We have model#139.53662SRT and it quit running 1/2 way through the up travel. There is power and the door sensors along with the wall pad have indicator lights lit. On the side of the opener there is a light next to the "SRT" button which flashes 5 times then pauses and starts again. When pressing the wall pad or remote the light continues to flash and a sound simular to a relay comes from the area near the circuit board. My question is: do the 5 ligth flashes represent a trouble shooting code and is there a reset process to attempt before considering replacing the opener?

Chamberlain makes the Chamberlain, Liftmaster, and Sears openers.

They all have similar characteristics and designs.

I think that I have seen this same infomration in a Sears or Chamberlain 1/2 hp chain drive, but could not find it.

This is for the belt drive units.

So the actuall part numbers probably are not the same same as yours. But it has similar gear system, rpm sensor, and control logic.

Get this manual.

Then look athe diagnostic chart on page 30.
