Is the condenser clean?
Viking's warranty does not cover cleaning of the condenser.
Condenser coils that are covered with dust and or pet hair restrict air flow, resulting in high head
pressures and reduction in efficiencies do to longer run times.
The condenser is located directly behind the front grille (Fig. 3). Use a soft brush and vacuum to
clean coil every 90 days.
Is the unit behind closed doors or is the air flow to and from the condenser
obstructed?
The unit must have free air flow to the front grille at all times to operate properly. Restricting the air
flow results in high-head pressures and reduction in efficiencies due to longer run times.
What is the controller set point? Has an adjustment been made?
Pressing and releasing the controller set button will display the current set point. To adjust the con-
troller set point press and hold the set key for three (3) seconds, the current set point will flash in the
display. Adjust the set point colder by pressing the down arrow key until point value shows in display.
Press the set key once for the controller to memorize the new set point. Be sure to allow 24 hours
between temperature controller adjustments.
Lighting
Viking uses state-of-the-art LED lighting, which is the most energy efficient light available. All units
have both a manual light switch on the controller (Fig. 4, page 22) and a door activated switch (Fig
5, page 22) centered under the door or drawer. The manual switch should be positioned in the off
position for normal operation. Check the door activated switch to ensure it is making sufficient con-
tact with the plunger bracket.
