How to reset the machine


Reset Procedure for Equator / Hirundo ( EZ3612CEE / EZ2512CEE / EZ1612V )
If the door of the machine is opening you can follow the below reset procedure so that the machine will function properly but if the door in your machine is not opening you need to first get the door to open by following the procedure as stated in the link http://www.fixya.com/support/r4240518-door_not_opening_in_equator_hirundo
Resting the unit will make sure that all the memory storage in the chip will be erased and hence the unit will be ready for a new cycle.
Reset Procedure
  1. Make sure that the machine is turned OFF.
  2. Make sure that the door is opening.
  3. Set the dryer & wash temperature knobs to the off position (12 o'clock / pointing vertically upwards)
  4. Make sure that the door is latched properly.
  5. Set the washer knob on the Red Reset position and switch on the power.
  6. You will observe that the mode + Door Lock light flickers rapidly for a few seconds and then flickers slowly.
  7. Once the light starts flickering slowly turn off the power.
  8. Set the washer knob to the Green Reset Position and switch on the power.
  9. You will observe that the mode + Door Lock light flickers rapidly for a few seconds and then flickers slowly.
  10. Once the light starts flickering slowly turn off the power.
  11. Set the washer knob to the Grey Reset Position and switch on the power.
  12. You will observe that the mode + Door Lock light flickers rapidly for a few seconds and then flickers slowly.
  13. Once the light starts flickering slowly turn off the power.
  14. Set the washer knob to the Reset Position on Delay Time and switch on the power.
  15. You will observe that the mode + Door Lock light flickers rapidly for a few seconds and then flickers slowly.
  16. Once the light starts flickering slowly turn off the power.
You have now reseted the unit and the unit should work fine now , in case you observe that the washer knob/Dial is going round and round all by itself now please go through the link for fault codes for further diagnosis.
Hope this procedure helps.

Guardian garage door opener not working,when I press the remote handheld button,the light in motor unit starts flickering. untill I press one of the 4 small switches,then it stops flickering. garage door...


Is your door jammed or could the door be moved smoothly? If not then the motor might not be able to start and it flickers, try to press "+" for open or close (depends on whether the unit is going to close or open the door) once at a time and try to remote it, this will increase the open/close force and may overcome the issue.One more thing, do the photo-eye sensors give unobstructed with good indication?

My mom & I each have a Craftsman garage door opener at our respective homes & live @ 15 minutes apart. Our openers are about 13 to 14 yrs old. The past two yrs. we've both had the same problem. ...


If the main light flashes 10 times when the door reverses to the open position it is a door sensor problem. Make sure both lights on the sensors stay on and don't flicker while the door is moving and the sensors are firmly attached so they don't move. Tweak them just a bit.

Craftsman 139.53673SRT1 garage door opener (1997 model) worked yesterday. Today the unit is not responding, the light does not flash, the LED blinks 5 times then stops and then starts again. Unit clicks...


Usually when this happens it is because the door is open and the trolley is jammed against the bolt just in front of the motor unit. Try loosening the chain to relieve the pressure on the trolley and then close the door. While the door is closed locate the 'up limit' control on the side of the motor unit and turn this control 2 full turns in the opposite direction of the arrow printed on the cover. Now tighten the chain.

Craftsman Garage Opener intermittently not closing


A couple things to check and do. If the main light flashes 10 times when the door reverses to the open position it is a door sensor problem. Make sure they are pointed at one another and that the small light on each one is lit and not flickering. Tweak them a bit if necessary.

If the main light isn't flashing it may just be a simple adjustment. Locate the 'down force' adjustment on the rear of the motor unit near where all those white wires go. Increase this about 1/4 turn and try.

For the light you should unplug the unit and then using a small screwdriver pull out on the center contact in the light socket.

You must make sure you followed the color coding of the wiring to the sensors. One wire is solid white and the other is white with a black stripe. Make sure the small light on each sensor is lit and not flickering. If nothing works then you must have a power problem. Make sure it is plugged in.
