175b88 wsocket EZ instructions: IMPORTANT SAFETY TIP - DISCONNECT THE POWER FROM THE GDO
First, you may not need to replace the socket. The copper electrical contact at the bottom of the socket sometimes gets pressed down too far and the bulb doesn't make contact. Look at the contact, does it still look like copper or is it black or burned out? If it looks good, try bending it upwards to a 45 degree angle (gently) and see if that works. If not you may need a new socket.
Remove the plastic lens and bulb.
Looking at the socket 175b88 there is a front and back side. The back side locks in place. If you pull on the light socket a little bit, it will open a small space, about 1/8th of an inch away from the Panel on the FRONT of the socket. This is enough room to insert a flat head screwdriver and push to pop out the old socket.
When the socket pops out of the Panel, it will have 2 wires attached. The Orange wire goes to the back contact and the White wire goes to the front contact. On mine, the White wire did not have any insulation, but the Orange one did. So I wrapped the White wire in electrician's tape. Heat shrink tubing would have been better, but I didn't have time for that.
At this point, if you haven't done so already, bend the copper electrical contact that the bulb will come in contact with on the bottom of the socket UP, so that it is at an angle from the bottom of the socket. Do this with the flat blade screw driver by getting underneath the contact and bending it up. It's flexible, but be gentle.
Reconnect the power to the GDO. Now, insert a light bulb and plug the power back in. The bulb should light up. If it does, remove the light bulb and go to the next step. If the bulb does not light up you may have a bad bulb. Try another bulb or test the bulb with an ohm meter.
IMPORTANT: Now unplug the power to the GDO.
Reinserting the light socket into the panel:
There is a small "hook" on the inside back of the socket -- align that little hook on the back of the socket with the small cutaway that matches it on the Panel. Now push the front of the socket so that it snaps into place.
Screw in the bulb and reconnect power to the GDO
