Defrost Adjustments - Freezer
Optimal defrost is accomplished when the defrost cycle ends immediately after all the ice has cleared from the finned coil surface
on the evaporator. Too long or too short of a defrost period may cause operational problems or waste electricity.
The defrost periods set at the factory are for "average" freezer use. Depending on the frequency of door openings and the ambient
climate, it may be necessary to make adjustments to the defrost cycle.
ICE DROPLETS FORMING ON THE CEILING is a sign that the system is remaining in defrost too long after the ice clears from the coil
fins. This can be corrected by turning the defrost duration screw towards the "shorter" position (fig. 5-1). If freezer still
remains in defrost too long, a defrost setting pin should be removed from the timer clock (fig. 5-2). Repeat if necessary.
ICE BUILD-UP ON BACK OF EVAPORATOR COIL is a sign that the defrost period is not long enough. Turn duration setting towards the
"longer" position (fig. 5-1). If build-up still occurs, a defrost setting should be added to the timer clock (fig 5-2).
