If the equipment installing the defrost electric heating tube does not work properly, we can check the following items:
1. Check whether the connecting wire of the defrost electric heating pipe is broken and whether it is connected incorrectly.
2. Check whether the defrost electric heating tube is burned or leaked.
3. Check whether there is leakage of the terminal post in the junction box of the air cooler.
4. If you check that there is no problem in all places, make sure that it is not a cold storage problem, but still connect the defrost electric heating tube and jump to the total
Gate, refrigeration is normal, then directly from the total three-phase electric gate to the cold storage electric box, do not connect anything in the middle, bypass the total
The gate, the cold storage electric box itself has three opens, it's okay.
