section in this manual for      

issues pertaining to case location.  Wide temperature fluctuation   
can take place in certain environments. 

Not Holding Temperature 

If a large amount of warm product was added to the case, it will take 
time for the temperature to adjust.  Unit needs pre-chilled product. 

 

The temperature will change during defrost cycle but will return to 
normal when compressor turns on.   

 

Check to see if the condenser coil has been cleaned. 

 

Check that the case is not in the sun or near a heat or                             
air-conditioning vent.

 grilles for obstruction and remove. 

 

Ensure that front air grilles are not obstructed by product or other 
décor.

run warm and will negate warranty.

Check that the main power switch is turned on.

 

 

Check that case is on and the control display is not blank.  If blank, 
call toll-free number at end of manual. 

 

Controller may be in defrost mode. Compressor cycling on and off is 
a normal condition.  Carel® Temperature Controller Section in this 
manual. 

Not Holding Temperature 

Check that the coil fans are working. 

 

Check that  the discharge air is not disrupted or blocked by product. 

 

If a large amount of warm product was added to the case, it will take 
time for the temperature to adjust. 

 

Check the coil for ice build up. 

 

Check that the condenser coil is clean. 

 

Check that the case is not in the sun or near a heat or air                
conditioning vent. 

 

Case temperature will rise during defrost mode but will return to      
normal.  Proper product temperature will  be maintained.
