The aluminum alloy window is stuck. What should I do?

Methods: Replace the new pulley, and pay attention to the light action when pushing and pulling at ordinary times. This is also a place to pay attention to, because pulleys are prone to problems. The pulleys for doors and windows I bought before were not broken, but fortunately I went to Fu Xuan doors and windows this time and bought them from German. Good quality, smooth push and pull.

Reason 2: the dust or garbage in the push-pull groove has not been cleaned for a long time, causing blockage.

Methods: Use a vacuum cleaner to remove the dust accumulated on the top of the groove and door seal, then wipe it with a wet rag and clean it at ordinary times.

Reason 3: There is too much water vapor in the environment, or there is water in the door frame and chute that cannot be treated in time.

Methods: Wipe the accumulated water with a rag in time to keep the environment dry.

Reason 4: The aluminum alloy door frame is deformed and sunken inward.

Method: Just break it straight with pliers, pay attention to normal maintenance, and don't stand on it. Pay more attention to the materials when buying. My doors and windows in Fu Xuan are all national inspection-free aluminum, which is why they are so durable.

Reason 5: the friction increases after too long use.

Method: Add a little engine oil or a layer of wax oil for lubrication.

Reason 6: The link between the pulley and the door is loose.

Methods: Tighten the screws, pay attention to maintenance at ordinary times, and don't shake on both sides when pushing and pulling.
