How do I reset my Frigidaire upright freezer?
To reset your Frigidaire upright freezer model FFFH20F2QWF, we recommend doing a power reset by unplugging the unit (or switching off the breaker) briefly, then restoring power. If the control panel is in Power Off, Control Lock, or Sabbath mode, you may need to exit that mode instead of unplugging. See the FFFH20F2QWF owner’s manual for the exact control-panel steps.
- Unplug the freezer from the wall outlet (or turn the circuit breaker off).
- Wait 30 to 60 seconds.
- Plug the freezer back in (or turn the breaker on).
- Allow the control panel to power up; cooling may take a few minutes to restart.
- For safe food storage, allow up to 4 hours for temperatures to stabilize after a full shutdown.
On this model, the control panel can place the freezer into a powered-off state without removing electrical power.
- Exit Power Off mode: enter the options menu, highlight power off, then press and hold Set for about 3 seconds.
- Unlock controls: press and hold Set for about 3 seconds.
- Exit Sabbath mode: press and hold Options and + for about 5 seconds.
| What you see | What it usually means | What to try |
|---|---|---|
| “power fail” on display | Power was interrupted | Press Set (or any key) to acknowledge |
| Alarm sounding | High temp, power fail, or door ajar | Close door; press Set to acknowledge |
| Buttons don’t respond | Control lock or Sabbath mode | Use the unlock or Sabbath exit steps above |
A true reset clears temporary control glitches after a power interruption, but many “won’t start” complaints are actually the freezer being set to Power Off or the controls being locked. Using the correct reset method helps you restore cooling faster and protect frozen food.

What temperature should my Frigidaire upright freezer be set at?
For the Frigidaire FFFH20F2QWF upright freezer, we recommend setting the freezer temperature to 0°F (-18°C) for safe long-term food storage. After any adjustment, give the freezer several hours to stabilize before changing the setting again. See the FFFH20F2QWF use & care manual for control details.
Use these steps to get consistent temperatures:
- Place a freezer thermometer in the center of the cabinet (not in the door bin).
- Set the control to the normal recommended setting, then wait 24 hours.
- Adjust in small steps; wait several hours between adjustments.
- Keep the door closed as much as possible while temperatures stabilize.
- Avoid overpacking; blocked airflow can cause warm spots.
| Situation | What you may notice | What we recommend |
|---|---|---|
| First start-up | Unit may run for hours | Allow about 4 hours to cool down before loading unfrozen food |
| After changing the control | Temperature swings for a while | Recheck after 24 hours |
| Adding lots of room-temp food | Longer run time | Spread items out; do not keep opening the door |
Keeping your FFFH20F2QWF at 0°F helps food stay solidly frozen, reduces freezer burn risk, and supports safe storage times. Warmer settings can lead to softening, ice crystals melting and refreezing, and faster quality loss.
If you cannot reach or maintain 0°F after 24 hours, check these common causes:
- Door not sealing fully (gasket gaps, packages blocking closure)
- Frequent door openings or door left ajar
- Control locked or special modes active (if equipped)
- Heavy frost buildup restricting airflow
- Dirty or damaged cooling components
If you suspect a sealing issue, a compatible replacement may be listed for this model, such as the gasket,white 5304506131.

Why is my Frigidaire upright freezer not freezing?
If your Frigidaire FFFH20F2QWF upright freezer is running but not freezing, the most common causes are warm air leaking in through the door seal, restricted airflow from frost buildup, or a temperature control issue. Start with the simple checks in the FFFH20F2QWF owner’s manual before replacing parts.
- Confirm the control is not in POWER OFF and the setpoint is set colder; allow several hours to stabilize.
- Make sure Quick Freeze is not masking a cooling problem (it runs for 72 hours, then returns to normal).
- Check for Door Ajar and verify the door closes tightly.
- Allow a full 4 hours after startup or a move for the freezer to cool down.
- Reduce door openings and avoid loading large amounts of warm food at once.
Warm air leaks and blocked airflow can keep temperatures above freezing even when the compressor runs.
What to look for
- Gaps, tears, or hardened areas on the door gasket
- Frost or ice buildup that blocks vents or the evaporator area
- Packages sticking out past shelves that prevent the door from sealing
Parts that often solve these issues (when symptoms match)
- If the door seal is damaged or leaking: gasket,white 5304506131
- If the freezer is not circulating cold air and you do not hear the fan running: Frigidaire freezer evaporator fan motor 297309000
If the freezer cools a little but cannot maintain freezing temps, a control or defrost problem may be involved.
| Symptom | More likely cause | What we do next |
|---|---|---|
| Temps drift warmer over time | Temperature control issue | Test/replace thermostat if it is not cycling correctly |
| Heavy frost, weak airflow | Defrost system issue | Inspect heater/timer and check for ice blocking airflow |
Relevant parts for this model include:
- Freezer temperature control thermostat 5304513033
- Defrost timer 5304518034
- White-westinghouse freezer defrost heater 5304496284
When the FFFH20F2QWF cannot freeze, food safety and compressor run time are the biggest concerns. Fixing air leaks, restoring airflow, and correcting control/defrost problems helps the freezer reach and hold safe storage temperatures.
