Hi my name is Robert....
When the red led is ON the high limit sensor is tripped. What you can do for testing ONLY is bypass the sensor and see if the code goes away, if the code goes away then I suspect you have a faulty sensor. The code should only be coming on when the sensor trips or the light is ON. IF the code does not go away when you bypass the sensor then you could have a circuit board issue. Click HERE for some info on that box and it will show the wiring and how to bypass, YOU CAN NOT leave it hooked with it bypassed it is a safety issue... Hope this helps some.... Robert
