Chamberlain screw drive opener

The plastic peice that runs along the screw seems to be stripped...when it's engaged with the door it wont hold enough to lift it...just makes an awful noise "stripping".
I assume that peice needs replaced...how do you get the new one on...how do i get the part?

The replacement part is available from chamberlain for replacement. I suggest the door be serviced by an experienced technician as the door is probably too heavy for the motor to lift, thats how the part became stripped in the first place

Chain on garage door not moving but motor is running. Model 1255SCR 1/2 HP.


This means that the nylon drive gear in your unit has been stripped. This can be replaced and is common in openers. You can get a replacement at chamberlain.com. It does take moderate skill to do and should take about an hour to complete. You can order the gear by itself or the whole drive shaft. Make sure and set the limits per the manual and do a 2x4 safety reversal test afterward. Thanks BB

DOES IT MOVE AT ALL OR JUST RUN??

IS THE ROPE RELEASE PULLED??

IF THE GEARS ARE STRIPPED IT WILL NORMALLY MAKE A GRAVELLY SOUND. AND THE DOOR WILL MOVE BUT NOT LIKE IT SHOUL.

TRY DISCONNECTING THE DOOR FROM THE OPENER & SEE IF THE TRAVELER MOVES NORMALLY.

1/2 craftsman garage door opener is not traveling more than 10 inches, it is not hitting the limit switches df


The final locking piece on the motor shaft (the one with 2 set screws) was not far enough onto the shaft. The plastic cap that works with the RPM sensor would not sit far enough on the shaft and was not being read by the sensor.

I held the motor shaft in place from the front and pressed the ring further onto the shaft; tightened the set screws and pressed the plastic cap back on the end of the shaft.

The RPM cap sat far enough into the sensor for the door mechanism to work properly.

My Chamberlain 1/2 HP garage opener moves slightly down and then just humms. It will then reverse to bring the door up. I have checked and the sensors or not blocked or misaligned. The door opens and...


DOES THE LIGHT FLASH AND MAKE A CLICKING SOUND??
YOU DIDN'T MENTION IT BUT IF IT DOES THE PROBLEM IS LIKELY IN THE SAFETY EYES.


YOU COULD HAVE A BAD GEAR KIT OR SIMPLY A SENSITIVITY ADJUSTMENT THAT IS OFF.

TRY INCREASING THE DOWN SENSITIVITY ABOUT 1/8 TURN.

IF THIS DOESN'T HELP UNPLUG THE UNIT AND TAKE OF THE COVER IS YOU FIND WHITE PLASTIC POWDER THE GEARS ARE STRIPPED AND A GEAR KIT IS NEEDED.

I can hear the opener click when i press the button, the light comes on but the door wont move


This usually means a safety sensor issue. Try holding down the wall button. If the door moves downward as you hold it then it is the sensors. If it does not it is probably a capacitor. YOu can get replacement parts at searspartsdirect.com. Thanks BB

Need to replace carriage on stanley sd450 opener how is it done?


Please make sure you don't have broken springs first and that the door is balanced properly. If so you can replace the "Trolly" by disconnecting the arm from the opener, undoing the opener from the bracket that mounts it to the wall. This usually takes a 1/2 in wrench. Then swing the opener out far enough to slide the trolly off and replace it with a new one. Re-connect everything then re-engage the trolly.

Garage door model PD200


Take the back cover off and see if the Gear that turns the shaft that operates the chain to lift or close is in good condition.
The gear is probably plastic and 3" or 4" in diameter.
UNPLUG THE OPENER AND DISCONNECT THE POWER BEFORE DOING THE ABOVE.SAFETY IS ALWAYS FIRST.
