GARAGE DOOR

[Kashif Haider]

My garage Door 139.53635srt not working if I click my wall opener I just hear a click and the light blinks on opner 5 times. nothing happens any idea guys

Did you check the sensors on each side of the door?

[Ed Pawlowski]

Check the manual troubleshooting section. The 5 blinks may be a trouble code telling you what the problem is.

That's how mine behaves when there is something blocking the sensors. Or the sensor is kaput.

mine does 3? don't remember, when the RF is LOCKED. but that shows up as flashing at the console controllers.

The manufacturer, Chamberlain, is sketchy, but 5 blinks seems to indicate a problem with the RPM sensing. Here are some error codes that may apply to your model:

1 blink: Protector open, misaligned, or obstruction lasts more than 4 seconds 2 blinks: Protector shorted or connected backwards for more then 4 seconds 3 blinks: Command input shorted to ground for more than 4 seconds. 4 blinks: Protector intermittent

5 blinks: No RPM in the first second

6 blinks: RPM pulses detected after the motor was turned off (perhaps forcing up travel)

Before working on the opener, unplug its AC power cord or disconnect its circuit breaker in the breaker box because there's plenty of exposed high voltage inside the opener. Stand on a wooden or fiberglass ladder, never anything metal.

All openers made in the past 20 years or so have a sensor that measures motor rotation (and therefore RPM, direction, and the force of any obstruction), and Chamberlains use an optical type consisting of a shutter/chopper wheel at the end of the motor shaft that rotates and a small stationary circuit board housing an LED and optical sensor. They may look something like this:

Because the sensor is optical, dust could affect it, so try blowing on it through a straw or squirt canned air. If that doesn't work, try spraying with isopropyl alcohol or CRC brand Electronic Parts Cleaner (hardware stores, auto parts stores, and electronic supplies sell it). Be sure any spray you use is 100% safe for all plastics by spraying some on styrofoam and verifying that it doesn't affect it at all because some solvents will make the LED and sensor frost up, rendering them useless.

While you're looking at the LED & sensor assembly, see if it's come loose (cracked plastic, mounting screw worked out -- motor vibration is awful for those things), and reseat its cable several times, both at the assembly and at the other end that plugs into the larger circuit board. It also wouldn't hurt to look at the solder joints of the assembly and where its cable attaches at the big circuit board, again because of motor vibration. Cracks in solder are oftne invisible without a bright light and magnifying glass.

About the only other things that will prevent motor movement are a bad motor capacitor (about 1" - 2" diameter and 2" - 5" long, but a bad capacitor will usually still make the motor buzz briefly) and a bad motor relay. The big circuit board usually has 3 relays, 2 for the motor (one for up, the other for down), one for the overhead lamps. They're typically plastic cubes and are standard parts available from electronic or electrical supplies (Mouser, Jameco, Digi-Key, Allied). You need an exact fit, again because of motor vibration.

Protector connected backwards for more than 4 seconds?

How would it be connected backwards for less than 4 seconds? Perhaps during installation if the installer noticed the error immediately, but in that case the power probably wouldn't have even been on.

It seems strange to have a time associated with a reversed connection.
