  • Frost-Free defrost
  • Temperature alarm
  • Adjustable temperature control

The Whirlpool WZF79R20DW is a current upright freezer. About 19.6 cu ft in a 33.25"W x 66.75"H x 30"D cabinet, frost-free with a temperature alarm to warn of warming in a white finish.

Upright and chest freezers are setpoint controlled and diagnosed by symptom: not freezing, frost buildup, running constantly, or a failed start relay or thermostat. See freezer repair. For full specifications and model lookup, visit whirlpool.com.
