Case Lights Are 

Not Working 

See 

TROUBLESHOOTING (TO BE PERFORMED BY STORE PERSONNEL)

         

section in manual (previous sheet) for most common troubleshooting solutions. 

 

Check power.  

 

If power is not supplied to the case, facility may have faulty power distribution.

 

 

If power is supplied to the case but lights are not energized, case’s power supply 

may be faulty.

 

Case Is 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 product to be pre-chilled. 

 

Temperature changes during defrost mode but will return to normal. Fourth LED will 

indicate defrost cycle in progress. 

 

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

 

If case is located near outside doors, temperature fluctuation can hinder unit’s ability 

to maintain temperature. 

 

Check that condenser coil has been cleaned. 

 

Check that magnetic air filter (attached to air intake grille) has been cleaned.                   

See 

CLEANING SCHEDULE (TO BE PERFORMED BY STORE PERSONNEL) 

 section in operating manual for instructions. 

 

Check return air grilles for obstructions. 

 

Check sight glass for flashing and/or low charge. 

 

Check set point temperature; it may be adjusted too high.
