Boil vs Bending - Will Boiling The NES 72Pin Really Work?

Is your NES failing to read games? Blame the 72pin connector.

For many years the most common way to clean and adjust the NES 72 pin connector was manually bending the pins back to position. This method is still very useful and valid in certain situations. You can view my older article here. which also describes how to disassemble the NES and remove the connector.

I first heard about this method years ago. I gave it a try on the worst 72pin in my collection. Boiling did not fix the connector during that first test.  I immediately figured the boiling method was hype and never revisited the process.

Skip ahead a few years and I decided to try the boiling process again.  It worked beautifully!  To my surprise the boiling process offers more than cleaning and breaking loose dirt & oil from the metal. The heat relaxes the metal and allows it to more closely assume its original shape.

In my opinion this is the main advantage with boiling, the pins assume the original spacing set from the factory.  This is very difficult when manually bending pins as seen in my photo above.  Often the pins are too tight after manual adjustment.  Boiling brings the NES back to factory specs and is easy to do and difficult  to mess up.

Manually bending the pins may be needed after boiling, so far I have encountered that.

How to Boil:
(I am not responsible if you break yourself, the kitchen or the 72pin)

1. Place the connector in clean preferably stainless steel pot. I would suggest using a pot that is not used for cooking. It is a good practice to keep mad scientist projects and food separate.
2. Add enough water to fully submerge the connector. I suggest placing it front side down, the force of  boiling bubbles will be directed inside the pins. Don't worry, the plastic will not melt.  
3. Turn the burner on high heat and bring to a rolling boil. Let the connector boil for 30mins.  
4. Allow to cool, rinse and fully dry before installing.  A hair dryer can speed up the drying process.
