Damaged insulation of the wire unit of the temperature sensor (reference 1 & 2image "Lamp temperature sensor connection"), which measures the temperature in the channel of the air outlet of the Lamp House. When disconnecting the wire unit of the temperature sensor from the Signal Backplane (reference 3 image "Lamp temperature sensor connection") the error code is changed to “lamp - temperature sensor open”.

1. Repair the insulation of the wire unit using shrink sleeve.

2. If not repairable, replace the whole wire unit and temperature sensor.
