Matrice 4T Complete Repair Guide: Common Issues and Parts
The Matrice 4T is a flagship enterprise drone used in thermal inspection, public safety, and industrial operations. Its multi-sensor payload — combining a wide camera, zoom camera, and thermal camera — makes it one of the most capable drones in its class. This guide covers the most common repair scenarios and the correct replacement parts for each.
Gimbal Motor Issues
Symptom: Gimbal drifts or shakes on one axis / gimbal motor overloaded error
The Matrice 4T gimbal uses three dedicated brushless motors for Yaw, Pitch, and Roll stabilization. Each motor is a separate replaceable component.
- Gimbal Yaw (Y-Axis) Motor Compatible with Matrice 4T — SKU AT00037
- Gimbal Pitch (P-Axis) Motor Compatible with Matrice 4T — SKU AT00039
- Gimbal Roll (R-Axis) Motor Compatible with Matrice 4T — SKU AT00041

Gimbal Signal Cable Issues
Symptom: Black screen or no video from one camera / intermittent video dropout
The gimbal signal cable carries video and control data between the camera payload and the aircraft. A damaged cable causes image dropout or complete loss of feed from one or more cameras.
- Gimbal Camera Signal Coaxial Cable Test Board Compatible with Matrice 4T — SKU AT00043 (use to diagnose before replacing cable)
Payload Housing Issues
Symptom: Cracked or broken payload housing after crash
The payload housing protects internal components from environmental damage. Replace the damaged piece to restore protection.
- Payload Front Faceplate Housing Shell Compatible with Matrice 4T — SKU AT00035
- Payload Rear Enclosure Back Cover Compatible with Matrice 4T — SKU AT00036

Arm and Motor Issues
Symptom: Motor error code / one arm motor not spinning / drone unstable on takeoff
The Matrice 4T uses high-torque brushless arm motors. A failed motor causes flight instability and motor error codes in DJI Pilot 2.
- High-Torque Brushless Motor Compatible with Matrice 4T / 4E — SKU m4t-motor
Diagnostic Tools
Before ordering replacement parts, use diagnostic tools to confirm which component has failed:
- Gimbal Camera Signal Coaxial Cable Test Board — SKU AT00043. Tests signal cable continuity across all camera channels.
Post-Repair Calibration
After any repair on the Matrice 4T, perform the following calibrations before returning to service:
- Gimbal auto-calibration (in DJI Pilot 2)
- IMU calibration (see our IMU calibration guide)
- Compass calibration outdoors (see our compass calibration guide)
- Full payload calibration
