Samsung Oven LE — Low DC Voltage / Low Line Voltage

Samsung Oven · Error code LE

What LE Means

The main control board is seeing low DC voltage (typically under 9 VDC on internal rails), or low incoming line voltage from the house supply.

Symptoms

  • LE displayed at power-up or during cook
  • Oven won't start or randomly shuts off
  • Display dimmer than normal
  • Clock loses time

Common Causes

1
Low incoming line voltage

Brownout or undersized circuit dropping voltage under load.

2
Loose neutral or hot at terminal block

Connection at the range/oven not fully tight.

3
Failed low-voltage power supply on main PCB

Onboard 5/12 VDC rail collapsed.

4
Long/undersized branch circuit wire

Voltage drop under load exceeds spec.

How to Fix It

  1. Cut power at the breaker.
  2. Inspect and retighten the terminal block / pigtail connections on the range or wall oven.
  3. Measure incoming voltage at the terminal block under load — both legs should be ~120V to ground, ~240V leg-to-leg.
  4. If incoming voltage is low, the issue is house wiring or utility supply (call an electrician).
  5. If incoming voltage is good, the low-voltage section of the main control board has failed — replace the main PCB.
