TEMPERATURE SENSOR ERROR
Cause
Temperature Sensor Error
Solution
Check connections at theremistor and main board.
Also check thermistor for proper resistance.
DETAILS BELOW:
Is connector to thermistor disconnected or corroded?
With power on, does tE error still display when shaking thermistor connection?
If so, reconnect or repair connector.
The Main board should be outputting 5 VDC to the thermistor wires measured with thermistor disconnected, if not replace main board, if yes, check thermistor resistance.
