If the equipment installed with the defrost heating tube does not work properly, we can check the following items:
1. Check whether the connection wire of the defrosting heating pipe is broken or not connected correctly.
2. Check whether the defrosting electric heating tube is burned or leaking.
3. Check whether the terminals of the air cooler junction box leakage or not.
4. If you check that there is no problem for the above, and it is not a problem of cold storage. If the refrigeration is normal, then directly connect the total three-phase electric switch to the cold storage electric box, do not connect any other item.
