How to deal with a noisy Whirlpool freestanding freezer

Excessive frost on the evaporator can interfere with the rotating evaporator fan blade, causing a loud buzzing noise inside the freezer compartment. If you hear buzzing and the noise gets louder when you open the freezer door (indicating the noise is coming from inside the cabinet), check for excessive frost inside the freezer. If you find excessive frost inside the freezer, find and repair the cause to eliminate the buzzing noise.

A leaky door or lid gasket can cause excessive frost to build up inside the cabinet and on the evaporator. Replace the door or lid gasket if damaged. Manually defrost the freezer by safely storing food and unplugging the refrigerator. Prop the freezer door open and allow room-temperature air to circulate through the freezer cabinet to defrost the evaporator. After 24 hours, close the freezer door and plug the freezer back in to restore cooling. If the noise resumes, then you may need to replace the evaporator fan because its blade is damaged.

What to do when your Whirlpool freestanding freezer isn't cooling properly

If you hear the compressor running but the freezer doesn't cool, a sealed system problem such as a refrigerant leak or a failed compressor pump may be causing the problem. A service technician will need to fix a sealed system failure because the repair involves the recovery and recharge of the refrigerant.

If the freezer cools but doesn't cool down to 0 degrees, a failed thermistor may be inaccurately detecting freezer temperature or the electronic control board in the freezer may be inaccurately detecting the thermistor signal. Using the freezer's tech sheet as a guide, unplug the freezer and check the resistance of the thermistor using a multimeter. Replace the thermistor if its resistance differs from its expected resistance. If thermistor resistance is okay, check the resistance of the thermistor circuit from the wires that connect the thermistor circuit to the electronic control board. If you measure the same resistance through the wires that connect to the control board as you measured directly at the thermistor, then you'll need to replace the electronic control board because it isn't accurately detecting the thermistor signal. If the thermistor circuit resistance differs from the thermistor resistance, then a wiring failure in the thermistor circuit is interfering with the thermistor signal going to the control board. Find and repair the bad wiring. If your freezer uses a dial control, the cold control thermostat may not be sensing and controlling freezer temperature properly.
