What does H mean on a Frigidaire freezer?
On the Frigidaire FFU14F5HWN upright freezer, H or HI means a high temperature alarm. It indicates the freezer temperature has been too warm for a period of time, most often because the door was left open or not sealing tightly.
What to do right away
- Make sure the freezer door is fully closed and not blocked by baskets, shelves, or packages.
- Check the door seal for gaps, folds, or frost buildup along the gasket.
- Press Alarm Reset (if your control has it) to silence the alarm, then allow several hours for temperatures to stabilize.
- Avoid repeated door openings while the freezer pulls back down to temperature.
- If the display shows an E code, schedule service because that indicates a control-related fault.
Common causes of an H/HI alarm
| Likely cause | What you will notice | What usually fixes it |
|---|---|---|
| Door left ajar | Alarm after loading food | Close door; wait for recovery |
| Door not sealing | Frost or moisture near door | Clean gasket and sealing surfaces |
| Warm food load | Temp rises after stocking | Let food cool first; give recovery time |
| Airflow blocked | Some areas warmer than others | Reorganize to keep vents clear |
Why it matters
A high-temp condition can soften or partially thaw frozen food and can also increase frost buildup, which makes the freezer work harder and can lead to more frequent alarms.
Model-specific tips for FFU14F5HWN controls
- Temperature changes are made on the control; allow several hours between adjustments for the temperature to stabilize.
- If your control panel locks, press and hold Alarm Reset for about 3 seconds to lock or unlock (depending on current state). See the FFU14F5HWN manual for the exact control layout on your version.

How big is a 14.1 cubic foot freezer?
A 14.1 cubic foot upright freezer is a mid-size unit that typically stands about 60 to 65 inches tall, is about 28 to 32 inches wide, and about 28 to 32 inches deep. For your Frigidaire FFU14F5HWN, use the exact cabinet dimensions and clearance guidance in the FFU14F5HWN owner's manual.
What “14.1 cubic feet” means
Cubic feet is interior storage volume, not the outside size. The exterior dimensions are always larger because they include insulation, the cabinet, and the door.
What you can expect from this size class:
- Enough capacity for bulk frozen foods, boxed items, and stacked packages
- Several fixed shelves and door storage (varies by model)
- A footprint similar to many 28 to 32 inch wide upright freezers
Space you should plan for (important)
Your FFU14F5HWN needs airflow around the cabinet for efficient cooling. The manual calls for 3 inches of air space on all sides.
- Leave 3 inches on the left side
- Leave 3 inches on the right side
- Leave 3 inches behind the freezer
- Leave 3 inches above (if possible) to help heat escape
- Avoid tight closets or alcoves without ventilation
Quick sizing checklist
Use this to confirm fit before delivery or moving the freezer into place.
| What to measure | How to measure | Why it matters |
|---|---|---|
| Doorway width | Narrowest point (trim included) | Prevents getting stuck at entry |
| Hallway turns | Corner-to-corner clearance | Avoids cabinet damage |
| Final location | Width, depth, height plus 3 inch clearance | Ensures proper airflow |
| Door swing | Space for full door opening | Access to baskets and shelves |
Why it matters
If the freezer is squeezed into a tight space, it can run hotter, cycle longer, and struggle to hold temperature. Proper clearance also helps reduce condensation and keeps the compressor area from overheating.

Why is my Frigidaire upright freezer not freezing?
If your Frigidaire FFU14F5HWN upright freezer is not freezing, the most common causes are the temperature control being set incorrectly, poor airflow from dirty coils or blocked vents, a door that is not sealing, or a failed airflow/defrost component. Use the checks below and confirm the correct settings in the FFU14F5HWN owner's manual.
Quick checks we recommend first
- Make sure the temperature control is not set to OFF and is set cold enough for freezing.
- Keep the door closed as much as possible; frequent openings quickly warm the cabinet.
- Confirm the freezer is level so the door closes and seals properly (an unlevel cabinet can cause cooling and moisture problems).
- Allow enough space around the freezer for air circulation, especially in hot rooms.
- If the freezer was recently unplugged or loaded with warm food, give it time to pull down temperature.
Airflow and frost issues (most common on uprights)
Cold air has to move through the cabinet. If airflow is weak, temperatures rise even if the compressor runs.
- If you hear the fan struggling, rattling, or not running, inspect the evaporator fan area; a damaged fan blade can reduce circulation.
- If you see heavy frost buildup inside, the defrost system may not be clearing frost from the evaporator.
Helpful parts to consider when symptoms match:
- Blade 5308000010 (if the fan is noisy, wobbling, or not moving air)
- Frigidaire freezer evaporator fan motor 297309000 (if the fan is not running)
- Freezer defrost heater 5304496687 or refrigeration appliance defrost bi-metal thermostat 297216600 (if frost buildup is blocking airflow)
What the symptoms usually mean
| Symptom | Most likely area to check | What to do next |
|---|---|---|
| Runs a lot but not cold | Airflow, door seal, dirty coils | Improve airflow, verify door closes, clean coils |
| Frost wall or snow buildup | Defrost system | Inspect heater/thermostat, fully defrost to restore airflow |
| No fan sound inside | Evaporator fan | Check blade and motor |
| Door pops open or doesn’t seal | Leveling, gasket | Level cabinet; inspect gasket for gaps |
Why it matters
A freezer that is slightly unlevel or has a small air leak can pull in warm, moist air; that drives frost buildup, reduces airflow, and prevents the FFU14F5HWN from reaching safe freezing temperatures.

How do I reset my Frigidaire upright freezer?
To reset your Frigidaire FFU14F5HWN upright freezer, power-cycle it: unplug the unit for about 1 minute, then plug it back in and allow several hours for temperatures to stabilize. This clears many control glitches and restores normal operation.
Quick reset steps (power-cycle)
- Unplug the freezer from the wall outlet.
- Wait 60 seconds.
- Plug the freezer back in.
- Confirm the display and interior light respond when you open the door.
- Let the freezer run several hours before judging temperature changes.
If the control panel is locked
Some FFU14F5HWN units can lock the temperature controls to prevent accidental changes.
- Press and hold Alarm Reset for 3 seconds to toggle the control lock.
- Watch the display for a lock/unlock indication.
- After unlocking, adjust temperature using the UP (colder) or DOWN (warmer) buttons.
For the exact button sequence and display behavior, follow the FFU14F5HWN owner's manual.
What “reset” does (and does not) do
A reset helps when the freezer is running but acting “stuck” (odd display behavior, alarms that will not clear, or temperature not responding to changes). It does not fix a failed part.
| Symptom after reset | Most likely area to check | Common next step |
|---|---|---|
| Alarm keeps sounding but temps are normal | Door not sealing or door left open | Check gasket contact and door closure |
| “HI TEMP” or warm temps continue | Airflow/defrost/cooling system | Verify vents clear; listen for fan |
| Display shows an “E” code | Electronic control issue | Use Frigidaire deluxe electronic control module freezer error codes |
Why it matters
Resetting correctly prevents unnecessary part replacement and gives the electronic temperature control time to stabilize between changes. If the freezer is not level, the door may not seal well, which can cause frost and temperature problems even after a reset.
