In this way, it is performed up and down simultaneously until the ice melts completely and flows out of the discharge valve. Then close the valve, fill with hot water, wipe the external dirt, find the crack site.

Therefore, when the freezing is not serious, the machine will generally not be frozen. Even if the cracking phenomenon occurs, it will only occur in weak places. Once the cracking phenomenon occurs, the pressure in other parts will be greatly reduced, and generally will not be Cracked. Therefore, once the body is frozen, it can only be frozen.
3, the machine is frozen, cracks can not be on the outside, after the external inspection, you can loosen the oil sump drain bolts, if water seepage, it is necessary to let go of the oil, remove the oil pan, carefully find the leak Parts.
