We've been using this centrifuge for years. It has always required a little elbow grease to get the lid closed, but today we cannot get the lid to release off the latch that holds it closed! The electronic display reads "error 001" and the centrifuge won't start. We've tried unplugging it to turn it off and then on again. Any suggestions?

"Err 1" is a loss of tachometer signal. Does it clear when you plug it back in? Can you manually release the lid? The release is located on the underside of the machine, at the front right corner. It's a small plastic plug in the base - pry it out, and pull the cord until the lid releases. If you've had trouble closing in the past you may have to push down on the lid before pulling the cord, as it sounds like your latch isn't properly adjusted and is too tight, or possibly the switch is damaged, faulty, or loose. If you get a normal display with the power cord plugged back in, and with the lid open, spin the rotor by hand to see if you get a speed reading. If you don't, there's a tach issue.

"Err 1" clears when you plug the machine back in. I looked for the manual release you described and found it, but there it nothing to pull, I tried pushing on it with a screwdriver as I cannot get a finger or hand in there.

So, you popped out the the white plastic plug with a screwdriver and there was no cord looped through the eye?

Bummer. The cord must be loose inside. How about the lid release key, does it not open the lid with the error reset? If the lid is jammed you might have to press it down first before pushing the button. Otherwise you'll have to fish around with a paper clip or something to try to hook the cord out. Beyond that, you'll have to cut a hole in the front cover.

Hi,
It occurred to me that I may have led you astray here. By "OV" did you mean "old version", the one that looks like this? http://www.labequip.com/kz-content/images/large/IEC-Micromax-Microcentrifuge-6221.jpg

I have a similar problem, and yes, I do have the model that you posted an image of.

Hello Clanijos,

The procedure is:

1. Unplug the centrifuge.
2. Find the plastic plug beneath the centrifuge.
3. Prise out the plug with a screwdriver.
4. Pull on the attached cord to open the lid.
(If the cord is not attached then use a piece of plastic-coated wire to try to hook it)
5. Replace the cord & plug in the hole.

IT IS DANGEROUS TO DO THIS UNLESS TH UNIT IS DISCONNECTED FROM THE POWER.

IT SHOULD NEVER BE ATTEMPTED DURING ROTOR ROTATION.

The fuses are at the rear of the unit. Replace with same power rating. Model 3590: 6.52A, 3591: 4A, 3592: 8A, 3593/4: 6.3A, 3595: 8A, 3596: 10A. I cannot say which model as you do not state your country.

You can get a user manual here: http://www.scribd.com/archive/plans?doc=60089985

Hope this helps.
