How to fix E-27
- Cut power at the breaker for 3 minutes, then restore it.
- If E-27 returns, stop baking and call Samsung or a qualified technician. They would test the sensor probe, its plug and its wiring against the sensor's expected reading. Do not unscrew 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
- If the display temperature seems off, compare it with a separate oven thermometer. One repairer found a Samsung oven showing one temperature while a thermometer showed another, which pointed to the sensor.technician video
- A technician explains the sensor is a two-wire probe near the heating elements, tested by resistance, and that resistance should drop as the tip warms. The test needs the range unplugged, so leave it to a qualified technician.technician video
Common mistakes
- Replacing a sensor without checking the connection. One repairer found the sensor lead too short to reach its plug, which needed rear-panel access.

Questions
What does E-27 mean on the Samsung range and wall oven?
Oven temperature sensor open circuit (resistance too high). The board reads the oven temperature sensor as an open circuit: a loose plug, a broken wire or a failed probe are the plausible causes. The Samsung pages we read give no resistance limits. One technician video describes the sensor as an NTC probe that reads about 1,000 ohms at 25 C.
Can I fix E-27 myself?
DIY difficulty: hard. Cut power at the breaker for 3 minutes, then restore it. If E-27 returns, stop baking and call Samsung or a qualified technician. They would test the sensor probe, its plug and its wiring against the sensor's expected reading. Do not unscrew the sensor or open the oven back yourself.

When does E-27 typically show up?
Samsung range and wall ovens report E-27 any. That timing is a useful clue when narrowing the cause.
Can I keep using the machine with E-27 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-27 clear on its own?
Rarely. A reset or power cycle is worth one try, but E-27 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.
