What You'll Learn
Check the power supply
If your Biddeford electric blanket is not working, it is important to check the power supply. Firstly, ensure that the blanket is switched on at the power switch on the thermostat. The thermostat can be used to turn the blanket on and off, so make sure it is set to your preferred temperature. If the thermostat is working, turn it up to its highest setting and wait for five minutes to see if the blanket warms up.
Secondly, check that the electric blanket is plugged in. Make sure the power cable is connected directly to an outlet and not to an extension cord or power bar. Check that the outlet is switched on. Follow the power cord from the outlet to the blanket, ensuring that each connection is clipped in place. The plastic joints in the power cable can sometimes come loose, so make sure they are secure.
If the blanket is still not working, there may be an issue with the power cord or the blanket itself. Check for any visible damage to the power cord or the blanket. If the power cord is damaged, it may need to be replaced. If the blanket is damaged, it may be a fire hazard and should be replaced.
In some cases, the problem may be caused by a faulty fuse or resistor in the blanket. Biddeford electric blankets have a white thermal fuse that can fail. If the fuse is blown, it will need to be replaced. You can purchase a replacement fuse with part number SM110A1, which will take a little more heat before it blows. If the resistors in the blanket circuit are burnt or smoked, you may need to trace the paths from the resistors to identify possible faults.

Check the thermostat settings
If your Biddeford electric blanket is not working, it could be due to incorrect thermostat settings. Here are some troubleshooting steps to check the thermostat settings:
First, ensure that the electric blanket is switched on at the power switch on the thermostat. Biddeford blankets have a convenient feature that allows them to be turned on and off directly from the thermostat, so you don't need to get out of bed to unplug it from the outlet. Check if the power switch on the thermostat is in the "on" position.
Next, adjust the thermostat to your desired temperature. Turn the thermostat up to its highest setting and wait for approximately five minutes. If the blanket is functioning correctly, you should feel it warming up. Once it feels warm, you can turn the thermostat down to your preferred temperature setting.
If the blanket still doesn't seem to be heating up, there could be an issue with the thermostat itself. Check for any visible damage to the thermostat or the power cord connected to it. If you notice any signs of damage, it may be best to contact Biddeford customer support or a qualified technician for further assistance.
In some cases, the issue could be related to the internal components of the thermostat, such as resistors or fuses. If you are comfortable with electronics, you can try checking the resistors for signs of burning or smoking. Sometimes, the thermal fuse in the blanket may blow, causing the blanket to stop working. If you suspect a problem with the internal components, it is recommended to seek professional advice or contact Biddeford support for guidance on repairs or replacements.

Check for visible damage
If your Biddeford electric blanket is malfunctioning, it is important to check for any visible damage. Start by examining the blanket itself for any signs of wear and tear, such as loose wires, frayed edges, or exposed heating elements. Pay close attention to the areas where the blanket connects to the power cord, as these connections can sometimes work loose with normal movement in the bed.
Next, carefully inspect the power cord for any visible damage. Check for exposed wires, cracks, or signs of overheating. Make sure that the power cord is plugged in and that each connection is clipped in place. A loose connection could not only be a safety hazard but also interfere with the proper functioning of the blanket.
If the blanket and power cord appear intact, it's time to check the power outlet. Ensure that the power cord is plugged directly into a wall outlet, as the use of extension cords or power bars is not recommended. Check that the outlet is functioning properly by plugging in another device or a lamp to confirm that it is switched on and providing power.
In some cases, the issue may lie with the controller or thermostat. Examine the controller for any signs of damage, such as a rattling heating switch or loose wires. Check the settings on the controller to ensure that the blanket is turned on and that the thermostat is set to your desired temperature. Adjust the settings and wait a few minutes to see if the blanket starts to warm up.
Finally, if your Biddeford electric blanket has a removable cover, inspect the inside of the cover for any signs of damage. Check for any melted or burnt areas, particularly around the heating elements. If you notice any visible damage to the blanket, power cord, or controller, it is important to discontinue use and contact the manufacturer or a qualified technician for further guidance or repairs.

Replace the thermal fuse
If your Biddeford electric blanket has stopped working, it may be due to a faulty thermal fuse. The thermal fuse is a safety feature designed to prevent the blanket from overheating. When the fuse blows, it cuts off the power to the blanket, preventing it from catching fire.
To replace the thermal fuse in your Biddeford electric blanket, follow these steps:
- Unplug the blanket from the power outlet and lay it out flat on a table or clean surface.
- Locate the controller or control box of the blanket. It is usually a small, rectangular box attached to the blanket with a power cord protruding from it.
- Using a screwdriver, open the controller by removing the screws that secure the cover in place. Be careful not to lose the screws, and set the cover aside.
- Inside the controller, you will see various electronic components, including the thermal fuse. The thermal fuse is typically a small, white, cylindrical component with two metal caps on either end. It may have THF or "SM110A1" printed on it.
- Carefully desolder or clip one end of the thermal fuse to detach it from the circuit board. You may need to use a soldering iron or a small screwdriver for this step.
- Take note of the orientation and position of the thermal fuse, as you will need to install the new one in the same way.
- Obtain a replacement thermal fuse with the same specifications, such as the SM110A1 from Amazon, which is recommended for Biddeford blankets.
- Install the new thermal fuse by soldering or clipping it into the same position as the old one, ensuring it is securely connected to the circuit board.
- Reattach the controller cover and secure it with the screws you removed earlier.
- Plug the blanket back into the power outlet and test it by turning it on and adjusting the thermostat. Ensure it is functioning properly and heating up as expected.
By following these steps, you can replace the thermal fuse in your Biddeford electric blanket. Remember to exercise caution when working with electrical components, and if you are unsure or uncomfortable with any part of the process, it is best to seek professional assistance or consider purchasing a new blanket.

Check the controller for faults
If your Biddeford electric blanket is not working, there could be a fault with the controller. Before attempting any repairs, make sure the blanket is unplugged. Then, check for any visible damage to the controller or power cord. If there is any damage, do not use the blanket and consider contacting customer support for a replacement.
If there is no visible damage, the next step is to check the fuses. Biddeford electric blankets have two fuses: a standard fuse and a white thermal fuse. The thermal fuse is the component that most often fails. If the thermal fuse has blown, simply replace it with a new one. You can purchase a replacement thermal fuse with part number SM110A1 from Amazon.
If the fuses appear to be intact, the problem could be related to the resistors or other components in the controller. In this case, it is recommended to use an Ohmmeter to measure the resistance of the circuits in the blanket. Caution should be exercised when dealing with electrical components, and it may be advisable to seek assistance from a qualified technician.
In some cases, it may be more cost-effective to replace the entire controller rather than attempting to repair individual components. You can purchase a new controller directly from Biddeford or from select retailers.
