Q:

installing the receiver logic board 13953672SRT3 Craftsman Garage door opener

A:

Thank you for being Sears’ valued member and for contacting SearsPartsDirect.com with your question about your Craftsman Garage Door Opener model 13953672SRT3. I am so sorry the receiver logic board needs to be replaced. I will be happy to help you with this.

Safety Warning: Be sure to disconnect the power supply to the garage door opener before beginning this repair. If your garage door opener has a back-up battery, be sure to disconnect it also. Failure to disconnect the power could result in property damage, serious injury or death from electrical shock.

Replacing the receiver logic board is fairly easy. There are no special tools required. I have included the link below for our step-by-step guide.

Q:

Can't get garage door opener to close the garage door 13953672SRT3 Craftsman Garage door opener

Q:

Remote garage door openers

A:

see if the remotes will work to close the door when the main light goes out. when you are out and come home using the remote to open the door the main light/s are not on and the remote will open the door from the outside and when inside you use the wall button. but when you leave the house you open the door with the wall button drive out and try to close the door with the remotes which will not work. so set there and wait until the main lights go off and see if the door will close with the remote. if this is what is happening most likely the logic board has a short in the light circuit and when the light is on the remote RF signal will not reach the logic board until the lights shut off eliminating the short. or you changed the light bulbs and are using the new style that will cause the signal interference. if the remotes work after the light is out try removing the bulb and try the remote again if the remotes work the it is a bulb issue and if not the logic board is bad.

I know that it can be very frustrating to have issues with your garage door opener. From what you are describing, only two parts can cause this type of problem. Either the logic board or the safety sensors. It is possible that the sensor can be aligned and not working. If the sensors are not working properly, you could have a problem with the wiring. A common method of testing the sensors if you suspect a wiring problem is to use short pieces of wire that are known to be good and then connect the sensors with the short pieces of wire directly at the motor unit of the garage door opener. Hold the sending unit and receiving unit together so that there is no question that the wiring and the alignment is good and obviously not blocked. If you don't feel comfortable doing this yourself, please click on the link to schedule service: Sears Home Services. Click on "Get Started" and follow the directions, click on the red "NEXT" button to continue. I hope this helps. Please feel free to let me know if you need further assistance. We are always here to help. Thank you for using ManageMyLife.com.

I am having a similar issue - and tried the suggestion above posted by anonymous. The remotes will work when the light goes off either by timing out - or if I turn the light off at the main wall unit. The problem was not resolved by taking out the light bulb. But the remotes work after the normal time out or manually turning off the light bulb socket at the wall unit. Does this mean the logic board needs to be replaced? The part number on the outside is 41A5021-2C. Model number is 139.53675SRT2

yes the logic board has a short in the light circuit and will not receive a RF signal from the remote until the light circuit is shut down eliminating the short. if the opener is old just get a new opener you will have about 100.00 or so in the logic board which you can replace yourself they are not that hard to replace and you can't get the plugs wrong they are different and will only plug in one way. but a new opener is around 139.00 or so and even less when on sale. have seen 1/2 hp on sale for 99.99. you would want to open the cover and look at the plastic gears also before making your purchase if the gears are getting chewed up a little that will be another repair for 35.00 on an old opener.

one related question on a new opener. Would I be able to use the existing T-Bar, chain and sensors and just install the main unit...Or would I need to install all the components of the new door opener. Not sure if the gears are similar between the old and new??

A:

they have used the same gears for a long time now. I don't do any installs just technical repairs but have been told if you stay with the same chain drive you can sometimes just remove the head unit and change that using the old t-rails and sensors and chain but have not done it myself so I can't be 100% sure just using the info I was told. the sensors are the same and can be wired to the new opener and save the new sensors for later when one fails. as for the old opener I would not throw it away I do know for sure there is some parts that are the exact same from the old and new openers. and would save you some cash later on down the road by having some parts on hand.

Biggest problem with these units seems to be interference from outside sources. Close proximity to power co transformers, microwave transmissions, satellite signals etc. Even coil style light bulbs affect them. I nearly went nuts trying to solve problems. I finally sat down and tried to come up with anything that emits signals I'd put into use after I installed the opener opener. There were 2, a wireless modem for my lap top and a wireless switch for an additional light in the garage. Since the receiver was plugged into the same outlet as the opener I tried that first. My headaches were over! Electronic "experts" will tell you that interference between these two items is not possible........? good luck!! P.S. Sure sounds like somebody's selling a lot of "logic" boards!
