Check instructions in the temperature controller section of this manual
for your particular temperature controller.
Not Holding Temperature
If a large amount of warm product was added to the case, it will take
time for the temperature to adjust.
The temperature will change during defrost mode but will return to
normal.
Check that the discharge air is not disrupted or blocked by product
(Product is above load limit level).
Check that the case is not in the sun or near a heat or air-conditioning
vent.
Is case located near front doors? Wide ranging temperature fluctuation
can occur if inside temperatures widely vary from outside temperatures.
Check the evaporator coil for ice build up (can be viewed from fan
shroud inspection cover).
