Why is the electric blanket not heating up?

For friends in the south, it is important to always have electric blankets in winter. After all, compared with houses in the north, houses in the south are not equipped with heating. In the cold winter weather, with the help of electric blankets, you can also feel the warmth in bed. But the newly bought electric blanket doesn't get hot at all when plugged in. What's going on? Is it a fake? Today I will analyze the specific reasons for this situation.

The heating wire and indicator light of an electric blanket form a parallel circuit. When you connect the electric blanket to a power source, the current passes through the indicator light and the heating wire of the electric blanket respectively. If only the indicator light is on, it means that the heating wire of your electric blanket is broken and a circuit cannot be formed, so the electric blanket cannot generate heat.

Sometimes the electric blanket becomes damp and affects its normal operation, so it does not heat up.

Therefore, you should be careful when using electric blankets. If the electric blanket is dirty, you cannot soak it in water or rub it. You can only lay the electric blanket flat on the board and wipe it clean with a soft brush or dip it in some diluted detergent to gently wipe the dirty surface, then dip it in clean water to brush it, and then place it in a ventilated place to dry. Be careful not to turn on the power to dry it.

Electric blankets used on soft beds such as sofa beds and steel beds must be foldable electric blankets. What is usually sold on the market is a linear electric blanket, which is only suitable for use on a harder bed and cannot be used on a soft bed, otherwise the heating element may break easily and cause an accident.

When storing electric blankets, they should be dried first and then rolled into a round shape and bagged for storage. Be careful not to fold them into multiple layers and do not squeeze or press them heavily to avoid damaging the blanket components.

Scientific method and steps to use electric blanket

1. Connect the power supply

Connect the plug of the electric blanket to the socket. There will usually be an indicator light. If the indicator light is on, then there should be no problem with the circuit.

2. Switch

On and off, this is a function that every electric blanket has.

You can open it and wait for 3 to 5 minutes to see if there is any heat coming up.

Generally, you should check the switch carefully when you just buy it.

Finally, try closing it and it will work.
