7. Press the latch -
... and remove the electric fan control unit from the casing.
8. By external inspection, we make sure that the spiral is intact, that there is no charring or other damage.
9. Using an ohmmeter, we check the additional resistor of the block for a broken spiral. If a malfunction is detected, replace the control unit.
10. Install the electric fan control unit in reverse order.
