EF3 explained
“Max Timeout Timer” is the wording for current dryers in sheet 137559700C (1302 edition) and sheet 137265000B (1202 edition).
Items the sheets list beside it
Exhaust that is blocked
The Exhaust Control Thermistor
The Inlet Control Thermistor
The Contact Sensor
The electronic control board, if defective
The cause could be any one, and sorting through them calls for a technician. Until then, stop the dryer and keep it unplugged.
Codes to compare
The vent blocked code is EF1; the key stuck code is EF8.
