Chamberlain Powerdrive PD422D 1/2 HP Security Plus Screw Drive Garage Door Opener Questions & Answers
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.
My wife paired her Acura
unpair it as there is another signal in your area on the same frequency. some frequencies can travel over a hundred meters or more. if you use a frequency monitor you will find there will be a lot of signals in your area. the original system will drown these out looking for its signal but pairing a device that has a different frequency or frequencies this can cause randone read. and will work on frequencies in this range can even be a freezer turning on etc. as every device make a signal.
I have a SecuraLift Garage
Many of these devices use a code that changes each time the door is opened and closed. This feature is used to keep potential bad people from learning your operational code and entering your garage. You may have a communication problem whereby the Garage Opener needs to be reset. You may try to change the settings. If you have dip switches on the main unit in the garage, change the dip switches to another setting and write down the numbers in the order that you have the set them, Then go to the remotes, hand held and hardware placed on the outside door, and change the settings on these devices to MATCH up with the inside unit. This is a good time to REPLACE the batteries also.
I have problem, with my door garage. it desn't
IF THE DOOR OPENS WITH YOUR REMOTE BUT DOESN'T CLOSE (AND WORKS NORMALLY FROM THE WALL BUTTON) THE PROBLEM IS IN THE SAFETY EYES - CHECK TO SEE THAT BOTH LED'S ARE LIT.
IF NOT CHECK WIRING POLARITY - CHECK FOR BROKEN WIRES - CHECK FOR ALIGNMENT AGAIN.
