This message indicates that the chamber thermistor detects a possible short circuit, which may cause an abnormal reading of the chamber temperature and affect the normal operation of the device.
Check the wiring: carefully check the thermal connection of the chamber to see if there is damage or short circuit. If it is damaged, replace it.
Replace the sensor: If the problem persists after troubleshooting, you may need to replace the chamber thermal sensor to restore normal function.
Check the cables to the chamber thermal sensor and ensure that the connection is secure and not damaged.
If the thermal cable is damaged, replace it and reconnect it.
If the problem persists, consider replacing the chamber thermal sensor.
Restart the device and check whether the chamber temperature can be read.
