My garage door goes up after a power outage. Why?

Try a little experiment if you are handy. Kill the power at the circuit breaker. (there should be only one breaker) Turn the breaker back on. Does the door go up? If it does you have one of two problems as long as the door is one of the old hard wire types. (no electronics) One is an old rotary relay that is almost impossible to fix over the internet. The other is your radio receiver. Some old radios can actuate when the power comes back on. If you have one of the old radios you will have three wires going from the receiver to the motor. They will be hooked up to terminals 1 2 3. Write down the color and order and remove all three. Repeat the experiment. If the door stays down you have found the problem. To go further I really need the model #s off the motor and radio. PS The door opener is probably noisy because the screw needs grease. Use a tube of Genie grease and put a small bead down the screw. You can use a different grease just make sure it is low temperature. Then run the door and see. Email me if you need to.
