What does it mean if I have a flashing red light on the High Temperature Sensor?

• If slow flashing (1 flash per second): Low DC power.
• If fast flashing (2-3 flashes per second): There’s a break in thermistor wire.

To have this flashing cleared, you will need to take your unit into your local service center. This is not something that is serviceable by the consumer, for safety and liability reasons.
