Common Sensor Error Codes

  • "SN-2" refers to a non-functional temperature sensor.
  • "SN-1" refers to a non-functional Hi Limit sensor.
  • Three dashed lines ("watchdog") is almost always corrected by replacing the temperature sensor.
  • Rapidly changing temperature or wildly inaccurate displays are almost always fixed by replacing the temperature sensor.

The Hi Limit Sensor replacement is much less common than replacing the temperature sensor, but it does happen.
