7E
Samsung Refrigerator
Severity: ModerateWhat Does This Error Mean?
The 7E error means the ice maker compartment temperature sensor (thermistor) has malfunctioned. The fridge cannot accurately read the temperature in that area. Ice maker function may be disrupted.
Affected Models
- RF28HMEDBSR
- RF28K9580SR
- RF23HTEDBSR
- RF25HMEDBSR
- Samsung French door models with in-door ice makers
Common Causes
- Ice maker room thermistor has failed (open or short circuit)
- Wiring connector to the thermistor is loose or corroded
- Ice or frost buildup has surrounded and damaged the sensor
- Main control board not correctly reading the sensor signal
- Physical damage to the sensor from ice ejection impact
How to Fix It
-
Turn off the ice maker and allow the compartment to defrost for 24 hours.
Frost surrounding the sensor can cause false readings — defrosting may resolve the error.
-
Power cycle the refrigerator — unplug for 5 minutes then restore power.
This resets the control board and clears any temporary sensor faults.
-
After restarting, turn the ice maker back on and monitor for 24 hours.
If the error does not return, a frost jam was likely the cause.
-
Check that the ice maker compartment door (in-door models) is closing fully.
A poorly sealed ice compartment door causes temperature swings that stress the sensor.
-
If the 7E error returns, the thermistor or its wiring harness needs professional replacement.
Do not attempt to continue running the ice maker without a functioning temperature sensor.
When to Call a Professional
A faulty thermistor is a straightforward replacement for a qualified technician. If left unrepaired, the fridge may over-cool or under-cool the ice maker compartment. Expect repair costs of $80–$160 for a thermistor replacement.
Frequently Asked Questions
Can a 7E error fix itself?
Occasionally — if frost was covering the sensor, defrosting the ice compartment may resolve it. But if the sensor itself has failed electrically, it will not fix itself. A sensor that has shorted or gone open circuit needs replacement.
How do I know if the sensor or the wiring is the problem?
A technician can use a multimeter to test the thermistor's resistance. A good thermistor shows around 5,000–10,000 ohms at typical freezer temperatures. An open circuit (infinite resistance) or short (zero resistance) confirms sensor failure.
Is the 7E error dangerous for food safety?
Not directly — the main fridge and freezer should continue cooling. But if the error is ignored for a long time, unregulated temperatures in the ice maker area can affect ice quality. Get it repaired within a few weeks.
