I have a whirlpool dryer model GEW9250 and I just start with a problem today I put it to work and it start normal but after 1 minute of working the machine stop working and it appears E2 in the screan thank you.
It is an indication of a shorted thermistor. Disconnect power to the dryer and check the resistance of the thermistor.
The thermistor (part #8577274) is located on the blower housing with red/white stripe and black wires and can be accessed by removing the lower front access panel. Remove the two hex-head screws attaching the bottom of the lower front access panel to the cabinet and pull the bottom out then down and move the panel away from the cabinet.
Disconnect one wire from the thermistor and use an ohmmeter, set to X1, to measure the resistance. Touch the ohmmeter test leads to the thermistor terminals and measure the resistance. The resistance reading at room temperature of a good thermistor is between 8.5 and 13.5 ohms; otherwise, replace the thermistor.
Remove the two screws mounting the thermistor to the blower housing then mount and secure the new thermistor in place. Connect the thermistor wires then slide the lower front access panel up back into position to the cabinet and secure its bottom with the two securing screws.
In case the measured thermistor resistance falls within the allowed range, measure the resistance between the disconnected thermistor wire and the other one. Replace the dryer control electronics (part #8546219).
Remove the screws attaching the top panel to the rear of the dryer then slide the panel rearward and lift it off.
Facing the front of the dryer, the dryer control board is located on the left mounted behind the bracket. Remove the three screws holding the bracket in place then rotate assembly up and set it on the side panel.
Disconnect the wiring harnesses from the control board one at a time then connect it to the new control board.
Remove the control board mounting screw near the transformer then press the side ends one at a time to release the mounting tabs and lift the end away from the bracket.
Secure the new control board to the bracket and reassemble the rest in reverse of the steps given above.
