THE SHORT ANSWER
Stop turning the crank when it resists or spins without moving the window. From indoors, note whether the moving panel stops short, rubs the frame or reaches the closed position but will not lock. Those observations help support assess the operator and alignment. Do not use the lock or extra crank pressure to force it shut.
Before you try anything
Keep children away from an unsecured opening. An insect screen will not prevent a fall. Stay on the indoor floor without leaning out, climbing or pushing the glass. Stop for cracked glass, a loose sash, unstable hardware or wind-driven movement. Do not remove a screen, hinge, operator arm or opening-control device to obtain closure.
Before you begin
For an outward-opening, crank-operated casement window. The sash is the moving framed-glass panel; the operator is the mechanism driven by the crank. Sliding, hung, awning and powered windows use different arrangements. Covers observation and service preparation, not hardware adjustment or sash removal.
Use an existing receipt, manual or safely visible label for the brand, series and approximate age. Record recent installation or repairs and where the panel stops. A photo from inside can show the gap without another opening attempt.
In a rental, report the problem to your landlord or property manager before making repairs. Building rules and local requirements vary.
Work through the checks
- 01
Check for a product-specific safety notice
A February 26, 2026 CPSC recall covers certain opening-control devices on Andersen 100 Series casement windows. Affected windows must remain closed and locked pending the authorized repair. Read the Andersen opening-control-device recall and ask the manufacturer to confirm coverage. If yours cannot close safely, keep people away and report that immediately; do not force it to comply.
- 02
Describe what the crank already did
Record resistance, free spinning or visible looseness observed during normal use. Andersen lists these among operator-related symptoms, but they do not identify a replacement for every window. Stop repeated turning and leave covers and screws in place.
- 03
Record the gap and contact point
From indoors, note where the sash approaches or touches the frame. Andersen identifies rubbing and failure to close or lock as possible alignment concerns on its A-Series casements. This does not establish that your hinges need the same adjustment. Do not lift the sash by hand or move a hinge.
- 04
Separate closing from locking
Tell support whether the sash remains visibly open or reaches its usual closed position while the lock resists. Report both if unsure. Do not pull the panel inward with the lock or attach a cord, clamp or improvised handle. An unsecured window needs prompt attention.
- 05
Identify the unit before arranging parts
Andersen operators vary by series and age. Give the installer or window-service provider the product details, observed movement and recent changes. Ask for an assessment before ordering a crank, operator or hinge kit. Renters should contact property maintenance.
What your result means
These observations help choose a next step. They do not confirm a diagnosis.
| What you notice | What it tells you | Next step |
|---|---|---|
| The crank turns but the sash does not follow | The operating mechanism needs assessment | Stop repeated turns and contact support. |
| The sash rubs or leaves an uneven gap | Alignment may be involved | Record the contact point; leave adjustment to service. |
| The sash reaches closed but will not lock | Security and locking need attention | Arrange prompt service without forcing the lock. |
| A recall matches the opening-control device | Special instructions apply | Follow the manufacturer recall route. |
| Glass, sash or hardware is unstable | Ordinary observations are no longer appropriate | Keep people clear and obtain urgent qualified help. |
Know what happens next
Check the outcome
After appropriate repair, confirm that normal operation and locking follow the exact product instructions without extra force. Ask the technician to confirm the opening-control device and any required emergency-opening function. A window that closes once does not establish that a recurring alignment or hardware fault is fixed.
When to call a professional
Get prompt help when the window cannot be secured, rubs repeatedly or has damaged hardware. Treat a loose panel or broken glass as an immediate access hazard. Do not seal, screw or glue a window shut as a substitute for repair, particularly where it is needed for escape.
Take useful notes with you
A short record makes it easier to explain the problem to a landlord, technician, or responder. Do not collect notes during an emergency.

Common questions
Does a freely spinning crank mean I only need a new handle?
It does not select the repair by itself. Handle and operator designs vary; identify the unit and describe the symptom to support.
Can I adjust the hinges using another model's guide?
Use guidance for the exact unit and appropriate service help. The cited Andersen A-Series procedure is not a universal casement adjustment.
Is the screen enough protection while I wait?
No. Screens are for insects and do not retain a child or adult. Keep people away and arrange prompt help to secure the opening safely.
