What is the life expectancy of a Frigidaire upright freezer?
A Frigidaire upright freezer like model FFU17F5HWU typically lasts 10 to 15 years. With good basics such as proper air circulation, correct leveling so the door seals, and routine cleaning, many upright freezers reach the high end of that range.
We see the longest-lasting freezers when these habits are consistent:
- Keep enough space around the cabinet for air circulation (especially in hot rooms)
- Level the freezer so the door closes and seals easily
- Keep the door gasket clean so it seals without gaps
- Defrost and clean when frost buildup reaches about 1/4 to 1/2 inch (manual-defrost models)
- Avoid using sharp tools on interior surfaces or fast-freeze shelves
- Limit long door openings to reduce warm, moist air entering the freezer
For model-specific use and care details, follow the FFU17F5HWU owner’s manual.
| Task | How often | Why it matters |
|---|---|---|
| Check door closing and seal | Monthly | Prevents moisture, frost, and temperature swings |
| Clean interior spills | As needed | Reduces odors and helps the gasket seal |
| Defrost (if applicable) | At 1/4 to 1/2 inch frost | Keeps airflow and cooling efficient |
| Verify freezer is level | After moving, then yearly | Helps the door align and seal properly |
Most “early failures” are really stress from poor ventilation, a door that does not seal, or heavy frost buildup. Those conditions make the compressor and evaporator system run longer and harder, which shortens overall freezer life.

How do I reset my Frigidaire upright freezer?
To reset your Frigidaire FFU17F5HWU upright freezer, we recommend doing a simple power reset: unplug the freezer (or turn off the breaker) for about 1 minute, then restore power and allow the temperature to stabilize for several hours.
- Unplug the freezer from the wall outlet, or switch the circuit breaker off.
- Wait 60 seconds.
- Plug the freezer back in, or switch the breaker on.
- Confirm the display and interior light come back on.
- Let the freezer run several hours before judging temperature changes.
This model can lock the control panel so settings cannot be changed. If buttons do not respond, unlock the controls using the steps in the FFU17F5HWU owner's manual.
- Press and hold Alarm Reset for 3 seconds to lock or unlock.
- When unlocking, you may briefly see a “U” on the display, then the temperature.
A reset restores normal operation, but it will not fix airflow or sealing problems. Use this checklist to confirm the freezer can cool correctly:
- Door closes and seals fully (no gaps or warm air leaks).
- Freezer is level so the door aligns and shuts easily.
- Air can circulate around the cabinet (do not block vents or pack items tightly).
- Temperature setting is not at 0 (off).
- Alarms: press Alarm Reset to silence a temp or door-ajar alarm.
| Symptom after reset | Most likely cause | What we recommend |
|---|---|---|
| Display shows 0 | Unit is set to off | Press UP until display shows 1, then set colder |
| Buttons do nothing | Control lock is on | Hold Alarm Reset 3 seconds |
| “Door Ajar” alarm | Door not fully closed | Re-seat shelves/bins, confirm gasket contact |
| “HI TEMP” alarm | Warm cabinet after power loss | Let it run; alarm clears when below about 23°F |
A power reset clears minor control glitches and restarts the cooling cycle, but proper leveling and a good door seal are what prevent frost, moisture, and temperature swings over time.

Why is my Frigidaire upright freezer not freezing?
If your Frigidaire FFU17F5HWU upright freezer isn’t freezing, the most common causes are the temperature control being set incorrectly or OFF, poor airflow from installation or dirty coils, a door that isn’t sealing, or a failed cooling/air-circulation component such as the evaporator fan motor. Use the FFU17F5HWU owner’s manual troubleshooting checks first.
- Confirm the temperature control is not set to OFF and allow 24 hours after any adjustment for temperatures to stabilize.
- Make sure the freezer is level so the door closes and seals properly (an unlevel cabinet can cause cooling and moisture problems).
- Check that the door closes fully and isn’t being held open by a bin, shelf, or food package.
- Reduce door openings and avoid loading large amounts of warm food at once.
- Verify there is enough space around the cabinet for air circulation, especially in hot rooms.
If the quick checks look good, these are the most common failures that stop freezing:
- Evaporator fan not running (no cold air circulation inside the cabinet): consider the freezer evaporator fan motor 297309000.
- Heavy frost buildup on the evaporator area (defrost system problem): the defrost heater may be involved, such as defrost heat 5304496284.
- Door gasket leaking (warm air intrusion, frost, weak cooling): inspect the freezer door gasket 5304507200 for gaps, tears, or a poor fit.
- Compressor not starting (clicking, warm cabinet): a start device may be involved, such as the freezer start relay 297259515.
| What you notice | Most likely cause | What to do |
|---|---|---|
| Runs a lot but still warm | Door not sealing, warm room, airflow issue | Level cabinet, check gasket, improve ventilation |
| Frost/ice buildup inside | Door leak or defrost issue | Check gasket; inspect defrost system |
| Quiet, no fan sound | Evaporator fan problem | Test/replace fan motor |
| Clicking near compressor | Start relay/capacitor issue | Inspect start components |
A freezer that is slightly unlevel or not sealing lets warm, moist air in; that creates frost, forces longer run times, and can prevent the FFU17F5HWU from reaching safe food-storage temperatures.
