How to fix E-28
- Cut power at the breaker for 3 minutes, then restore it.
- If E-28 returns, stop baking and call Samsung or a qualified technician. They would test the sensor and check the wiring behind the oven for a pinch or burn. Do not remove the sensor or open the oven back yourself.
When to stop and call a repairer
Cut power at the breaker before any service work; testing the sensor is for a technician.

How to check the error log
Samsung ovens do not have a user-accessible error log. The code stays on the display until you fix the cause or cut power at the breaker for 3 minutes; if it returns after a reset, treat it as real.
Clear the log after a repair so you can tell whether the fault has really gone.
Beyond the fix
Tips and tricks
- The same technician video covers E-27 and E-28 together and ties both to the oven temperature sensor. A resistance check on the unplugged sensor is how it is confirmed, which is work for a qualified technician.technician video
- Compare the display against a separate oven thermometer. A mismatch supports a sensor fault.technician video
Common mistakes
- Treating E-27 and E-28 as different parts. One video groups them as the same sensor circuit.

Questions
What does E-28 mean on the Samsung range and wall oven?
Oven temperature sensor short circuit (resistance too low). The board reads the oven temperature sensor as a short circuit: a shorted probe or a pinched harness are the plausible causes. The Samsung pages we read give no resistance limits.
Can I fix E-28 myself?
DIY difficulty: hard. Cut power at the breaker for 3 minutes, then restore it. If E-28 returns, stop baking and call Samsung or a qualified technician. They would test the sensor and check the wiring behind the oven for a pinch or burn. Do not remove the sensor or open the oven back yourself.

E-28 during startup or during use?
Samsung range and wall ovens report E-28 any. That timing is a useful clue when narrowing the cause.
Can I keep using the machine with E-28 showing?
Usually you can finish the drink you are making, but do not ignore it — the underlying fault rarely heals itself. Work through the cheap checks first.
Will E-28 clear on its own?
Rarely. A reset or power cycle is worth one try, but E-28 with a "hard" difficulty rating almost always means a failed component that has to be replaced.
How long does the repair take?
This one is a bench repair for most owners — the teardown, test and reassembly are the bulk of the work, not the part itself.
