What Our Customers Say
"I am so happy with the services provided by TruePro Home Services! I have a very old oven that I truly believed would need to be replaced. But, Yury came on time, diagnosed the issues, and had the parts with him to do the repair the same day. My oven is now in perfect working order. Highly recommend!"

"Our LG Front Loading washer wasn't draining. I contacted Simon the next day. He had the part on his truck and came by within 30 minutes, and had it up and running super fast! Thank you Simon for your punctuality, honesty and great value. See you next time!"

"Wonderful and top notched care! They were able to meet my same day expectation to get a washer and dryer hooked up in a new house. He was attentive, thoughtful and explained it all as well. I would highly recommend their service!"

What Error Code 5E Means
Error code 5E signals that the fridge compartment defrost sensor is malfunctioning. This sensor tracks evaporator temperature on the fresh food side during defrost cycles. A failed sensor causes incomplete defrosting, frost buildup behind the rear panel of the fridge section, and reduced cooling. Newer Samsung displays show this as 5C.
Common Causes
Failed fridge defrost thermistor
The thermistor mounted on the fridge-side evaporator has an open or short circuit. Normal wear causes failure after 5-10 years of service.
Frost buildup insulating the sensor
A previous defrost problem allowed frost to build around the sensor. The ice layer prevents accurate temperature readings.
Wire break near the evaporator
The sensor wire runs through a cold zone where ice expansion and thermal cycling crack the insulation and snap the conductor.
Connector corrosion
Moisture from condensation corrodes the pins at the sensor connector, causing intermittent or complete signal loss.
How to Fix It
- 1
Power reset the unit
Unplug the refrigerator for 60 seconds. Plug it back in. Monitor for 10 minutes. If the 5E code does not reappear, the fault was a temporary communication error.
Always unplug before accessing internal components.
- 2
Remove the fridge rear panel
Take out all food and shelves from the fresh food compartment. Remove the rear panel by unscrewing the Phillips-head screws around its perimeter (usually 4-6 screws). Pull the panel forward carefully. Note any frost or ice behind the panel.
- 3
Manually defrost if ice is present
If the evaporator area behind the panel has frost buildup, leave the fridge unplugged with the door open for 3-4 hours. Place towels on each shelf to absorb water. A room-temperature fan aimed into the compartment speeds up defrosting without risking component damage.
- 4
Test the fridge defrost sensor
Locate the defrost sensor clipped to the fridge evaporator tubing. Disconnect its two-wire plug. Set a multimeter to the 20k-ohm range. At room temperature (77 degrees F), expect a reading around 5 kOhms. OL or 0 ohms confirms the sensor is bad. Order the correct Samsung replacement part for your model (check the data plate inside the fridge door).
Verify the unit is unplugged before disconnecting the sensor.
- 5
Replace the sensor and test
Unclip the bad sensor. Connect the new sensor to the harness and clip it onto the same evaporator tube. Reinstall the rear panel with all screws. Replace shelves and food. Plug in the fridge. Run a forced defrost by pressing Energy Saver and Fridge simultaneously for 8 seconds (model-dependent). Confirm the defrost cycle completes and the 5E code stays off.
When to Call a Professional
Call a technician if the code returns after sensor replacement, if you see damage to the evaporator coils, or if the defrost heater is not producing heat. TruePro's $59 diagnostic fee is credited toward your repair. All work carries a 90-day warranty on parts and labor. Service covers LA County, Orange County, and Ventura County with same-day appointments often available. Call 877-378-3111. Use code NEW15 for 15% off labor as a first-time customer.
Estimated Repair Cost
| Option | Estimated Cost |
|---|---|
| DIY (parts only) | $15 - $45 |
| Professional repair | $175 - $350 |
Sensor replacement is at the lower end. If the defrost heater or control board also needs work, costs increase toward $350-$450.
