Samsung Refrigerators Error Code E7 – Freezer Temperature Probe

When your Samsung refrigerator suddenly flashes Error Code E7, it’s your appliance’s way of telling you there’s an issue with the freezer temperature probe. On RS21, RS55, and RS59 models, this sensor monitors freezer conditions and sends data to the control board. If it fails, your freezer may struggle to maintain the correct temperature, putting your stored food at risk.

This guide walks you through what the Error Code E7 means, how to troubleshoot it yourself, and when it’s time to call a professional appliance repair.

What Does Error Code E7 Mean?

 

The Error Code E7 signals a problem with the freezer temperature sensor (probe). Common causes include:

• Sensor failure (open or short circuit)
• Damaged wiring between the probe and the control board
• Faulty main control board
• Corrosion or moisture damage in the sensor’s connection points

Sometimes, the issue is temporary and can be cleared with a reset. Other times, parts need to be replaced.

Safety First

Before starting any repair:

1. Unplug the refrigerator or turn off the breaker to cut power.
2. Wear insulated gloves to protect from sharp metal edges.
3. Move perishable food to another cold storage option.

Step-by-Step Troubleshooting for Error Code E7

1. Reset the Refrigerator

• Disconnect power for 5–10 minutes.
• Reconnect and check if the error clears.
• If the E7 code reappears, move on to the next step.

2. Inspect the Freezer Temperature Probe

On RS21, RS55, and RS59 models, the probe is usually located behind the rear freezer panel.

Steps:

• Remove freezer drawers and shelves.
• Unscrew the rear panel inside the freezer.
• Look for the small cylindrical probe attached to the evaporator.
• Check for visible damage, frost buildup, or loose connections.

3. Test the Sensor

• Use a multimeter to measure resistance at the sensor’s terminals.
• At room temperature (20°C/68°F), most Samsung temperature probes should read about 5–10 kΩ.
• If the reading is outside the expected range, replace the probe.

4. Check Wiring

• Trace the wires from the probe to the control board.
• Look for pinched, frayed, or corroded wires.
• If damaged, repair or replace the wiring harness.

5. Consider the Control Board

If the probe and wiring are fine, the issue may lie in the control board itself. Replacing the board requires handling sensitive electronics—this is where calling an express fridge repair service is wise.
