You open the refrigerator, glance at the panel, and instead of a temperature you see E1. Maybe it’s beeping. Maybe the milk still feels cold, maybe it doesn’t. Either way, it’s one of those moments that makes you stop and wonder whether you’re about to lose a fridge full of groceries.
E1 doesn’t automatically mean your refrigerator is finished. But it does mean the control is telling you something about how it reads temperature — and on Frigidaire, what E1 means depends on which appliance and which model you own. Get that part right, and you won’t chase the wrong problem.
In this guide, we’ll walk you through what Frigidaire’s own guides say E1 means, why the code isn’t the same on every model, the alerts Frigidaire tells you to clear yourself, the free checks that come first, what a technician looks at next — and when it’s time for Frigidaire refrigerator repair.
What E1 Means on a Frigidaire Refrigerator
In the Frigidaire refrigerator guides that list E1 at all, it points to a temperature sensor in the refrigerator (fresh food) compartment:
- The use and care guide for the bottom-freezer FFBN1721TV lists E1 as “Temperature sensor failure of fresh food compartment,” with E2 for the freezer sensor.
- The guide for the compact bottom-freezer FRBG1224AV lists E1 as “Temperature sensor of refrigerator compartment” — and says to call service to report error codes.
A temperature sensor (often called a thermistor) is a small electronic thermometer. It tells the control board how cold each section is, and the board decides when to run the cooling system. When a sensor reads wrong — or stops reading — the board can’t regulate temperature with the accuracy it was built for. That’s why E1 deserves attention even if the fridge still feels cold.
One more place you might see E1: Frigidaire’s wine cooler guide says a code such as “E1,” “L” or “H” can appear instead of the temperature when the temperature probe is out of order, with continuous beeping. The unit keeps running its compressor and fans to protect your wine, but Frigidaire recommends having it serviced as soon as possible.
Why E1 Needs Your Exact Model Number
Frigidaire uses different control boards, displays and alarm systems across its lines, and not every model shows E1.
Many popular Frigidaire refrigerators — including the Gallery side-by-side FGHS2631PF, the FFHS2622MS side-by-side, the FGHB2868TF and the FRFS2823AS — don’t list an E1 code in their use and care guides at all. On those models, Frigidaire describes alarms instead: HI or a flashing temperature for a high-temperature condition, a power failure light, and a door ajar alert. Their guides say that if the digital temperature displays flash or show an error, the electronic control has detected a performance problem, and a service representative can interpret the message.
So if you’re seeing “E1” on a model whose guide never mentions it, write down exactly what the display shows — letters, numbers, any lights — and the model number from the label inside the fresh food compartment. That’s what a technician needs first.
When we get an E1 call, three things come first:
- the exact model number and the type of control panel;
- whether any other indicator or alarm shows alongside E1;
- which section is struggling — refrigerator or freezer — because the diagnostic path is different.
That order prevents wasted time and parts that don’t solve the real problem.
Step 1: Clear the Alert the Frigidaire Way
Before anyone treats a code as a repair, Frigidaire’s support guidance starts with the alerts an owner can clear. Depending on your model, it suggests:
- Press CLEAR ALERTS (or Alert Reset, or Alarm Reset — the name varies by model). On the FRFS2823AS, for example, Clear Alerts resets any active door open, high temp or power outage alarm.
- Reset the unit by unplugging it for 30 seconds and plugging it back in. If you can’t reach the plug, Frigidaire says you can flip the breaker — but that resets everything on the same circuit.
- Watch and wait. Frigidaire’s guides say to allow 24 hours for temperature to stabilize after a change.
If the display returns to normal and stays that way, you may have had a temporary event. If E1 comes right back, a reset won’t fix it. On models that define E1, it’s a sensor fault, and the guide says to call service.
Step 2: Rule Out the Everyday Causes of Temperature Alarms
E1 itself is a sensor code. But on many Frigidaire models, the first thing owners actually see is a temperature alarm — and Frigidaire is clear about what usually triggers one. Its support article on the HI alarm lists a door left open for an extended time, temperature settings that were changed, and a door that isn’t sealing well.
These checks cost nothing, and they matter even if your display says E1: a warm fridge and a sensor fault can look alike from the kitchen.
1) Check the doors and the seal
Frigidaire says to double-check the gasket — the rubber seal around the door — for a good seal. Make sure nothing inside is keeping a door from closing: Frigidaire’s troubleshooting tables point to food or packaging blocking the doorway, and to a refrigerator that isn’t level.
2) Verify the settings
Frigidaire’s recommended settings for a refrigerator installed in a kitchen are 37°F for the fresh food compartment and 0°F for the freezer. If someone adjusted them, set them back and give the unit 24 hours before changing anything else.
3) Think about the last day or two
A long door-open, a power outage or a big load of warm groceries can push temperatures up for a while. Frigidaire notes that a power outage or surge can also trigger a high-temp alarm. If the temperatures recover and the alert doesn’t return, you’re likely fine.
4) Use a separate thermometer
Some Frigidaire guides note that a two-digit temperature display is for reference only. To know the real temperature, put an appliance thermometer in the compartment and read it after a few hours. The FDA advises keeping a refrigerator at or below 40°F.
Corrected these and the display is back to normal? Good. If E1 comes back anyway, the cause isn’t the kitchen — it’s inside the temperature control system.
Step 3: When E1 Returns — What a Technician Checks Next
If E1 returns after the alerts are cleared and the doors and settings check out, it’s time for component-level diagnosis. Safety first: many current Frigidaire refrigerators use a flammable refrigerant, and their guides say repairs are to be done only by trained service personnel. Don’t remove panels or covers to get at sensors or wiring yourself.
A technician focuses on the parts that measure, move and interpret temperature:
1) The temperature sensor
The sensor is the control’s feedback. If it reads inaccurately or intermittently, the board can’t regulate cooling, and the code returns. On models whose guides define E1, this is the first suspect.
2) The sensor wiring
A wiring harness can be pinched, loosened or corroded — especially after a unit has been moved, leveled or serviced. Intermittent wiring faults often make a code clear for a while and then come back.
3) Airflow and the evaporator fan
Cold air has to circulate. If the evaporator fan — the fan that moves cold air through the unit — isn’t working right, temperatures drift even when the sealed system is healthy. Frigidaire’s guides also warn not to block the air ports inside.
4) The control board
Control boards do fail, but they’re the last step, not the first. A careful diagnosis tests the sensor and its wiring with a meter before a board is ever replaced — that’s what separates a clean repair from trial-and-error part swapping.
E1, E2, HI, PF: Why You See Several Codes Mentioned Together
Owners often find E1, E2 and other codes listed side by side, because Frigidaire platforms don’t all display alerts the same way:
| What you see | What Frigidaire’s guides say |
|---|---|
| E1 | On models that list it: fresh food (refrigerator) temperature sensor |
| E2 | On models that list it: freezer temperature sensor |
| HI, or a blinking temperature | A high-temperature condition in the refrigerator or freezer |
| PF, or a power failure light | A power outage or power surge; it can also trigger a high-temp alarm |
| Flashing displays or an error on models without codes | The control has detected a performance problem; call service |
The fix depends on which one your model shows — another reason the model number comes first.
Frigidaire Models We See With Temperature Alerts
Across the Atlanta area, temperature control and alert calls come from all over the Frigidaire line, including:
- Gallery and Professional series refrigerators;
- side-by-sides such as the FGHS2631PF and FFHS2622MS;
- bottom-freezer and French-door models such as the FGHB2868TF and FRFS2823AS;
- bottom-freezer models whose guides list E1, such as the FFBN1721TV and FRBG1224AV.
Whatever the model, when the display shows a code, it deserves a prompt, correct diagnosis — to protect your food and to keep the compressor from working harder than it should.
When to Call for Repair
Book a visit if:
- E1 returns after you clear the alerts;
- refrigerator or freezer temperatures stay unstable;
- the unit runs constantly or struggles to recover after normal door use;
- a high-temperature alarm keeps coming back;
- you’ve checked the doors, seal and settings, and the code continues.
Frigidaire’s own guides send owners to service at exactly this point: when a code or a flashing display remains, a service representative interprets it.
Check the Warranty First
Frigidaire’s use and care guides describe a one-year limited warranty from the original date of purchase, provided by Electrolux, and say warranty service must be obtained by contacting Electrolux. If your refrigerator is new, check your warranty document or contact Frigidaire before booking any repair; this page doesn’t tell you whether your unit is covered.
The Bottom Line
On the Frigidaire refrigerators that use it, E1 points to the fresh food temperature sensor. On many other models, you’ll see HI, PF or a flashing display instead. Either way, the right first steps are the same: clear the alert, check the doors and seal, set 37°F and 0°F, and give it 24 hours. If the code returns, the next step isn’t another reset — it’s a diagnosis of the sensor, its wiring, the airflow and, last, the control board.
Frequently Asked Questions
What does E1 mean on a Frigidaire refrigerator?
On the Frigidaire refrigerators whose guides list it — such as the FFBN1721TV and FRBG1224AV — E1 means a problem with the temperature sensor in the fresh food compartment. Many other Frigidaire models don’t use E1 at all, so check your use and care guide by model number.
How do I clear a Frigidaire error alert?
Depending on the model, press CLEAR ALERTS (or Alert Reset), or reset the unit by unplugging it for 30 seconds. Frigidaire notes that flipping the breaker also works but resets everything on that circuit. If E1 returns after a reset, the code points to a fault, not a one-time event.
What causes high-temperature alarms on a Frigidaire?
Frigidaire lists a door left open for a long time, changed temperature settings, and a poor door seal. A power outage or surge can trigger one too. Check the gasket, make sure nothing blocks the door, and return the settings to 37°F and 0°F.
What are the recommended Frigidaire temperature settings?
Frigidaire recommends 37°F for the refrigerator and 0°F for the freezer for a product installed in a kitchen. After any change, allow 24 hours for the temperature to stabilize before adjusting again.
What does PF mean on a Frigidaire refrigerator?
PF, or a power failure light, indicates a power outage or power surge. Frigidaire says it can also lead to a high-temperature alarm. Acknowledge it with the alarm or alert button, then watch the temperatures recover.
Can I keep using my refrigerator while E1 is showing?
For a short time, with care. Check the real temperature with an appliance thermometer — the FDA advises 40°F or below for the refrigerator — and move perishables if it’s climbing. Since E1 points to a sensor, the control may not be regulating accurately, so book a diagnosis rather than waiting it out.
Get Stable Temperatures Back
If E1 keeps coming back, or your Frigidaire won’t hold temperature after the checks above, it’s time for a technician who can test the sensor, wiring and control properly.
