Summit Refrigerator E1 — What It Means & How to Fix It
Also shown as E2 on some models.
E1 or E2 on a Summit frost-free refrigerator-freezer means the air temperature sensor has failed.
What this code means
Summit's manual states that "E1" or "E2" indicates that the air temperature sensor has failed. The control uses that sensor to decide when to run the compressor, so it can no longer hold the cabinet at the set temperature reliably. The manual offers no owner repair for the sensor codes.
Summit's user manual for the FFRF24SS, FFRF24S1S, LFD24S1, BRF241FD, FFRF3070B and FFRF3075W lists this code in its troubleshooting table. Summit sells many different cabinets, so confirm the code in the manual for the model number on your rating label.
Most likely causes
| Cause | How likely | DIY-fixable? |
|---|---|---|
| Failed air temperature sensor | Common | No — technician job |
| Sensor wiring fault inside the cabinet | Occasional | No — technician job |
What you can try yourself
- Note the code and the model and serial number from the label inside the cabinet.
- Keep the door closed as much as possible and move perishable food to another refrigerator if the cabinet warms up.
- Contact Summit or an authorized servicer to have the sensor diagnosed.
Seeing the symptom rather than the code? Refrigerator not cooling: checks that apply across brands.
When to call a technician
- E1 or E2 is on the display — the sensor needs professional diagnosis.
- The cabinet is warming up or freezing food.
- The alarm sounds and the temperature display flashes.
Typical professional repair cost: A sensor replacement by a refrigeration technician is typically $150–$300 including the visit.

Is my Summit fridge safe to use with E1 showing?
Its temperature control cannot be trusted while the air sensor is faulty. Check the food with a separate thermometer and arrange service.
