TROUBLE SHOOTING
Cleaning and Maintenance
Warning: To avoid electric shock always unplug your wine cellar before cleaning,
Ignoring this warning may result in death or injury.
Caution: Before using cleaning products, always read and follow manufacture’s
instructions and warnings to avoid personal injury or product damage.
General:
z Prepare a cleaning solution of 3-4 tablespoons of baking soda mixed with
warm water, Use sponge or soft cloth, dampened with the cleaning solution,
to wipe down your wine cellar.
z Rinse with clean warm water and dry with a soft cloth.
z Do not use harsh chemicals, abrasives, ammonia, chlorine bleach,
concentrated detergent solvents or metal scouting pads ,SOME of these
chemical may dissolve , damage and/or discolor your wine cellar.
Door Gaskets:
z Clean door gaskets every three months according to general instructions,
Gaskets must be kept clean and
pliable to assure a proper seal,
z Petroleum jelly applied lightly on the hinge side of gaskets will keep the
gasket pliable and assure a good seal.
Power Interruptions
z Occasionally there may be power interruptions due to thunderstorms or other
２３
TROUBLE SHOOTING
causes, Remove the power cord from AC outlet when a power outage occurs,
When power has been restored , plug power cord to AC outlet again.
Vacation and Moving Care
z For ling vacations or absences ,unplug the wine cellar and clean the wine
cellar and door gaskets according to “General cleaning “ section, Prop doors
open, so air can circulate inside. When moving always move the wine cellar
vertically, Do not move with the unit lying down, Possible damage to the
sealed system could occur.
Normal Operating Sounds You May Hear
z Boiling water, gurgling sounds or slight vibrations that are the result of the
refrigerant circulating through the cooling coils.
z The thermostat control will click when it cycles on and off.
Wine Cellar Does Not Operate
z Check if wine cellar is plugged in.
z Check if there is power at the ac outlet ,by checking the circuit breaker.
Wine appears too warm
z Frequent door openings.
z Allow time for recently added wine to reach desired temperature.
z Check gaskets for proper seal.
z Clean condenser coils.
z Adjust temperature control to colder setting.
２４
TROUBLE SHOOTING
Wine temperature is too cold.
z If temperature control setting is too cold, adjust to a warmer setting.
Wine cellar runs too frequently
z This may be normal to maintain constant temperature during high
temperature and humid days.
z Doors may have been opened frequently or for an extended period of time .
z Clean condenser coils,
z Check gasket for proper seal.
z Check to see if doors are completely closed.
Moisture build up on interior or exterior of the wine cellar:
z This is normal during high humidity periods.
z Prolonged or frequent door openings.
z Check door gaskets for proper seal.
Wine Cellar door does not shut properly:
z Level the wine cellar.
z Check for blockages e.g. wine bottles, shelves.

airflow is impeded.
4. The frost layer at the
evaporator is too thick.
5. The refrigerant is insufficient
or leakage.
6. Compressor efficiency is
reduced.
7. The drying filter is blocked.
1. The point of sensor was moved.
2.The temperature sensing probe
of controller is not placed well, and
causes maladjustment
3.Compressor efficiency reduced.
２６
Removing methods
1. Check if there is short circuit
and solve it, if not, change capable
fuse
2. Check and connect tightly, or
change.
3. Use till voltage rises to rated
value or attach a stabilizer.
4. Rotate the knob to wanted
position for suitable temperature.
5. Change the controller.
6. Change starting relay or thermal
protection unit.
7. Measure using R×1 position of
avometer, if there is wire broken,
change compressor.
8. Change compressor.
9. Change compressor.
1 Check the point of sensor,and
move it to original place.
2.Change the temperature

3.Put the wine cellar to suitable
place and make air circulate well.
4Remove frost regularly.
5.Check or supplement refrigerant.
6.Change compressor.
7.Change new drying filter.
1.Check the point of sensor,and
move it to original place.
2.Adjust to suitable position,
normally contact tightly with
