Samsung Range Error Code LE

LE stands for Low voltage Error on a Samsung range. It means the internal DC 12V power supply has dropped below 9V, which is too low for the control electronics to operate reliably. The most common causes are a defective main PCB or a problem with the wiring harness connected to it.

No, you should not continue using the range while the LE error is active. A voltage supply problem can cause unpredictable control board behavior, which may affect heating elements, temperature regulation, or other safety systems. The range should remain off until the fault is diagnosed and repaired.

Repair costs vary depending on the cause. If only a wiring connector needs to be cleaned or reseated, costs may be limited to a service call fee, typically in the range of $75 to $150. If the main PCB requires replacement, parts and labor combined can range from $200 to $450 or more depending on the specific model and local labor rates.

A knowledgeable DIYer can inspect the wiring harnesses and connectors for corrosion, loose pins, or visible damage, which may resolve the error without parts. However, if the fault lies within the main PCB itself, board replacement is required and working near high-voltage components inside a range carries serious safety risks. Professional service is recommended if wiring inspection does not identify an obvious fault.

A power reset, such as unplugging the unit for a few minutes, may temporarily clear the LE error if the voltage drop was caused by a momentary anomaly. However, if the underlying cause is a failing PCB or a wiring defect, the error will return during normal operation. A reset is not a fix and should only be used as a first step in diagnosing the issue.
