Slow Door Closure

Hello, try contacting STERIS for additional assistance!

The cable tension need to at a perfect adjustment. You will need to play with the tension. If you motor drive is running smooth, the cable coating is in good condition, and the cable is in the guides that are working smoothly.

There are several reasons for this to occur and the 20" door are the worse.  I have had all the follow cause this problem/

1) Drive motor, can be slipping internally. Have had several of these.

2) Drive cable stretched and/or out of adjustment

3) Sterilizer not level properly cause door to lean and rub and it goes up or down.

4) There is an upgrade kit available, through Steris, for the pulleys which actually rotate as appose to the cable slipping on the pulley wheels. This kit help me on serveral occasions. 

5) Check all door adjustment and the teflon tips to the S.S guides screws.

That's all I have. Good luck, they can be a pain.

take a look at your counter weight. See if it's catching or leaning at all. does the cable look worn at all? could also be a failing motor or power to the motor could be out of spec.

Does the drive motor sound like it’s running smooth? 

Make sure the cable is in good shape. Adjust the bottle screw a bit. You may need to adjust several times to find the sweet spot.

We just replaced a motor box for the same reasons you described. It was the gears that is causing the intermittent movement they were gone. So check the gearbox.

If the cable is too loose it will slip on the wheel and open and close slowly. If it's too tight it binds on the wheel and now move.
