I dropped a jar in my fridge tonight and broke off the switch/tab which pops out to control the light, door alarm, etc. I just ordered a replacement part from you and wondered how in the world to install it (when it arrives). I can’t imagine how the old part will come out and the new one go in. Thanks in advance for your help. 
The following should help, see page 19.

You will have to join the site to download the manual but it is free and has service manuals for many units, a great resource for the appliance DIYer.
I appreciate your help. I hope I can do this !! 
If I can do it you can do it.
Just be sure to unplug the fridge.
