I have a heatseal h425 and it is making a loud sound when turned on. The rollers are not rolling and it feels very hot on the outside of the unit.

go to youtube and watch the video on GBC ultima65 film loading. sounds like you are not using a threading card to load laminator. Manila File folders work great to load laminators Westco Laminating Svcs 405-324-6092

Un-coil the lower roll and feed it through by hand.

To be honest other than checking the obvious like the plug fuse, plug wiring there is not much you can do. If you are ok with a screwdriver you could check internally for a loose wire but parts will cost as much as replacing the unit for new

Hi, i strong recommend you.
1) LUBE the bearing of Roller, the noise can be the Bearing of
Roller.
2) And after LUBE if , the noise is coming again replace the Roller.
3) However you can test the motor outside by turning by hand. Lube slight the shaft with WD-40 and Run again, if the motor make noise Replace the Ball Bearing, or replace completely the Motor,

something inside obviously is awry

so what model are you having troubles with

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.

I fix roll laminators for a living. Its best with GBC machines to remove wraps where the film is stuck to the roller hot. trying to remove ilm adhered to the roller cold can not jusst remove the film but the rubber roller surface. Do note GBC heat rollers espically the red ones are over 500 bucks each:( Its easy to damage those rollers making the machine junk....

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.
