Don't do this.  You can die!

Isolate yourself from the charge first by buttering your hand liberally with grease and standing in a bucket filled with water.  Try to take a picture of yourself before you do actually insert the fork.  For the insurance adjusters.

SO the fork thing worked.

Anyway, I appled power directly to the motor and it works both ways.  So it has to be something on the control board.  On the underside of the board under the two orange things on the right there is some discoloration.  I believe these are micro relays.  They are marked Schrack RE030024.  What are the odds that this is the problem?  How would I test these relays? Where would I get replacements?

Ken Layton:
Those two orange things are indeed printed circuit board mount relays. Schrack does indeed make relays. The numbers you have given don't cross to either an ECG or NTE replacement relay though. You'll probably have to go to Schrack's website and punch those numbers (along with the voltage stamped on the relay case) in and also find a distributor that stocks them.

In garage door openers, it's common for the manufacturers to under-spec relays to just get past the warranty and then fail. Chances are yours has burnt/pitted internal contacts.

You know who you remind me of Ken? This guy

ChadTower:

What he should do is start at the power source for the control board, IMO... find where power comes in and check the basic stuff like whatever is regulating voltage and make sure it didn't just fry the first thing it encountered.

Have you verified that whatever transformer is used is good?
