Section 7 – Operator Preventive Maintenance:
NOTE: Before attempting service, failure diagnosis or component
repairs, verify basic operator maintenance has been done.
PROBLEM: Freezer is running but will not reach 0 F [-18 C] or
lower. High temperatures caused by a dirty condenser coil,
blocking the front or side louvered panels or direct contact with
the Grill Station may cause the freezer to function improperly, not
maintain temperature or cease operating.
1) FIRST- Perform a Manual Defrost: Push and HOLD (for
five seconds) the lower button to the left of temperature
display. Display will read: dEF.
2) Open the front compartment door and verify that freezer has
been defrosted. If significant ice buildup is still present, turn
OFF rear power switch, open the freezer compartment door
and allow the ice to melt.
3) Check to see if freezer is overloaded or if plastic carton
liners are obstructing evaporator fan openings.
4) Check freezer door gasket for damage. If damage is found,
replace the door gasket.
5) Check rear and side clearance around unit. To operate
efficiently, the following clearances are recommended:
HCMF-18 0” (2” recommended) 1” (2” recommended)
HCMF-30 0” (2” recommended) 1” (2” recommended)
6) Pull off front louvered access panel. Inspect the condenser
coil to ensure it is clean and free of dust and debris. If it is
dirty, clean it with a soft bristle brush or portable vacuum.
7) Test unit for operation within the 0 to -10 F [-18 to -23 C]
normal operating temperature range.
8) If these steps correct problem, notify unit manager of
problems noted with crew cleaning, operator preventive
maintenance or location of unit. If problem persists, see
Troubleshooting Guide.
