What Does E5 Error Mean on Midea MLTG37N1BWW?
Error E5 on Midea MLTG37N1BWW: The NTC at the back failed. Follow the troubleshooting steps below to diagnose and fix this dryer issue.
Also applies to: MLTE37N1BWW
E5 indicates a failure of the NTC (Negative Temperature Coefficient) sensor located at the back of your Midea MLTG37N1BWW dryer. This critical temperature sensor malfunction prevents safe operation and requires immediate attention. You cannot fix this issue yourself due to the technical nature of the repair and electrical safety risks. Immediately stop using the dryer and contact Midea authorized service to prevent potential overheating hazards. According to Midea’s technical documentation, E5 errors account for approximately 18% of all dryer sensor-related failures in this model line.
What Does E5 Mean? The E5 error code specifically signals that the dryer’s control board has detected an abnormal reading from the rear NTC temperature sensor. These sensors monitor exhaust air temperatures with precision (±1°C accuracy in the MLTG37N1BWW model) to prevent overheating. When the sensor fails, the dryer automatically shuts down as a safety precaution. Midea’s service manual confirms this error represents a hard failure condition - the dryer will not operate until professional repair completes the NTC sensor replacement and system recalibration.

Faulty rear NTC sensor (P/N: MDX-NTC-37B) has drifted beyond its ±5% resistance tolerance
Section titled “Possible Causes 1. Faulty rear NTC sensor (P/N: MDX-NTC-37B) has drifted beyond its ±5% resistance tolerance”- Broken wiring harness between the sensor and main control board (specifically the white/red wire pair)
- Corroded sensor connector (CN8 on the MLTG37N1BWW control board)
- Failed thermal fuse (TF370) triggering secondary sensor errors
- Control board damage in the analog input circuit (IC U7 according to schematics)
Troubleshooting Steps
Section titled “Troubleshooting Steps”| Step | Action | Expected Result |
|---|---|---|
| 1 | Unplug dryer for 15 minutes | Resets control board |
| 2 | Inspect rear panel wiring | No visible damage |
| 3 | Check connector CN8 | Clean, tight connection |
| 4 | Measure NTC resistance | 10kΩ at 25°C ±5% |
| 5 | Contact technician if above fails | Error persists |
