My Innovate LC-2 keeps blinking and never finishes warming up the sensor. How do I troubleshoot it?

Try this sequence: (1) power the LC-2 on without the sensor connected for 10–30 seconds, (2) power off and connect the sensor, (3) power on and let it heat up and auto-calibrate. Also check that all pins of the sensor-cable connector are straight. If the warm-up still stops (e.g. LogWorks shows warm-up stuck at ~20%) with a known-good sensor and cable, the controller is faulty and should be returned for replacement.
