Frequently-replaced parts in United upright freezers

• Door switch. The door switch turns the freezer light on and off and monitors door position. Replace the door switch if it doesn't work.
• Door gasket. The door gasket is a flexible seal that attaches to the outer edge of the freezer door to form an air tight seal around the door opening. The door gasket prevents warm, moist air from leaking into the freezer compartment when the door is shut.
• Control panel. The control panel houses the selection buttons and the display for the freezer. The control panel connects to the electronic control board through a wire cable that communicates button presses and display functions.
• Electronic control board. The freezer electronic control board controls the major electro-mechanical components in the freezer. When the electronic control board senses the compressor needs to run to cool the freezer, it sends voltage to the compressor and fans. It then receives input from temperature sensors to monitor the temperatures inside the freezer. With this information, the electronic control board controls the defrost cycle.

How to deal with a noisy United upright 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 gasket can cause excessive frost to build up inside the cabinet and on the evaporator. Replace the door 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.
