it depends on when it was made but there are only 2 places
take the back pannel off you will see a belt look to the bottom of the belt which is fixed to the motor
2 to 3 inches to the left you will see 2 thick wires and 2 thin wires the 2 thin wires are fitted to the thermostat you can take this out by turning the 10mm nut four times then just twist and it will pull out
the other place the stat my be located is at the front of the drum you can see this by tilting the machine back and looking under neath
