1. Check the power plug: First, check whether the power plug and socket of the freezer are in good contact. If the plug or socket is loose or rusty, it should be plugged in again or derusted.
2. Check the switch: Secondly, check whether the power switch of the freezer is turned on. If the power switch is not turned on, the power light will not light up.
3. Check the power cord: If there is nothing wrong with the switch, check whether the power cord is damaged or broken. If the power cord is damaged or broken, it needs to be replaced.
4. Replace the power light: If the power cord is normal, check whether the power light is damaged. If the power light is broken, you need to buy the corresponding power light to replace it.
5. Check the power board: Finally, if the above methods can't solve the problem, you need to check whether there is a problem with the power board. If the components on the power board are burned or damaged, the power board needs to be replaced.
In short, if the power light of the freezer is not on, we should start with the socket and plug to check whether the power switch is turned on, and then check whether there is any problem with the power cord, power light and power board, check them one by one, find out the problems and carry out maintenance or replacement.
