Tianchi Technology: If you notice that the ice machine chassis door will not seal, it is likely to be due to gasket damage. This can cause air to escape from the device, causing internal temperature fluctuations that can block your food and beverages.
When replacing a genuine refrigerator liner, it is very important to find the serial number and model number. Both can help you determine the date of manufacture to find the right gasket for your device.
Leveling is also a common problem that can cause the door to fail to close properly. Place a level on top of the unit and inspect it from side to side and from front to back. Loosen the bolts on the casters that need to be lifted and insert a suitable amount of spacers on each side to adjust the height (do not exceed three washers per side).
