Thank you. I’m getting a hang of this. For the exam unit 5 question #5 asks about the test point I choice L1 to N because there’s a fuse in series with that side of that capacitor so I would measure those 2 points first to indicate I’m still getting my line voltage input then if I do I can precede to check L2 to neutral to see if the noise filter is putting out the voltage I just find it better to follow sequence in order. Also for the video in this unit 5 the half splitting master Samuria was able to demonstrate getting 120v L1 to ground chassis with the dryer running and 0v through L2 to chassis and motor not running did he do this demonstration having the door open ? And then closed it to get the motor to run and get that 120v.
Thank you

Thank you Sam for the response.I’m still trying to figure this out so because the measuring point contact R is before the open in the circuit we are only measuring the difference between bk and R therefore its closed so we are getting 0V. so if we measure after R For example bk to orange we will get a voltage reading since there is a open? lets say we measure across the heating element on this circuit with nothing open we will get 240v? but for instance let’s say the thermofuse is open or the contacts between bk and R is open we wilL read 120v across the element because we will only we getting 120v from L2? sorry just trying to get a better understanding.

I got it. Thank you Susan.

Hi Scott, I watched the video of the stacked dryer. In the video you stated if everything was GOOD on L2 side and you measure from the bk and the R on the timer with the contacts closed you should read around 0v but if its stuck open you should read 240v but I got confused because in L2 circuit the conclusion was a open fuse so how would we still know the timer contacts are closing between bk an R on the time and getting around 0v shouldn’t we get 120v since it’s and open circuit?. please help me understand.
Thank you

Thank you susan, going back to that video in unit 3 did clear things up for me.

Hi scott, I am having problems with questions #7 and #8 in module 8. I think I missed the reading assignments in the reference book, is the reference book the major appliances book? where is the additional reading assignments usually posted for future reference.
Thank you
