It's not hard, just don't be scared!

first have your head removed, that's another thread but don't worry, it's coming.



Here's your part #



Now we are going after six 3/16 nuts. 4 in the corners and two on the back. You might have to break out the small guns for this hard to reach one.









Once all the screws are removed slide the guts outta the housing. Here's the top, and the bottom. Give these a once over for any signs of damaged electronics though this is NOT the piece we will be focusing on when we are cleaning.





To get the controls start by lifting out the wiring harness.




Then gently pry apart the board from the head. there is a pin socket holding the two together. you can also insert something plastic between the two to help get them apart. the trick is go slow and don't rush



Once apart we can begin to take apart the head. First take the two screws out.



then begin to pull apart the head from the housing



once apart the rubber contacts may or may not still be attached to the housing.

You should end up with these parts on your table



The dirt and residue that needs to be cleaned off resides between the rubber contacts and the front of the controls.





My head was not dirty and was not the cause of my problem but it was a good exercise anyway. Tools needed for the cleaning. Your solvent of choice, mine is 91% alch and q-tips.



Dip q-tips in solvent and begin to clean contacts on board.





next give the rubber contacts a cleaning.




and if needed the housing itself if grimed up



While your waiting to let it all dry you can verify buld function by taking them out and connecting to a dc power source if you have one.








and that's how you clean your head. The reassembly is just the inverse operation. I'll post the rest of that tomorrow. I gotta get running!

Great pictures and step by step write up!
