If you see an 'FF' error, this could mean that a problem has been detected. Try unplugging the blanket for several hours and then plugging it back in. If the error code is 'E', this could indicate a loose wire, or that the blanket is tucked in incorrectly, causing the current to not flow through the blanket.
If your electric blanket is not working, it could be due to wiring problems. Check the connector on the blanket and make sure it is plugged in correctly. If the connector is plugged in correctly and the blanket is still not working, there may be a broken wire in the blanket. You can also check for broken wires by using a voltmeter to check the voltage and resistance across the blanket's prongs. If there is zero resistance across 1 and 3 of the blanket lead, this could indicate a broken wire.
Control unit faults are another common issue with electric blankets. If you have two controllers, you can try swapping them to see if the issue is with the controller or the heater element/wiring. If you are comfortable with electronics, you can try replacing the control unit with a suitable part from the manufacturer or an electronics store.

Fix loose connections: A simple adjustment might solve the problem
If your electric blanket is not working, it could be due to a loose connection between the plug, the cord, and the controller. Before giving up on your blanket, check the connections.
Step 1: Unplug the blanket
Before starting any repair, ensure the blanket is completely disconnected from any power source to prevent the risk of electric shock.
Step 2: Inspect the plug and cord
Look for any signs of damage or wear on the plug and cord. Ensure they are intact and securely connected without any loose parts.
Step 3: Examine the control unit
Open the control unit and look for any loose connections or visible damage inside. Use a multimeter to check for continuity in the wiring from the plug to the control unit and from the control unit to the blanket. A disruption in continuity could be the reason for the ‘P’ error.
Step 4: Tighten the connections
If any wires inside the control unit are loose, tighten them or solder them back into place if necessary. If wires have come loose from their terminals, re-solder them to ensure a secure connection.
Step 5: Test the blanket
Reconnect the power and test all settings on the blanket to ensure it heats uniformly and safely.

Insulate repairs: Use electrical tape or tubing to insulate repaired sections
Before attempting any repairs on your electric blanket, it is crucial to ensure that it is completely disconnected from any power source to prevent the risk of electric shock. Electric blankets can be complex, and many issues can be resolved with simple fixes. However, safety comes first, so if a problem seems beyond your skill level, seeking professional help is advisable.
Once you have identified the faulty section of the electric blanket, you may need to open the fabric casing around the wire to make a more detailed inspection and repair. If you find a break in the wire, carefully solder the broken ends together, ensuring that the solder joint is strong and insulated to prevent any short circuits.
Now, to insulate the repaired section of the wire, you can use high-quality electrical tape or heat-shrink tubing. Electrical tape is a simple and effective way to insulate wires and protect them from moisture and abrasion. When using electrical tape, start by wrapping the tape around the wire in a spiral pattern, overlapping each layer slightly to ensure complete coverage. Stretch the tape slightly as you wrap to improve adhesion and ensure a tight seal. Continue wrapping until you have covered the entire repaired section, plus a small area on each side of the repair for added security. Finally, press down on the tape to smooth out any air bubbles and ensure a secure bond.
Alternatively, you can use heat-shrink tubing to insulate the repaired section of the wire. Heat-shrink tubing is a flexible, insulating material that forms a tight seal around wires when heated. First, determine the diameter of the damaged wire using a ruler or measuring tool. This measurement will help you choose the correct size of heat-shrink tubing. Slide the tubing onto one end of the wire and feed it through until it covers the repaired section and a small area on each side. Gently wipe away any dirt or grime on the wire to ensure a clean surface for the tubing to adhere to. Once the tubing is in place, apply heat evenly using a heat gun or a micro torch. The tubing will shrink and conform to the shape of the wire, providing a secure and insulated finish. Allow the tubing to cool before moving the wire back into its original position.
After insulating the repair, use a multimeter to check that the circuit is complete and the blanket is functioning correctly. Then, secure all wires and ensure that no loose wires are exposed. Finally, reconnect the power and test the blanket on all settings to ensure it heats uniformly and safely.
