SFIII Posted August 5, 2022 Share Posted August 5, 2022 My National 431 Food Machine spins left abut 1/4 turn then spins right 1/4 turn then quick left right small movements then stops. It seems to stop in the selection spot where you want it to by pressing the directional arrows. Then seems like the drum is having a hard time moving . I Cleaned the clear optic sensor disc to the left of the stop pin and still seems messed up. any input or suggestions would be appreciated 🙂 Link to comment Share on other sites More sharing options...
Vendo Mike Posted August 5, 2022 Share Posted August 5, 2022 Been years but I seem to remember the stop pin getting loss and needing to be adjusted from time to time. You might also clean the encoder wheel that spins inside the sensor you cleaned. Link to comment Share on other sites More sharing options...
