3. Check the Power Supply

An electric blanket comes with a charger and power cord. You have to check these accessories. Maybe they have stopped working. Connect the charger firmly to the power cord and to the outlet.

Moreover, make sure your electric supply outlet has current and power. Try plugging the blanket into a different outlet. Try another charger.

Also, examine the power cord. It should not be damaged, exposed, or frayed out. The blanket must be receiving adequate power.

4. Examine the Heating Wires

An electric blanket has multiple heating wires. They are responsible to heat up your blanket. You have to test all these wires.

Tighten them firmly to ensure proper power supply. If any of the wires are faulty or damaged, replace them. Take help from a Multimeter to test the wires.

5. Check the temperature sensor

A thermostat or temperature sensor regulates the amount of heat in the blanket. If the thermostat starts malfunctioning, your blanket will not heat properly.

You have to cut open the blanket to check this component. Unfortunately, some brands do not offer replacement parts. Hence, you have to replace the whole blanket.

6. Check the Controller

There can be a problem with the controller. Check whether it is displaying everything normally or not. Moreover, you can test the controller using a Multimeter. Check for continuity and voltage.

Open up the controller through a screwdriver. Examine it from the inside and ensure that all wirings are fine. You have to replace the controller if it is not working.

However, before that do try all the troubleshooting tricks given in this article. Your blanket can last longer if you maintain it properly.
