Step 1 should feel some resistance against the movements. If you cannot
feel any resistance, you will need to replace the motor. Repeat the

6. Check for current: perform the test on the large motor connector
with 4 cables: there must not be any current between pin 4 (earth
wire) and the other three cables. If this test fails, replace the motor.
7. Check the thermostat: disconnect the thermostat wires (yellow)
at the connector. Set your multimeter to ohms: the resistance
should be 6,2 kohms.
