The condensor coils dissipate heat. If dust and debris accumulate around the coils, your freezer may not be able to cool properly, it may run continuously or it may stop completely as a result of an overheated compressor.
Before cleaning the condensor coils, unplug the freezer to avoid a shock hazard.
You should clean rear-mounted coils once a year. Unplug the freezer before cleaning. Freezers are heavy, never tip one forward or backward. When attempt to move a freezer without an assistant.
Vacuum or brush the coils. If coils have a filmy build-up, use warm soapy water to clean them. Take care not to spill or drip water onto the components of the freezer.
Floor Level Coils
You should clean floor level coils at least twice a year. Unplug the freezer before cleaning. Vacuum or brush the coils.
Remove the grill from the front of the freezer and use a vacuum with a wand attachment to remove any dust and debris. The grill should snap off and on. Pull firmly toward and possibly upward to remove the grill. If it does not come off with a modest effort, check for screws or retaining clips that may hold it in place.
