Is there a battery in the Craftsman 315 MHz Garage Door Opener Premium Control Console?


The Premium Control Console on the inside wall of the garage is hard-wired to the garage door opener. When I've needed to press and hold the button on the unit, there's usually something wrong with the opener or the garage door hardware.

The problem could be with the travel or force adjustments. However, more likely, the door is binding during travel or the garage door opener gears are damaged. Disconnect the door from the opener and check how it opens and closes. Is the door binding anywhere? Check if the rails are bent or if the framing of the door has rotted at the bottom. (We had one garage door where the door jamb was damaged. This led to the doorway shrinking and the door jamming.) If you open the door part-way, does it stay at that position? Do this test carefully; you may get injured if the door falls. If it doesn't stay open, then the torsion spring tension may need off or the springs need to be replaced. If the springs are mounted next to the doorway, you need a professional to check the springs. (If the torsion springs are further from the door, you may want a professional to check them. You will need to use vise grips or a similar tool to keep the door partway up and prevent it from falling when you adjust the tension. You will need to adjust both sides evenly.)

When you press and release the garage door opener button, how far does the door travel? Do the opener lights blink three times? Are both obstruction sensor (often green and amber) lights lit? Please add a comment with more information about the symptoms for additional help.

I hope this helps.

(note: when there is a problem with the door binding or the torsion springs failing, it's not uncommon to see the garage door opener fail. The motor tried to force the door and the plastic gears end up stripped. You may need to replace or repair the opener after fixing the door hardware issue.)

Door opens about 16" then stops will go down but only opens 16"


Probably a broken torsion spring, if you help lift the door as it is opening, it may open all the way. With the door down and you inside, look at the torsion spring above the door opening on the long rod to left or right of centre. One on each side of centre with a double garage door. If either spring is in two pieces, then you will need to get them replaced or replace them your self.

Release the garage door from the opener and open the door by hand, if it is vey heavy you may have a broke spring inside the torsion bar above the header, check then to see if the opener goes through the complete cycle O K with the door not attached. If you don't have a broken spring you may need to increase the up force on the opener head.

Fuse blew as garage door was closing.Door slammed shut ,now only goes up 2inches then closes when switch touched !!!


Sounds like it may be a broken spring. Look above the door at the coils on the steel rod and see if there is a separation of the torsion springs. Or if extension spring it will be hanging down on one side above the tracks. If it is a broken torsion spring I would advise calling someone with experience. If not what is the make and year of opener?

Torsion spring is broken for our liftmaster 2265R model garage door opener and i need a new one where do you buy one?


Here are instructions for replacing the spring. You can call any local garage door company and they will sell you the springs. I absolutely don't recommend this job for a DIY'er. It is dangerous.

Have 1/2hp garage door opener that will not open the door. If the remote pad battery is dead will the opener stop working? if I press the remote opener the door move about an inch stops and the light...


Dead batteries will not cause your problem. If it is the main light flashing 10 times when you try to close the door it is a door sensor problem. Make sure the small light on each sensor is lit and not flickering. Tweak them a bit to make sure.

Door openly opens 5-6 in, then stops.


If the door isn't unusually heavy when you open it manually then maybe an adjustment will help. On the back of the motor unit you will find the 'up force' control. Increase it 1/4 turn and try.
