The reason why the freezer does not run

1. Power failure of power grid, fusing of fuse, tripping of automatic air switch, action of leakage protector, power switch of this machine not closing, timer not entering the running position of the whole machine, etc, that is, the commercial freezer is actually not connected to the power supply.
2. The power supply voltage is too low, the starting torque of the motor is small, the motor cannot rotate, the overload protector acts, and the power supply circuit of the whole machine is cut off.
3. The battery power in the remote control switch is exhausted and the positive and negative poles are reversed, so the remote control switch does not work and the commercial freezer does not receive a boot command.
4. The set temperature of the freezer is improper. For example, the set temperature is higher than or equal to room temperature during refrigeration, and the set temperature during refrigeration is lower than or equal to room temperature.
5. If the running freezer is turned on immediately after shutdown, there will be 3min delay protection and the freezer will not start immediately.
6. The ambient temperature is too high or too low. For example, the outdoor temperature during refrigeration exceeds 43℃, and the outdoor temperature during heat pump heating is lower- At 5℃, the internal protection device will automatically cut off the power supply of the machine.
