I had the same problem. It's prob the optical chopper/encoder wheel on the motor shaft that wobbled loose and scraped on the sensor until plastic filings plugged up the holes. remove cover and check the "u" type sensor the chopper wheel runs in. Mine was really crammed full of plastic so I had to take it it off and pick it out with a blade. when you reinstall make sure wheel runs between sensor with no scraping.

There is a small 125 v 10 amp fuse in the circuitry on the right inside the unit. Whether or not this will solve your issue is unknown. I have one apart in front of me right now with other problems.

You need to loose the vertical plastic wall on the left side, and pull it up and to the left, only then you would be able to take pink rollers and metal piece away. Step by step do this (BTW, make pictures of each step if you think you will not be able to assemble it back) :

Take the lid (3) off and hang it on the corner.
Next goes off (42) part.
Now focus on the left side. Take to the side part (30) with 7mm wrench. Then both parts (14) from both sides [4 in total]. Then both parts (2). Then take out screws that are holding this vertical plastic wall place. There is two screws from the outside of laminator in the bottom!
Then black roller (36) you lift up and take out by sliding to the side. Then two long black metal pieces.
Now you should be able to pull up and move to the left that vertical plastic wall on the left side of laminator. If not, try loosing some screws that are in this wall.
Be careful taking melted jammed stuff away from heating panel. Do not over-scratch it, as it is very sensitive.

GBC appear to just be a crappy company. I have a Heatseal H212, same problem. Worked fine then one day when I turned it on it never became "ready". I waited a while longer then turned it off.. except it wouldn't let me turn it off. I had to unplug it from the mains to get it off. After that, it would never turn on. Checked the fuse, it was fine.
