Door wont go down unless I hold the button. Also wires loose in

Connector at the motor, how do they attatch and stay tight?

  • ltrbaz88 Jun 10, 2009

    I dont see ANY lights on the sensors so maybe this is the problem??? Also how do the wires attatch to the small connector inside the motor housing? There seems to be a connector that holds about 4 different connections and some seem loose?

Your door sensors most likely have been bumped or misaligned. Each of them has a small light that should be on when aligned. Tweak them until they are lit. What is the make and model of your opener?

Ythe door goes up fine but u have to hold the button for it to go down

Normally this means that either your transmitter needs to be reprogrammed or you may have loose wiring. OR the alternative is that one of your sensors could be dirty or misalligned and you might not know it. Check the users manual and your door buttons to see if any wiring is faulty or loose. Most of the time it has to do with sensors. Holding button down is a manual bypass to force the door to go down. Something is telling it to stay up. Check your sensors. They can be easily moved, jarred, or knocked loose by accident.

Garage door won't close unless I hold down the wall button until it is fully closed. Checked the L.E.D light at motor and it flashes 2 times in about 8 seconds. Sensor with amber light is on, other does...


WHEN HOLDING IT DOWN MAKES THE DOOR CLOSE PROPERLY THE PROBLEM IS IN THE SAFETY EYES.


CHECK FOR A LOOSE OR BROKEN WIRE.

ARE THE EYES WIRED CORRECTLY?

ARE THEY AIMED AT EACH HOLDING DOWN THE WALL BUTTON OVERRIDES THE SAFETY EYES.

Lg 52sx4d not starting up

The flashing green bulb light means the access door for the bulb on the lower right side of the TV is open or loose. There are two screws that hold it in. If they are tight, maybe the interlock switch is bad or disconnected. Open the door, and hold in the little white interlock button while turning on the TV. If it still doesn't work, there are wires leading from the switch to a connector about halfway across the TV on the bottom. Connector might be loose. Unfortunately, it is hard to reach. You might have to remove the screws across the bottom rear edge that hold in the chassis and gently slide it out to reach the connector.

Want hold a charge

get a test light and a schematic. unplug stator plug.start bike ,make sure battery has full charge. test each pin on connector that is attatched to the 3 yellow wires.should light on each pin. if all good check for burn marks around connectors, front & back sides, and on wires. if no power on yellow wires, stator problem. if power, plug connector together, now test for voltage in wires on the voltage regulator side of the connector, to see if the voltage is making it through the connector.if there is power to volt. regulator,test w/ multi meter across battery leads to see if there is charging voltage to battery,approximately 13-15 volts. if only battery voltage(12.2 or less) while bike is running,voltage regulator is no good.if charging good, but bike wont start after prolonged sitting(say overnight) a system amp draw test is needed to see if something is staying powered up while bike is not running, drawing down battery.
