On the side of the motor unit you will find the 'down limit' control. Turn this in the opposite direction of the arrow printed on the cover. Some tweaking will be required.

Drivers side window will not go completely airtight when up.drops and goes up when door opens and shuts, but not high enough to seal correctly


My 02 had this same problem, the glass has shifted position in the mechanism. You will need to take the inner door card off to get at the mechanism, lower the glass about half way then reach through the large opening in the door panel to feel for the large 'cog' shaped retaining bolts that hold the glass to the mechanism (one either side, both facing the outer door skin). A 5mm torx or allen key bit is required to loosen both 'cogs'. You can then adjust the glass position. This is possibly best done with two people...once the glass is loose, make sure you move the glass first to break the seal (it may have stuck to the rubber seal over time, so will not move much), then gently tighten into place, raise the window to the full up position, shut the door fully, then with the help of an assistant, one inside the car one outside, move the glass into the desired place and tighten the cogs. Open the door, fully lower and fully raise the glass, then keep the switch in the up position for 5 seconds, this teaches the ECU the new position. Check that the window closes when you open and close the door, if not, try adjusting the glass angle with the adjustment screws located at the very bottom of the door. When in the right position, you should just be able to pull a sheet of paper past the glass and the seal. Boom, done!

The down adjustment broke off


Check the micro switch that will be activated when the door reaches the closed position. It might need to be readjusted as it is supposed to be activated just as the door reaches the fully closed position to stop the further movement of the door. If it does not get activated at that point the door will try to open further but sence an "obstruction" and start opening again as a buildt in safety measure for protection against possible injury or damage to property.

How do you stop the door leaving a foot open at the bottom?


To stop the door in a partially open position, the button on the wall switch or remote should be pulsed when the door is opening from the fully closed position.

Hi the right hand hinge of the door has popped out whilst I was trying to move the oven using the door handle as leverage. The door is now wonky when closed as the hinged has popped out. Help!


All oven door typically lift off the hinges by design. If you open the door to what is referred as the broil position. You know when the door stops about 4 to 6 inches open at the top. Then do the following.

1. Lift the door up completely off the opposite hinge still in place and remove. Set the door aside carefully as if has glass window, you do not want to break.

2. Then set both hinges at the broiler stop position. If one is all the way in to door fully closed position pull it out with your hand or with pliers till it stops @ broiler position. If all the way down as if door was fully open, lift hinge until it stops at broiler position. CAUTION- THE HINGES ARE SPRING LOADED AND CAN SNAP BACK INTO FULLY CLOSED POSITION. You can use a heavy glove or if you have an oven mitten, that can work to protect your fingers. DO NOT GET YOUR FINGERS BETWEEN HINGE AND OVEN OR CAN PINCH FINGERS.

3. Now carefully lift the door over the hinges set at the broiler position. Careful not to bump them when doing so or can snap closed. If does, reset hinge to broiler position and repeat. Works best to hold door at angle that door is when in broiler position. Once you have them started evenly, you should be able to fully slide down back onto both hinges.

4. If one of the hinges no longer has spring tension you have to reattach the spring. You can usually access spring if needed by removing the bottom drawer.

Door goes down and when it stops at botton, it turns and goes back up ??? Need adjusting ..How can I adjust???


Adjust the position of the door by using the black and purple buttons. Black moves the door UP (open) and purple moves the door DOWN (close)
Setting the up position: 1. Press and hold the black button until the LED starts flashing slowly, then release. 2. Push and hold the black button until the door reaches the desired UP (open) position 3. Push the door control or programmed remote control. This sets the Up (open) position and begins closing the door. 4. Immediately when the door begins to close press and release the black or purple button. This will stop the door Setting the Down position: 5. Push and hold the purple button until the door reaches the desired DOWN (Closed) position. 6. Once the door is closed, If there appears to be too much pressure on the door, you may toggle the door back and forth using the black and purple buttons to reach the desired closed position. 7. Push the door control or programmed remote control. This sets the Down (closed) limit and the door should open.

I have a 1/2hp master mechanic door opener. when I close the door it goes the full travel down and then opens back up. i checked the eyes and everything was lined up. do you have any suggestions?


Look at the setting for "fully closed". it sounds like yours is set for slightly than the actual opening....So, the door reaches that location, and it thinks it hit an obstruction, which causes the door to open....While you are there, reset the sensitivity settings.

What I would do is back off the closed position setting so that the door stops an inch or two off of the ground, then adjust until the door is in the correct closed position...

You are correct on the "eyes" (infrared sensors) being lined up, if they were not, the door would not close at all.

2005 mazda 3 sunroof


H Kim -

The "gearbox" is unfortunately under the headliner with no easy access. If you are also experiencing a clicking sound when the motor is activated, the regulator track had slipped position and will need to be reset.

I have been through this problem twice now. The first time the motor / gearbox came loose from it's mounts, began slipping (click, click,click), very nasty sound. I remounted the motor with threadlock on the screws, but alas.. two years later (mine's 2006) it slipped again.. I don't know why yet, I need to drop the headliner once more and have a look. If you would like a copy of your FSM, drop me a line.

Here's the RESET procedure from the FSM, absolutely gospel, no other way to fix it:
Sunroof Motor Assembly Note: Note • If the guide is removed, initial position setting of the sunroof motor will be required. After installing the sunroof unit, perform initial position setting using the following procedure. 1. Press the TILT UP switch to fully tilt up the glass panel.
2. When the glass panel reaches the fully tilt up position, temporarily release the TILT UP switch and press it again for approx. 13 s continuously. Continue pressing the switch until the glass panel automatically stops at the fully tilt up position after reaching the mechanical lock position.
3. When the glass panel stops at the fully tilt up position, temporarily release the TILT UP switch, then press it again within 5 s and hold.
Note • Press the TILT UP switch continuously until the glass panel opens to the fully open position, returns to the fully closed position and then stops. 4. Release the TILT UP switch when the glass panel stops at the fully closed position.



ALSO, Here's the clearance adjustment specs for having the glass panel in the correct resting position:


GLASS PANEL ADJUSTMENT
1. Fully close the glass panel.
2. Measure the gap and height difference between the glass panel and the body.
3. Loosen the glass panel installation screws and move the glass panel to adjust.


Standard clearance a: 0.2-2.2 mm {0.008-0.08 in} b: 0 mm {0 in} 4. Tighten the screws.
5. Insert any available thin plastic card between the weatherstrip and the body, and verify that they are sealed. (There is resistance when the plastic card is moved.)


• If they are not sealed, perform Steps 3-4 and adjust again.

Cannot get chain drive to open or close position


What you need to do is adjust the down limit in the opposite direction of the arrow printed on the cover until the door stops before reaching the floor and the same with the up limit. Now that you have the door stopping in each direction you can tweak those adjustments until you have it right.

The door reverses back to open position instead of closing


SOUNDS LIKE A SENSITIVITY ISSUE UNHOOK THE DOOR AND TRY IT MANUALLY TO BE SURE IT DOESN'T BIND OR IS TOO HARD TO OPEN OR CLOSE.

IF ALL IS WELL CHECK THE SENSITIVITY SETTINGS ON THE BACK OR SIDE OF THE OPENER.

YOU WANT THIS SET AS LOW AS POSSIBLE AND STILL OPERATE THE DOOR WITHOUT REVERSING.

NOTE: THE FULL RANGE OF ADJUSTMENT IS ONLY ABOUT 3/4 TURN SO MAKE A VERY SLIGHT ADJUSTMENT AND THEN TRY IT AGAIN.

HOPE THIS HELPS
