• "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.
