Sensor test on LED ?

[IM2HAPPI]

Got the clear sensor board fixed, got the homing sensor fixed now have a close door sensor error 134. Been looking in search cant figure this out. Have cleaned them very well. Isnt there a test you can do on the led screen. Thought I had read it on here but now cant find, any one know ?
Thanks in advance

Tuen machine on, press "0" and then "7". This takes you to the sensor test menu.
