PROBLEM
Control panel will not light up.
Cabinet will not reach
desired temperature.
Display reads "dgF"
Display reads "dgC"
Activated red light above the defrost cycle button indicates DEFROST mode is in progress.
DEFROST CYCLE - "ON DEMAND" DEFROST
Press to ACTIVATE DEFROST at any time.
Press to CANCEL DEFROST in progress (Defrost Override).
It is possible that the unit will self-initiate a defrost if excessive ice is on coil. NOTE: If the coil is not defrosted,
temperatures will rise and reduced performance will be noticeable. If the unit is in a defrost cycle, it can be
cancelled by pushing the defrost button. This will force the unit out of the defrost cycle. The unit will await
30 to 60 seconds at the end of a defrost before the compressor and or the fans will return to normal operation,
achieving the best restart performance and cooling temperatures. In addition to a self-initiated defrost, the unit is
supplied with a forced "on demand" defrost cycle. It is located on the front control, and by depressing the switch,
the unit will be forced into a self-defrost (maximum of 20 minutes). During a defrost cycle, the indicator light will
illuminate above the switch and momentarily disable the compressor, the coil and the fans. Defrost feature allows
proper defrosting of the accumulated condensation and ice build-up on the coil. As with the self-initiated defrost,
if the unit is in a defrost cycle, it can be cancelled by pressing the defrost button. Wait approximately 60 seconds
for defrost to end. During the defrost cycle or the "Off Cycle" of the compressor, the evaporator coil will defrost.
The condensation from the evaporator coil flows from the top of the unit down a drain in the back to a condensate
pan. Vapor escapes through the back grill. The vapor can sometimes be visible and should be considered a
normal operating condition. Proper attention should be given to defrosting your unit. Every "event" or time the unit
is used with the door open, the coil will build-up ice, reducing the effectiveness of the overall operation of the unit.
If the temperature zone is too high and cabinet will not chill to desired temperature:
1) The evaporator coil needs defrosting. Press the "ON DEMAND DEFROST" button on the control panel.
Unit will defrost in approximately 20 minutes. Defrost indicator light will illuminate during defrost cycle.
The unit will automatically return to normal operation after a defrost cycle, having a transition time of 60 seconds.
Certain conditions may require 3 repeated sequential defrosts.
2) Dirt, lint, and/or dust are on the condenser (compressor) coil. To clean the condenser, first disconnect
electrical power to the cabinet and remove the screws on the front and/or rear louver assembly. Removed
louvered panel allowing full access to the front facing condenser. Vacuum any dirt, lint, and/or dust from the
finned condenser coil, the compressor and other cooling system parts. If significant dirt is clogging the condenser
fins, use brush or compressed air to blow this clear. NOTE: Care should be taken not to bend any of the
condenser fins, as this will reduce performance and compressor life. Replace louver assembly and
screws which hold it in place.
REMEDY
Cabinet not plugged into outlet or check fuse to power outlet.
Plug cabinet into properly grounded electrical outlet.
Press "ON" button.
Opening door unnecessarily. Keep door closed and latched shut after loading.
Set temperature to Display to °Celsius or °Fahrenheit Scale:
You may change the Digital thermometer scale to either °C
or °F as follows: While unit is OFF, press and hold the
"ON/OFF" button for five (5) seconds. The display will then
switch from "dgF" to "dgC" . Repeat to change scale again.
Temperature is set to °Fahrenheit Scale
