Associated CAS:

R WSHLD HEAT FAIL
(Caution)

The Right Windshield Sensor has been detected Open circuit (sensor resistance≥ 600 ±60 ohms).

• Right Window Temperature Sensor (HR7)
• Associated Wiring
• Right Windshield Temperature Controller (R WTC) (A165)

Advisory Wire/Service Bulletin:

• AW700-30-0463 - No Fault Found (NFF) initiative - Windshield Temperature Controller (WTC)
• Windshield Troubleshooting Report to help with windshield temperature controller NFF

Full Throttle Blog/Forum Articles/Infoservice/Newsletter: None

Flight Operation Notifications Manual (FONM): None

NOTES:

• There are three temperature sensors installed between the plies of each windshield and side window, one for control and monitoring and two spares (depending on model).

1. Remove all connectors from the right WTC. Inspect connectors and pins for damage/defects.

   1. If no defects or damage is found, reconnect the WTC connectors and continue with next step.
   2. If defects or damage is found, repair/rectify as required.

2. Perform wiring checks between Right Windshield temperature sensor and R WTC.

   1. If wiring checks are not good, repair defective wiring as required and do close out.
   2. If wiring checks are good, continue with next step.

3. Measure the temperature sensor resistance (refer to Windshield and Side Window Temperature Sensor Resistance Chart).

   1. If resistance is within range, go to step 5.
   2. If resistance is out of range, continue with next step.

4. Connect spare temperature sensor on right windshield (HR7 S2 or S3).

   1. If system checks are good, do close out.
   2. If fault remains, continue with next step.

5. Interchange the right WTC with the left WTC to confirm faulty unit

   1. If system checks are good, do close out.
   2. If fault remains, continue with next step.

6. Replace Right Windshield.
7. Do close out.
