Re: garage door opener questions

[Steven Trovato <strovato@optonline.net>]

You know, I have a Sears opener too, and when I get the "flashing 
light" it is because of the safety beam thing.  Either a broken wire, 
beam misalignment or bugs/dirt/leaves obstructing the beam.  The 
other issues regarding force, and other  mechanical faults cause the 
door to do similar things, but the light does not flash.  The only 
other time I've had the light flash is once when the main board was 
fried from lightning.  That part costs almost as much as the whole 
opener, so if that's the case, just replace it.
