Craftsman 139.53663SRT garage door opener troubleshooting

One of the Craftsman’s most popular models, the 139.53663SRT garage door opener was created exclusively for residential use. It utilizes a 1/2 HP motor, which is the most common type for residential garage door openers. If the device is experiencing an issue, check the chart below for useful troubleshooting tips.

SituationProbable Cause & Solution
The opener doesn't operate from either the door control or the remote control:1. Does the opener have electric power? Plug a lamp into the outlet. If it doesn't light, check the fiise box or the circuit breaker. (Some outlets are controlled by a wall switch.)
2. Have you disabled all door locks? Review installation instruction warnings on Page 11.
3. Is there a build-up of ice or snow under the door? The door may be frozen to the ground. Remove any restriction.
4. The garage door spring may be broken. Have it replaced.
5. Repeated operation may have tripped the overload protector in the motor. Wait 15 minutes. Try again.
Opener operates from the remote control\but not from the door control:1. Is the door control push bar lit? If not, Remove the bell w ire from the opener terminal screws. Short the red and white terminals by touching both terminals at the same time with a piece of w ire. If the opener runs, check for a faulty wire connection at the door control, a short under the staples, or a broken wire.
2. Are the wiring connections correct? Review Installation Step 7, page 21.
The door operates from the door control, but not from the remote control:1. Is any door push button flashing? If your model has the Lock feature, make sure it is off.
2. Your opener needs to re-learn a remote control code. Refer to instructions on the opener panel.
3. Does the batten, test light glow when the remote control push button is pressed? If not, replace the battery.
4. Program the receiver to match the remote control code.
5. Repeat the receiver programming procedure with all remote controls.
The remote control has short range:1. Check the battery test light. If the light is dim, replace the battery.
2. Change the location of the remote control in your car.
3. Check to be sure the antenna on the right side panel of opener extends fully.
4. Some installations may have shorter range due to a metal door, foil backed insulation, or metal garage siding. (Antenna Extender Kit 41A3504)
Opener noise is disturbing in living quarters of home:If operational noise is a problem because of proximity of the opener to the living quarters, the Vibration Isolator Kit 41A3263 can be installed. This kit was designed to minimize vibration to the house and is easy to install.
The garage door opens and closes by itself:1. Be sure that all remote control push buttons and battery indicator lights are off.
2. Remove the bell w ire from the door control terminals and operate from the remote control only. If this solves the problem, the door control is faulty (replace), or there is an intermittent short on the wire between the door control and the opener.
3. Clear memory and reprogram all remote controls.
The door doesn't open completely:1. Is something obstructing the door? Remove the obstruction or repair the door.
2. Ii'the door has been working properly but now doesn't open all the way, increase the up force. See page 29.
