commercial refrigeration door seal and liner disassembly, diagnosis and maintenance

1. The door seal and liner disassembly instructions, turn the door seal up Once the fixing screws are exposed, the fixing screws are removed one by one with a screwdriver, and then the door liner can be removed and a magnetic door seal can be removed from the door liner. When installing, put the door seal around the door liner and make a pair of the original fixing holes. Fix it with screws on the upper side. Tighten the screws at the diagonal position and install other screws. Pay attention to the flatness and position of the door seal before tightening the screws.

2. Diagnosis and repair of the door seal. The deformation of the door seal will cause poor internal sealing of commercial refrigeration, long start-up time, short downtime, and the freezer door cannot be opened due to freezing. Generally, hair dryer can be used for shaping. But pay attention to the distance between the hair dryer and the door seal and the heating temperature, so as to avoid the door seal from being damaged by the high temperature. If the four corners of the door seal are not well sealed, the corner door seal can be turned up and filled with an appropriate amount of sponge-like soft plastic. If the door seal becomes hard and aging, try to repair it first. If it cannot be repaired, consider replacing it with a new one. The repair method of the door seal is aging: use a knife to cut the adhesive at the corner of the door seal and pull out the plastic magnetic strip (be careful not to break) Remove the seal and soak it in water at about 60°C for about 5 minutes. Pinch both ends of the seal with your hands and straighten it out. Put it on a flat table or glass plate to make the door seal flat (if the effect is not good once, please repair it once. If the latter seal is slightly longer than the original one, you can cut off the excess part.) Use a heated hacksaw blade to stick the seal block firmly together. When installing the magnetic strip, the suction side should face the commercial refrigeration body.

3. Diagnosis and repair of the door liner. The damaged form of the liner is rupture. The detachable type should be replaced, and the non-detachable type should be glued. The sticking method is: according to the degree of cracks, put an appropriate amount of acetone in a glass bottle, and then process the plastic into small particles and put it into the acetone bottle. After the acetone dissolves all the plastic, it becomes a milky white bouncy liquid for use; Wipe clean the rupture of the inner liner of the refrigeration door. After it is naturally dried, turn on the power to cool the commercial refrigeration for 1 hour. The above-mentioned self-made glue dissolved in the rupture is not allowed to penetrate into the seam. After drying, the commercial refrigeration can be used normally .
