Convertible freezers (freezer / refrigerator mode): Midea 2-in-1 uprights, Whirlpool WZCC convertible chest, Frigidaire convertible uprights: quick sheet

Covers: Stand-alone units that switch between freezer and refrigerator mode from the control: Midea 13.8 cu ft 28-in convertible 2-in-1 uprights (MU138 / MRU14 family and Ample 17 cu ft), Whirlpool WZCC5522TW-class convertible chest freezers, and Frigidaire convertible uprights such as FKCH17F7HW.

Single sourceBrands: Midea, Whirlpool, Frigidaire7 components

These units are increasingly common in garages. The mode is chosen at the control, not with a separate part, so 'my freezer is only fridge-cold' is often a mode setting. Garage ratings are mode-dependent: Whirlpool's convertible chest is listed garage-ready 0-110 F in freezer mode, and Midea lists a narrower ambient range in fridge mode (3-43 C) than in freezer mode (-18-43 C).

Safety first

  • Unplug before removing panels.
  • Sealed-system work is blocked (EPA 608).

How it works

One sealed system and one cabinet sensor serve both modes; the control simply uses a different setpoint band (Midea lists about -11 to 10 F in freezer mode and about 35-46 F in refrigerator mode).

Midea's upright is frost-free (fan and defrost system); Whirlpool's convertible chest is a chest design with a power / on-off indicator light.

In very cold garages a unit in fridge mode can stop running because the cabinet is already cold, which lets contents freeze or warms nothing; the low ambient limits in the spec sheet matter.

Freezer mode costs more to run than fridge mode (one reviewer measured roughly double on a Frigidaire convertible).

Diagnostic guides for this appliance

Guide · Freezer

Frost-free upright freezer: ice sheet on the freezer floor (defrost drain)

Defrost melt water is not reaching the drain pan, so it refreezes on the floor. The drain under the evaporator is clogged with debris or frozen shut, a drain heater/clip is missing or failed, or the liner is warped so water pools away from the hole.

Chest or upright freezer cabinet sides feel hot

On most chest freezers and many uprights the condenser tubing is bonded inside the outer walls, so warm sides are normal and keep the cabinet from sweating. It only matters if the warmth is extreme with poor cooling, or the unit runs constantly; then check clearance, ambient temperature, the door seal and any external condenser.

Freezer after a power outage: recovery check and food-safety triage (USDA guidance)

Per USDA / CDC guidance, a closed full freezer holds safe temperature about 48 hours and a half-full one about 24 hours. Food that still has ice crystals or is at 40 F or below can be refrozen (quality may drop); food above 40 F for more than 2 hours is discarded. Never taste to decide. Then confirm the freezer itself restarts and pulls down.
