What does CF mean on a Frigidaire refrigerator?
On the Frigidaire LFUS2613LF2, CF indicates the electronic control system is detecting a performance or communication problem, often tied to the control/display circuit. Start with a power reset and basic connection checks, then use the diagnostic guidance in the LFUS2613LF2 owner's manual.
- Power reset: Unplug the refrigerator (or switch off the breaker) for 5 minutes, then restore power.
- Confirm steady power: Make sure the wall outlet is on and the cord is fully seated.
- Check the water filter is fully seated: A filter that is not clicked in can cause operating issues; the front of the filter should sit flush.
- Watch the display: If the display continues flashing or CF returns quickly, the control system is still seeing the fault.
- Note symptoms: Warm temperatures, no cooling, or unusual cycling helps narrow the cause.
CF is commonly associated with a control-side issue such as a loose connection, damaged wiring, or a failing electronic control.
| What you see | What it often means | What to try next |
|---|---|---|
| CF appears after a power event | Control needs to reboot | Power reset, then monitor 24 hours for temperature stability |
| CF with flashing temperature display | Control detected a performance problem | Follow troubleshooting steps in the manual; plan for control diagnostics |
| CF plus warm fridge/freezer | Cooling system not being managed correctly | Check condenser cleanliness and airflow; move to fan/control checks |
If CF persists after the quick checks, diagnosis often focuses on control and temperature-sensing circuits.
- Temperature sensing: A failed sensor can feed bad data to the control; see refrigerator temperature sensor 240597220.
- Main control: A failing board can trigger repeated faults; see refrigerator electronic control board 241739710.
- Cooling airflow: If the evaporator fan is not moving air, temperatures can drift and faults can follow; see refrigerator evaporator motor 242077705.
A CF condition can prevent the refrigerator from maintaining safe food temperatures. Addressing it quickly helps protect food, reduces compressor run time, and prevents repeat icing or airflow problems.

What are the most common issues with LFUS2613LF2?
The most common issues we see with the Frigidaire LFUS2613LF2 side-by-side refrigerator involve cooling performance, ice maker and water dispenser problems, frost buildup from defrost failures, and door sealing issues. Many of these symptoms trace back to airflow, filtration, or temperature-sensing components.
- Warm refrigerator or freezer: restricted airflow, evaporator fan issue, dirty condenser area, or a control/sensor problem
- No ice or small/hollow cubes: clogged filter, low water pressure, air in the line, or ice maker component wear
- Water dispenser slow or not dispensing: filter restriction, air trapped in the line, or supply issue
- Frost buildup on the back wall: defrost system problem (thermostat, heater circuit, or control)
- Moisture, sweating, or leaks at the doors: door gasket not sealing or doors out of alignment
- Confirm temperature settings and allow 24 hours after any adjustment.
- Make sure vents inside both compartments are not blocked by food packages.
- Replace the water filter on schedule; for this model, the refrigerator water filter WF3CB is a common maintenance item.
- Inspect door gaskets for gaps, tears, or hardened sections; this model uses options such as the refrigerator door gasket (white) 241786013 and refrigerator freezer door gasket (gray) 241786014.
- Listen for the evaporator fan; if you hear grinding or no fan sound during cooling, the fan motor or blade can be involved.
| Symptom | Most likely area | Example part on this model |
|---|---|---|
| Poor cooling, warm temps | Airflow in freezer section | Refrigerator evaporator motor (242077705), fan blade (5308000010) |
| Frost buildup | Defrost system | Refrigerator defrost bi-metal thermostat 5303918214 |
| Bad taste/slow water | Filtration/water flow | Refrigerator water filter WF3CB |
| Door not sealing | Door gasket | Refrigerator freezer door gasket (gray) 241786014 |
Catching these issues early protects food safety, prevents heavy frost that blocks airflow, and reduces strain on major sealed-system components like the compressor.

How do I find the model number on my LFUS2613LF2?
The model number for your Frigidaire side-by-side refrigerator is printed on the appliance ID label, not on the control panel. On LFUS2613LF2 units, the label is typically inside the fresh food (refrigerator) compartment on a side wall; confirm the exact location in the owner's manual.
Check these common ID-label locations first:
- Inside the fresh food compartment on the left or right side wall
- On the ceiling of the fresh food compartment near the temperature controls
- Behind the crisper drawers on the side wall
- On the hinge-side door frame area (open the refrigerator door and look around the frame)
- On the back exterior panel near the lower section
We recommend copying the information exactly as shown on the label:
- Model number (example: LFUS2613LF2)
- Serial number (used to identify production run)
- Electrical ratings (volts/amps) if you are troubleshooting power issues
| Item on label | What it’s used for | Why it matters |
|---|---|---|
| Model number | Parts lookup and diagrams | Ensures correct fit for items like a door gasket or control board |
| Serial number | Manufacturing date/series | Helps match revisions when designs change |
Frigidaire often uses similar-looking cabinets across multiple model numbers; one character difference can change the correct door gasket, electronic control board, or water filter fitment. Using the exact LFUS2613LF2 model number prevents ordering the wrong part.
