The microcontroller, also known as the Eprom, can be swapped to incorporate new improvements to
the programming.
·
Use the necessary precautions for handling static sensitive devices.
·
Do not attempt to pry the chip out of the socket with anything. This will damage the casing.
Tool required:
You will need to purchase a PLCC Extractor as showed in the diagram below . This
can be found in most electronics stores or via the internet. Without this tool, you may damage the
casing for the microchip and damage the board.
Removing
1. Turn off the machine and unplug from the outlet;
2. Open the door and remove the plastic protection via the 4 screws;
3. Locate the microcontroller (the black square piece in the middle of the board with a white label);
4. Using the Extractor, carefully insert the prongs in the top right and bottom left corner slots of the
casing and grab the microcontroller;
5. Pull out of the socket gently.
Replacing
1. Align the notched corner of the microcontroller with the notched corner of the empty socket;
2. Make sure that all contacts are aligned with the appropriate slots on the socket;
3. Push the microcontroller firmly, straight down until the top of the chip is flush with the top of the
socket;
4. Replace remaining parts in the reverse order;
5. Plug the machine in and turn on the unit;
6. At start-up, the screen will indicate the microchip version #, see picture below;
