Doors that move differently after heating require an assessment of their seating and condition of parts. Do not try to restore closure with more force while the device is operating. After cooling, compare the frame and opening with the previous state and the instructions of the specific set.
Separate the frame from the door panel
Vitcas oven doors with glass and thermometer have specified frame and opening part dimensions. Check what was measured during installation. The external product dimension does not have to describe the same place as the opening prepared in the wall.
Inspect the edges, hinges, and adjustment elements without fire. Note the point where the door catches and change in position. Do not accidentally grind parts before determining whether the problem concerns the frame, the joint, or the mechanism itself.
Compare the installation with the design
The connection to the wall should meet the device requirements, including the intended behavior of the metal during heating. Outdoor Oven Cement is used for the described refractory connections. Mortar does not confirm the correctness of a frame bricked in any way.
Check whether the finish has not closed the space needed for movement or removal of parts. When replacing a seal, for example stove rope, select the size according to the specific part. A thicker gasket may change the pressure instead of removing the cause of sticking.
Keep a record before the repair
Take photos of the hole, frame, and mounting points with a visible scale. Compare the condition before and after the planned assessment. If there is deformation or movement of an adjacent brick, the problem requires diagnosis before further use.
After performing the proper repair, maintain the required preparation steps. Check again while cold, without forcing closure. The system record allows you to evaluate the result instead of returning to another random increase of the clearance.
