Please Help Diagnosing Garage Door Opener Problem!



Question:
I was hoping that won't be the logic board...Last time I checked, I was about $75.00 without shipping..The worst part is that I don't even know if replacing the board will even fix the problem :-( I'll try to examine the board to see any obvious burnt mark like you said...Thank you the suggestion! From the bottom of the linked page, there is a "diagnostic codes" table that shows the meanings of the number of LED flashes on the logic board. The LED on my board would flash 5 times every time I try to operate the opener, and according to the table, this incates "Possible RPM sensor failure/Motor overheated - unplug to reset" Well, I've unpluged and re-pluged it a hundred times already...Does this mean the motor is toasted??

Answer:
Long before wildly speculatiing (try this; it must be that, etc), first establish what is not a problem. For example, if garage door has lost balance or cable pulley bearing have become rusted (require grease), then motor will cut out to protect that 1/2 HP motor. What happens when door is freed from the garage door opener. Does door open and close freely with minimal human effort? If not, long before blaming the door opener, first get door pulleys greased or door balancing springs fixed / adjusted.
