TROUBLESHOOTING

In the unlikely event you lose cooling in your unit, do not
unplug the product from the electric supply, but do call
a qualifi ed service technician immediately. It is possible
that the loss of cooling capacity is a result of excessive
frost build-up on the evaporator cooling coil. In this case,
removing power to the unit will result in the melting of this
excessive quantity of ice, which could generate melt water
that exceeds the capacity of the defrost drain system and
could result in water damage to your home. The end-user
will be ultimately responsible for any water damage caused
by prematurely turning the unit off without appropriately
managing the excess water run-off.
Possible Cause
• Control set too warm
• Content temperature not stabi-
lized.
• Excessive usage or prolonged
door openings.
• Airfl ow to front grille blocked.
• Door gasket not sealing properly.
• Control set too cold
• Door gasket not sealing properly.
• Failed LED light assembly or light
switch.
• Display light is turned on. (Glass
door models only.
• Door not activating light switch.
• Failed light switch
• Appliance not level
• Fan hitting tube obstruction.
• Appliance turned off
