How to fix it

  1. Cut power at the breaker.
  2. Unplug the temperature sensor and measure resistance — far below 1080 ohms confirms a short.
  3. Replace the sensor if shorted.
  4. If a new sensor still reads short at the PCB, inspect the harness for damage where it routes through the cavity wall.

Why it happens

Typical signs: E-28 at startup or when bake is selected · Oven refuses to heat · May alternate with E-27

  • Shorted RTD sensor Sensor element shorted internally.
  • Pinched harness shorting to chassis Wire to sensor grounded.
  • Moisture bridging sensor connector Water/cleaning fluid in the plug.
