If the freezer of the Whirlpool WRF757SDHZ is not cold enough, Whirlpool's guide and help article give the same order of checks: allow 24 hours after installation and do not add food before the refrigerator has cooled completely, check cooling is turned on (LOCK and FAST ICE pressed together for 3 seconds toggles it, and Cooling Off blinks seven times), confirm the freezer set point is 0 F (range -5 to 5 F) and that adjusting to a colder setting will not cool faster, check the air vents are not blocked and keep doors and the drawer closed. Frost or too little ice can also mean a warm setting: the chart says freezer too warm means a setting 1 degree lower.

ReversibleThe guide says to wait 24 hours before putting food in a new refrigerator; adding food before it has cooled completely may spoil it.
Check that cooling is on
ReversibleThe refrigerator and freezer will not cool when cooling is turned off. Press and hold LOCK and FAST ICE together for 3 seconds; when cooling is off, only Lock and Fast Ice are enabled.
Check the set point
ReversiblePress and hold TEMP for 3 seconds, press TEMP to choose Freezer, and use LOCK to raise or OPTIONS to lower the set point. Freezer too warm or too little ice means a setting 1 degree lower; the range is -5 to 5 F.
Clear the vents
ReversibleIf the temperature is too warm or cold, first check the air vents are not blocked before adjusting controls.
Confirm the settings
ReversibleWhen finished press FAST ICE to confirm and save. Wait at least 24 hours between adjustments and recheck.
