I received a Gillette ProGlide which stopped functioning after couple years. Recently it resurfaced after a house clean-up. It had a leaking AAA battery which was removed and disposed off. With the gunky remainder, I squeezed out juice, from a lemon hiding in the fridge, onto a cotton bud then rigorously swabbed until the innards were clean.
It still didn’t power up. 🙁
Then i thought of disassembling the entire device. I found the two metal clips on the blue holder, seen only by removing the end cap. By pushing the two metal clips inwards, the entire motor and switch assembly can now be removed.
Pulled out the entire metal assembly to find the following:

The blue pushdown switch in the centre of the PCB is the on-off switch. Sticking in a fresh AAA battery, the motor on top, spun continuously until the switch was depressed again.
So this works!
Reassembling was pretty easy. The ProGlide did not require the two metal clips to be put back into place, as the bulbous end cover held the entire assembly tight. I just made sure the motor and switch assembly could slide into the housing. Rather effortless.
Then tested the razor assembly one last time by pressing the blue switch before covering the hole with the silicone button.

Razor assembly repaired! 🙂
How do you remove the metal clips from the housing?
You’ll need to remove the battery cover (bottom) to get access to the metal clips on the side. Use a small metal pick to lift the metal clips.
