What does Samsung Oven E-28 Error Code - Causes & Fix mean?

E-28 means the oven temperature sensor circuit reads shorted. Test the sensor and replace it if it is far off 1080 ohms.

How do I fix Samsung Oven E-28 Error Code - Causes & Fix?

Follow the step-by-step diagnosis below. The most likely fix is identified by checking power, sensor resistance, and control-board signals in order — using a multimeter and the part numbers documented in the parts reference table.

Can I keep running the equipment with 28 active?

Generally no. Faults on Appliance units are emitted when a sensor, safety, or control circuit is outside its operating envelope. Running through an active fault risks compressor, heater, or control-board damage. Diagnose and clear the fault first.

What part is most commonly replaced for Samsung Oven E-28 Error Code - Causes & Fix?

The most frequently replaced parts for Samsung Oven E-28 Error Code - Causes & Fix are listed in the Parts Reference section of this guide with OEM part numbers and typical price ranges. Check the table for direct replacements.

Is Samsung Oven E-28 Error Code - Causes & Fix a DIY repair or do I need a technician?

Sensor swaps, fan motor replacements, and condenser cleaning are typical DIY-level repairs. Anything involving refrigerant, gas, or high-voltage (>240V) work requires a licensed technician for both safety and code-compliance reasons.

Samsung Oven E-28 Error Code — What It Means

E-28 is a short circuit fault on the Samsung oven temperature sensor. The board saw a resistance far below normal, which it treats as a shorted probe or harness.

A good sensor reads about 1080 ohms at room temperature. A reading near zero, or a probe sheath shorting against the cavity metal, drives the board to post E-28 and stop the cook.

Jump to Fix

Common Causes

Shorted temperature sensor The probe element has failed low and reads close to zero ohms.
Pinched harness lead A wire crushed against the chassis shorts the two sensor leads together.
Melted sensor insulation Heat near the cavity has melted the lead jacket and bridged the conductors.
Probe shorting to cavity A cracked sheath lets the sensor element touch grounded metal.
Control board input fault Less often the board sensing circuit misreads a good sensor as shorted.

Step-by-Step Fix

Cut power at the breaker for one minute, restore it, and watch for E-28 to return.
Pull the range and remove the back panel to reach the sensor harness.
Unplug the temperature sensor connector and inspect the leads for pinch or melt damage.
Set a multimeter to ohms and measure the sensor. Expect about 1080 ohms at room temperature.
Replace the sensor if it reads near zero or far below spec.
Check that the harness is not crushed against the chassis and reroute any pinched section.
If the sensor and wiring test good, have the control board input checked.

Parts Often Needed

Part	Notes
Samsung oven temperature sensor (probe)	Amazon \| OEM part DG32-00002B fits many Samsung ranges. Verify against your model number.
Oven sensor wire harness	Amazon \| Replace when a lead is pinched or melted rather than the probe.
Samsung range main control board	Amazon \| Last resort after the sensor and harness test good.

When to Call a Pro

A short that returns after a new sensor often hides in the harness or the board. If you cannot find the pinched lead, a tech can trace the circuit and confirm whether the board sensing input has failed.
