How do I reset the freezer on a Frigidaire refrigerator?
For a Frigidaire LFFU14F5HWL upright freezer, the most reliable reset is a power reset: unplug the unit, wait about 1 minute, then plug it back in. If the control is locked or an alarm is active, use the control panel steps in the LFFU14F5HWL owner's manual to restore normal operation.
- Unplug the freezer from the wall outlet (do not use a wall switch-controlled outlet).
- Wait 60 seconds so the control can fully power down.
- Plug the freezer back in firmly.
- If the alarm sounds, press Alarm Reset to silence it.
- Allow time for temperatures to stabilize after power is restored.
This model can lock the temperature control to prevent accidental changes.
- Press and hold Alarm Reset for 3 seconds to toggle the control lock.
- Watch the display for the lock/unlock indicator, then re-check your temperature setting.
On this style of electronic control, turning the temperature setting to OFF/0 stops the compressor but does not disconnect power to other components (such as the light).
| What you see | What it usually means | What to do |
|---|---|---|
| Display shows “0” | Compressor is off | Press UP to reactivate, then set temperature |
| “HI TEMP” light on | Freezer is above about 23°F | Press Alarm Reset, keep door closed |
| “Door Ajar” light | Door open too long | Close door fully, check gasket seal |
A proper reset clears minor control glitches and restores normal cycling. If the freezer still will not cool after a reset, common causes include airflow problems (evaporator fan), a defrost system issue, or a door seal leak. For cooling and airflow symptoms, we often see fixes involving the freezer evaporator fan motor 297309000 or the defrost heater 5304496687.

How big is a 6.5 cu ft upright freezer?
A typical 6.5 cu ft upright freezer is a compact, apartment-size unit that usually stands about 55 to 60 inches tall and about 21 to 24 inches wide and deep. For exact dimensions and required clearance, use the LFFU14F5HWL owner's manual for your Frigidaire LFFU14F5HWL.
Most 6.5 cu ft uprights fall into this general footprint range:
- Height: ~55 to 60 in.
- Width: ~21 to 24 in.
- Depth: ~21 to 24 in. (not including handle)
- Door swing clearance: plan extra space on the hinge side
Even when the cabinet fits, the freezer still needs room to work correctly.
- Leave space around the cabinet for air circulation
- Make sure the freezer sits on a solid, level floor
- Confirm the door can close and seal; leveling affects alignment
- Account for the handle and any trim that adds depth
- Verify you can fully open the door to remove baskets and shelves
| What you are measuring | What to include | Why it matters |
|---|---|---|
| Cabinet footprint | width, depth, height | ensures it physically fits |
| Operating clearance | space around sides/back/top | helps cooling and efficiency |
| Door swing | arc of the door | prevents binding and poor access |
| Floor level | front-to-back level | helps the door seal properly |
If an upright freezer is tight in a nook or not level, the door can end up slightly misaligned and not seal well. That leads to frost buildup, moisture, and longer run times. The manual also emphasizes allowing enough space for airflow, especially in hotter areas.

What is the best setting for a Frigidaire freezer?
For your Frigidaire LFFU14F5HWL upright freezer, the best everyday target is 0°F (-18°C) for safe long-term food storage. Set the temperature control to reach that target, then give the freezer several hours to stabilize between adjustments (details are in the LFFU14F5HWL owner's manual).
Your freezer may use either a dial (electromechanical control) or an electronic control panel. In both cases, make small changes and wait for the temperature to settle.
- Dial control: turn the knob clockwise or counterclockwise to adjust.
- Electronic control: press UP for colder and DOWN for warmer.
- Wait several hours between changes so the cabinet temperature can stabilize.
- After first start-up, allow about 4 hours for the freezer to cool completely before loading unfrozen food.
If your freezer is too warm or too cold, these checks fix most issues without replacing parts.
- Confirm the door closes fully and is not held open by packages.
- Open the door less often; warm air makes the freezer run longer.
- Make sure there is 3 inches of air space on all sides for airflow.
- Avoid using an extension cord; plug into a grounded outlet.
- If the door seal is leaking, inspect the gasket for gaps, tears, or hard spots.
| Situation | What’s normal | What to do |
|---|---|---|
| You just adjusted the control | Temperature changes slowly | Wait several hours before adjusting again |
| First day of operation | Longer run time | Allow about 4 hours to cool fully |
| Room is hot (up to 110°F) | Freezer runs more | Improve ventilation and reduce door openings |
| Outside walls feel warm | Can be up to ~30°F warmer than room temp | Normal compressor heat transfer |
Keeping the freezer near 0°F helps food stay frozen solid, reduces freezer burn risk, and prevents unnecessary compressor run time caused by frequent over-adjusting.
If you need replacement parts for cooling or sealing issues, you can order model-matched parts from the list for LFFU14F5HWL or search by model on Sears PartsDirect.

What does H mean on a Frigidaire freezer?
On a Frigidaire LFFU14F5HWL upright freezer, H (sometimes shown as HI or High Temp) indicates a high-temperature alarm; the freezer temperature rose above the set threshold. The most common cause is the door being left open or not sealing tightly, letting warm air in.
- Confirm the door closes fully and nothing is blocking it (baskets, packages)
- Inspect the door gasket for gaps, rips, or areas not contacting the cabinet
- Make sure the freezer is level so the door aligns and seals correctly
- Limit door openings until the temperature recovers
- Allow several hours for temperatures to stabilize after closing the door or changing settings
Use the control steps and alarm reset guidance in the LFFU14F5HWL owner's manual. On many Frigidaire upright freezers, the display and cabinet temperature take time to return to normal after an alarm.
| What you notice | Likely cause | What to do |
|---|---|---|
| H after loading food | Warm load, door open too long | Reduce openings; allow recovery time |
| Moisture or frost near door | Door not sealing | Re-seat/clean gasket; check alignment |
| Weak cooling plus heavy frost | Defrost problem | Check for heavy frost on the back wall |
| Warm temps with normal frost | Airflow issue | Listen for evaporator fan operation |
If you find heavy frost buildup or weak airflow, these model-compatible parts are often involved:
- Defrost heater 5304496687 melts frost off the evaporator during defrost
- Refrigeration appliance defrost bi-metal thermostat 297216600 helps regulate defrost heating
- Freezer evaporator fan motor 297309000 circulates cold air through the cabinet
A high-temp condition can soften frozen food and force longer compressor run times. Correcting door sealing, airflow, or defrost issues quickly helps restore stable temperatures and efficiency.
