Did you typo the 1/5 hp?I cannot find any that low.Here is a link to one from Sears,not your exact model,but many look the same.The manual to download is on the page.Your info is on pg. 28 of this one.It does show adjustment controls.It says to turn the screw counterclockwise one turn for every 2 inches of movement required.It also shows both controls are in the same area on the side.Seeing how you do not have the manual,did you see 2 screw sets available?

Hi Bob. Turn the adjustment you have 1/2 turn in either direction. It will either raise it a bit or lower it a bit. Once you know which way to turn it [typically clockwise to lower it] then gradually make the adjustment you need. Joe

Door closes only by holding control button down thru the time of operation?


Either you have an obstruction between the two sensors on floor on each side of door or the safety circuit is defective.

Make sure both are properly connected. One should be lit up and when you place something in between the sensors the light should go out.

My Chamberlain Liftmaster Professional 1/2 HP door goes down all the way but then it comes back up again. I see nothing in the way at all. is there some way to adjust the sentsitivity on it???


If the door is hitting the floor and then reversing you need to adjust the down limit control. This control is on the side of the motor unit. Turn the control a couple turns in the opposite direction of the arrow printed on the cover. This should stop the door short of the floor. Now some tweaking of that control will most likely be necessary to get it just right. Just remember if you run the motor too much it will shut off on the thermal overload and you will have to wait as much as 15 minutes for it to cool.

I have Sears Craftman 1/2 HP garage door open that want stay shut when you push the remote the sensor wire broke fix that. Now the door goes down and come back up. All sensor are led light are green...


Check the sensors again. Our unit has one amber and one green when working and if something (even a weed) breaks the optical beam it reverses and the lights blink. We've also had bright sunlight interrupt the beam. (The test for this issue is to stand such that you cast a shadow onto the sensor without being in the beam and then attempt to close the door with the remote). Next check if the door is binding during travel. If it is, check the tracks for plumb with a level and make sure the door rollers and tracks are undamaged. If a rail is crimped anywhere, it could be cause the problem. You can find some garage door sales places that sell the track sections and rollers to replace damaged parts. Check your local phone book and call around. In some cases, the door jamb may be damaged (lowering the header and shrinking the entire door area). This may require calling a professional to fix.

If the door itself is moving easily, then it sounds like the door might be hitting the floor too lightly or trying to go past the floor and triggering a safety reverse. On most of the openers, there are several adjustments you can work on to reset this. First try adjusting the down limit to above the floor and then bring it back to the floor. (However, usually these do not make the opener light blink.)

Alternatively, adjust the downward force to a higher value.

Without knowing the model of your Craftsman opener, I'll just use the directions for mine. All of these are adjusted with a flat blade screwdriver. Always test each adjustment with a complete up and down cycle.

The height limit control is on the side. (It's the forward one of two screws inside the cover - you should be able to reach them thtrough holes in the cover. Unfortunately, sometimes it's easier to get to them after removing the cover. The cover is held by 4 screws - 2 on each side.) To decrease the travel, turn the Down screw clockwise. One full turn of the screw is 2" of door travel.

The force controls are on the back with the down adjustment on the right. Turn this clockwise in 10 degree increments and test each time.

It is possible to overheat the opener with too many open and close cycles. In that case stop adjusting the unit and wait 15 minutes for it to cool.

I hope this helps.

Changed the blades on my mower&now it sort of scalps on one side while mowing.is this an easy fix or am i stuck in a repair waiting line?


First If you have a flat spot cement floor drive the mower onto the cement then drop the deck to mow Shut power down and engage blade mechanism, next get a tape measure and measure on one side the the other on the from and rear corners is the deck level? if not look at what might be causing it to be out of alignment. if it is level all away around then there may be a problem with the blade. check the side that is doing what your saying see if it is level or angled upwards in the front or back, if the deck is not level you should be able to figure out what is causing it. thanks for using fix ya and if you need more help just post what you found.

Roller door touches bottom cement and reopens again


Your door is traveling too far in the down direction. Locate the 'down limit' control on the side of your motor unit and turn the control one full turn in the opposite direction of the arrow printed on the cover. Some tweaking will probably be necessary to get it just right.

Craftsman 1/2hp garage door opener does not go down to floor


I'm no expert, but on a previous door opener I had (don't know the brand), the side adjusting screw basically adjusted a limit switch, which was located inside the plastic housing (where the motor is). I was able to remove the housing, figure out which limit switch was actually being contacted "too soon" on the way down and adjusted it while watching it.

Just a suggestion, you might take a look.

just keep your hands out of the way of the chain and sprocket if you do take the housing off. .

Door wont close all the way


NOT SURE WHAT UNIT YOU HAVE .
ALL OPENERS HAVE AN ADJUSTMENT TO TELL IT HOW FAR TO GO UP AND HOW FAR TO GO DOWN. LOOK ON THE SIDE OR UNDER A LIGHT COVER.IT HAS TO BE THERE SOMEWHERE
