Frequently-replaced parts in Danby 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.
Troubleshooting your Danby upright freezer when interior lights don't work
If your interior lights don't turn on when you open the freezer door and you already replaced the light bulb, then the door switch may have failed. Unplug the freezer and test the door switch with a multimeter. Replace the door switch if it failed.
Some upright freezers use LED's to light the interior compartment. If an LED light board doesn't light up when activated, replace the light board.
Faulty lighting system wiring also prevents interior lights from working. Replace or repair any damaged wiring in the lighting system.
