When Your Casement Window Won’t Budge: Understanding Crank Mechanism Failures and Your Repair Options

Few things are more frustrating than a casement window that refuses to open on a beautiful day or won’t close when storm clouds gather. It is possible that the casement window crank can stop working. This can happen for a variety of reasons. The crank handle itself can be stripped, and the gears inside may no longer be gripping the gear mechanism properly. Understanding the common causes of casement window crank failures and knowing your repair options can save you time, money, and the headache of dealing with a malfunctioning window.

Common Signs Your Casement Window Crank Needs Attention

If your window crank handle just spins when it’s turned, or it can’t pull in the sash far enough to engage the lock, chances are the gears are stripped and it’s time for a new crank mechanism. Other warning signs include if the window crank handle simply spins when you turn it or you can’t use the handle to pull in the sash so the device locks, then the problem could be that the gears are stripped.

Professional window repair technicians often see several recurring issues with casement window cranks. Sometimes rust and maybe even dirt and grime can build up in the gear mechanism, causing them to stick and even fail. If unlubricated for several seasons, the gears can even become stripped. Additionally, the gears strip out when the handle is over-torqued when either opening or closing the window.

Troubleshooting Gear Mechanism Failures

Before assuming you need complete hardware replacement, there are several troubleshooting steps worth trying. If the crank mechanism appears to be in good condition, try turning it with your hand or an adjustable wrench. If it’s difficult to turn or doesn’t turn at all, the issue may be due to a lack of lubrication.

If the crank mechanism is difficult to turn or doesn’t turn at all, applying a lubricant can often resolve the issue. Turn the crank mechanism several times to work the lubricant into the gears and moving parts. However, if the window still doesn’t operate smoothly, it may be necessary to replace the casement window crank. If lubricating the crank mechanism doesn’t resolve the issue, you may need to replace the casement window crank.

Understanding Hardware Replacement Options

When repairs aren’t sufficient, replacement becomes necessary. If the crank handle has missing teeth, just replace the handle, but if the operator itself is damaged, replace the entire device. The challenge often lies in finding the correct replacement parts. The hardest part, you’ll find, in replacing a stripped window crank is locating the exact match of the parts. You don’t want to be stuck with a new crank that you can’t install, so do your due diligence beforehand and track down an appropriate replacement.
