Kenmore 79578312802 refrigerator Parts

On Kenmore model 79578312802, the ER FF code means the freezer evaporator fan is not running correctly, so cold air is not being moved from the freezer into the fresh food section. This can cause warm refrigerator temperatures even if the freezer seems cold. See the 79578312802 owner's manual.

What ER FF affects (and what you may notice)

• Refrigerator section warming up while the freezer stays closer to normal
• Little or no airflow from the top vents in the refrigerator compartment
• Unusual fan noise, rattling, or intermittent buzzing from the freezer area
• Frost or ice buildup that blocks airflow through the evaporator cover
• Temperature swings after adding groceries (airflow cannot recover quickly)

Quick checks we recommend before replacing parts

1. Power reset: Unplug the refrigerator for 5 minutes, then restore power.
2. Confirm doors are sealing and closing: A door left ajar can drive frost buildup and airflow problems.
3. Check for blocked vents: Make sure packages are not covering the air inlets/outlets.
4. Listen for the fan: With the freezer door closed, you should typically hear the evaporator fan running during cooling.
5. Look for heavy frost: If the freezer back wall is heavily frosted, the fan may be hitting ice or airflow is restricted.

Common causes and the most likely fixes

Likely cause	What it means	Typical fix
Ice buildup around evaporator fan	Fan cannot spin or airflow is blocked	Defrost and correct the root cause (door seal, defrost issue)
Failed defrost sensor	Defrost system cannot regulate properly	Replace the refrigerator defrost sensor assembly 6615JB2005C
Control or wiring issue	Fan not getting proper power/commands	Inspect connectors; test circuits; service as needed

Why it matters

This refrigerator relies on airflow to move cold air from the freezer to the fresh food compartment. When the evaporator fan system is compromised, temperatures rise, food spoils faster, and frost can build up and worsen the problem.

On Kenmore refrigerator model 79578312802, the ice maker is effectively “reset” by power-cycling the refrigerator and restarting the ice maker; the manual uses an ice maker power switch (OFF/ON) rather than a dedicated reset button. Use the steps below and confirm normal operation in the 79578312802 owner's manual.

Quick reset steps (power-cycle + restart)

• Turn the ice maker power switch to O (off).
• Unplug the refrigerator (or switch off the circuit breaker) for 5 minutes.
• Restore power.
• Turn the ice maker power switch to I (on).
• Wait for the freezer to reach 15°F (-9°C) or below; the ice maker starts automatically at that temperature.

If it still does not make ice

These checks match the most common “no ice” causes for this model:

• Water supply: Make sure the shutoff valve is fully open and the water line is connected.
• Freezer temperature: Allow 24 hours after changes for temperatures to stabilize.
• Ice bin cubes piled up: Level cubes by hand so the shutoff arm/sensor is not blocked.
• Recent power interruption: Keep doors closed as much as possible and allow time for recovery.
• Door not closing tightly: Warm air leaks can slow ice production; inspect the gasket and door alignment.

What “reset” does (and does not) do

Action	What it helps	What it won’t fix
Power-cycling the refrigerator	Clears minor control glitches and restarts the ice maker cycle	No water supply, failed valve, or a mechanical ice maker failure
Switching ice maker OFF then ON	Restarts ice maker operation after being turned off	Freezer too warm or bin/sensor blocked

Why it matters

Ice makers depend on steady freezer temperature and water flow. If the freezer is above 15°F (-9°C) or the water supply is restricted, the ice maker will not cycle even after a reset.

Kenmore refrigerator model 79578312802 is a bottom-freezer design in the Kenmore 795.7830_ / 795.7831_ series. For exact exterior dimensions (width, depth, height) and capacity for your specific color/version, we use the specifications listed in the 79578312802 owner's manual.

What “size” usually means for this model

When customers ask for the size of a refrigerator, it typically refers to one or more of these:

• Overall exterior dimensions: width, depth, and height (for fit in a cabinet opening)
• Total capacity: cubic feet (for storage planning)
• Door swing and clearance: space needed to open doors and pull out freezer drawers
• Installation clearances: airflow space around the cabinet

How to measure your refrigerator correctly

Use a tape measure and record in inches:

• Width: widest point of the cabinet (include hinges only if they stick out)
• Depth: from the back to the front of the doors/handles (note both “with handles” and “without handles” if needed)
• Height: floor to top of cabinet (include hinge cover if it’s the highest point)
• Clearance: space behind and above for ventilation and water line routing

Quick reference: what to write down

Measurement	What to include	Why it matters
Width	Cabinet (and hinges if they protrude)	Fit between cabinets
Depth	Doors and handles	Walkway clearance
Height	Highest point (often hinge area)	Overhead cabinet fit
Rear clearance	Space behind unit	Airflow and cord/water line

Why it matters

A bottom-mount refrigerator like the Kenmore 79578312802 needs enough room for proper air circulation and for the doors and freezer drawer to open fully. Accurate measurements prevent installation problems and help avoid warm temperatures caused by restricted airflow.
