM-DU73Y1 Freezer chamber is not cooling?
If your Panasonic Freezer chamber isn't cooling, first ensure the circuit breaker of the power source is active. Also, check if the voltage is too low; if so, call an electrician. Verify that power is supplied and the breaker isn't tripped. Avoid storing a large amount of items in the chamber all at once.
Why is my Panasonic KM-DU73Y1 cooling poorly?
Poor cooling in your Panasonic Freezer can stem from several factors. Check if the ambient temperature is too high, or if the inner door latch or outer door aren't completely closed. Frost or ice between the cabinet and the magnetic door gasket might also prevent a proper door seal. Make sure the air intake vent isn't blocked, and the condenser filter is clean. Also, verify that the set temperature in the controller is correctly set, the freezer isn't in direct sunlight or near a heat source, the rubber cap and insulation on the access port are correctly placed, and that you haven't put too many unfrozen items inside.
