Samsung Oven Error Code LE — Low Voltage Error
What this means
The LE error code indicates the oven's control board has detected voltage below the acceptable operating range. Samsung electric ovens require a 240V supply (in the US), and significant voltage drops can prevent the heating elements from operating properly. This can be caused by a loose connection in the junction box, a tripped breaker providing only half voltage, or a problem with the home's electrical supply.
Alternate codes: -LE-
Step-by-step fix
3 stepsCheck the circuit breaker
Electric ovens use a double-pole 240V breaker. Check your electrical panel and ensure both poles of the breaker are fully in the ON position. Turn the breaker off and back on.
A double-pole breaker can trip one leg while the other stays on, supplying only 120V instead of 240V.
Test the outlet voltage
Using a multimeter, test the voltage at the oven's power outlet or junction box. You should read 240V between the two hot leads. Readings significantly below 220V may cause the LE error.
If you are uncomfortable testing high-voltage circuits, call an electrician.
Check the power cord connections
Unplug the oven (or turn off the breaker) and inspect the power cord connections at both the outlet and the junction box on the back of the oven. Tighten any loose terminal screws.
A loose wire terminal can cause voltage drop under load.
When to call a professional
If the voltage at the outlet is correct but the error persists, the oven's internal wiring or power supply board may be faulty. Call an appliance technician. If the house wiring is providing low voltage, call an electrician.
