I used too much force when de-icing the refrigerator, which broke the pipe and exposed the air.

Haha, the loss is not small. Do not turn on the refrigerator again. Before repairing, seal the leaking point to prevent foreign matter and more moisture from entering the pipe. Generally speaking, if the leakage point is not too big, you can use the method of sealing, which is to use AB glue and fiber to apply it in layers. It is very effective. Be sure to clean it. If the leakage point is too big, you can remove one section and choose another section, use Rock ring and AB glue or welding. This is also the most economical method. I have repaired many refrigerators using this method, and it works very well. It is best to send it to the repair department. They have better methods. Do not repair it yourself to prevent the failure rate from increasing and causing the refrigerator to be scrapped. The maintenance cost depends on the location, but it is generally between 100 and 200, which is not too expensive. Hope my answer helps you.
