The resistance measures between 5 ohms and 10 ohms. If incorrect, disconnect the solenoid from J4 and check the resistance of the solenoid between J4-1 and J4-2. If incorrect, replace the solenoid assembly. If correct, replace the fuser control board. 3 Fuser Cable Check the continuity of the fuser cable.
