Replacing the window reader: when the shutter is locked and does not respond to the pen

A real-life case: how I unlocked the mechanism and replaced the main drive for one exit.

The reducer (main drive) is a window fittings device that transmits power from the handle to the shutter mechanism, opening, closing and dropping the shutter. When the reducer fails, the shutter can lock, stop responding to the turn of the handle or start to rotate.

I, Dmitry, a master in the repair of plastic windows in Minsk. I have been working since 2003, I have passed through more than 9 800 windows.

The main thing is:If the pen doesn't turn or it's not turning inward, and the shutter is intentionally on, it's almost always a reducer. You can't unlock it by force: you can break the pins, you can swallow the traction, and in the worst case, you can damage the profile.
Don't try to force open the locked door.Every rough move is an extra load on the pins, the bars, the loops and the pen, and the details that could have been saved will be out of order, and the bill will go up in numbers.
Replacement of the reducer (basic drive)
120 roubles.
The window, balcony door, 150 rubles, including unlocking, replacing, lubricating and adjusting.

The problem is a faulty reader.

I was approached with a classic situation: the window sill stopped opening. The handle either didn't turn at all or it was turning without resistance, but the mechanism didn't work. The cause was the main drive broke. The mechanism was locked, and the sill was locked in one position.

Signs that the gearbox is in trouble:The handle does not rotate or rotate in the center of the handle; the lock is in one position; clicks or screams are heard inside the center of the handle; when the handle turns only part of the bolts is activated.

How I replaced the speaker

It was a difficult task, but it was quite feasible.

1
Dismantling the glass package Carefully removed the sticks, pulled out the glass packets — to gain free access to all the furniture elements, including the locked-in reducer.
2 of the
Unlocking the mechanism In the weakest place (where the crease was slightly off the frame) he pulled the crease to reach the locking chaff.
3 of the
The return of mobility to the furniture With a few light, accurate strikes on the chappé with a special instrument, the whole mechanism was brought into motion.
4 of them
Replacement of the reducer I've dismantled the old, broken drive, installed a new one compatible with this system of the gearbox, checked all the traction and the traction of the clutch with the answering plates.
5 of them
Reverse assembly He put the glass pack in place, secured the sticks.
6
Lubrication and adjustment He worked all the moving parts with silicone lubricant, adjusted the crimp and geometry of the crease.

The whole thing took about two hours.

The result

When the drive is replaced, the shutter opens again easily and smoothly, without any strikes or other sounds. The handle rotates with normal force, the window closes tightly. The customer is pleased with the result — and this is a good example of how even a difficult break can be solved in one go with a professional approach.

Why it's important to change the gearbox on time

  • ✔ What is it? Security.A locked door can cause injury when you try to open it, especially if the window is high.
  • ✔ What is it? Keeping the window.A faulty drive creates an uneven load on other pieces of furniture -- the racks, the planks, the loops -- they go out of order after the gearbox.
  • ✔ What is it? It's a comfort.The correct fitting is a light opening, a tight closing, no sliding.

From the practice of a master

From the practice of a master

The window stopped opening, the handle didn't turn, the mechanism didn't work, the reader broke down, the unit was locked in one position.

He removed the sticks, pulled out the glass packets — to access the entire furnishings. He pushed the shutter back to the place of greatest weakness, reached the spell-bound shutter, with a few precise strikes with a special tool restored the mechanism to mobility. He replaced the broken reductor with a new one compatible with this system.

The work is easy to open, without any strangulation or noise.

Frequently Asked Questions

Can we fix the old gearbox?
The reducer is a complete mechanism, which is easier and more reliable to replace with a new one when broken. Replacement costs less (120 rubles window / 150 rubles balcony door) and guarantees long work, and attempts to repair the old one almost always end in a repeated breakdown.
How much does it cost to replace the speaker?
The cost includes all the work: unlocking, dismantling the old one, installing the new one, lubricating and adjusting. The exact amount I call after a free review — before the work starts. It is much cheaper than the full one.Replacement of the furnishings(270–300 rubles) or replace the crevice.
How do you know if the reducer's broken?
The main signs: the handle does not turn (or does not turn, but the shutter does not react), the shutter is in one position, clicks or screams are heard inside the mechanism.
Can I unlock the lock myself?
I'm not suggesting it, unlocking requires a special tool and a precise understanding of where and how much effort to put in the impact, and the force here is working against you: it's easy to break the plug, bend the pull, damage the profile or the pen.
