Repairing Aroma Hot Plate Switch: A Step-By-Step Guide

If your Aroma hot plate switch is faulty, you may need to replace it. Before replacing a part in any electrical appliance, ensure that the appliance is unplugged from the mains. You will need screwdrivers, a blanket or mat to protect the product, and a multimeter to check the heating element. First, remove the control knob and the mounting screw, then remove the screws under the panel and push it to the side to unhook it. Next, take a photo of the faulty switch connections, and transfer the wires one at a time to the correct terminal on the new switch. Finally, refit the screws, heat shield, and control knob, and test the repair.

How to Repair a Hot Plate Switch

Identify the fault: Check the heating element and control switch

If your Aroma hot plate has stopped working, it could be due to a faulty heating element or control switch. To identify the fault, you can perform the following checks:

Checking the Heating Element:

• Disconnect the hot plate from the power supply.
• Remove the hot plate's control knob and unscrew the plate to access the heating element.
• Inspect the heating element for any signs of damage, such as burnt or melted areas.
• Use a multimeter to test the heating element for continuity. If it tests positive, the element is functional, and the issue is likely with the control switch.

Checking the Control Switch:

• With the hot plate still open, locate the control switch, which is usually held in place with screws.
• Remove the screws and carefully inspect the switch for any signs of damage or wear.
• Pay close attention to the switch contacts, as faulty or damaged contacts can cause the cooker to blow fuses.
• If the control switch appears damaged or faulty, it will need to be replaced.

By performing these checks, you can identify whether the fault lies with the heating element or the control switch, allowing you to take the appropriate repair steps. Remember to exercise caution and wear safety gloves when working with electrical appliances.

Disconnect power: Ensure appliance is unplugged before attempting any repairs

Before attempting any repairs on your Aroma hot plate, it is crucial to prioritise your safety by ensuring that the appliance is completely disconnected from its power source. Here are detailed instructions to guide you through this important step:

Disconnect Power:

First and foremost, locate the power source of your Aroma hot plate. It is most likely connected to an electrical outlet or wall socket. Proceed to unplug the appliance from the power source. It is imperative that you do not skip this step, as electricity can cause serious harm or injury if not handled with caution.

Ensure Appliance is Unplugged:

Once you have unplugged the hot plate, take a moment to double-check that it is indeed disconnected. This step is crucial, as you will be working with internal components of the appliance, and any live electrical connections can pose a significant safety hazard. Visually verify that the power cord is completely removed from the power source.

Safety Precautions:

Even after disconnecting the power, it is important to exercise caution. If your hot plate has been in use recently, allow it to cool down before proceeding with any repairs. Additionally, put on a pair of safety gloves to protect your hands from sharp edges that may be exposed during the repair process.

Prepare for Repairs:

Now that your Aroma hot plate is safely disconnected from the power source, you can proceed with the necessary repairs. Remember to have the appropriate tools and replacement parts ready before beginning any work on the appliance. Refer to repair guides or manuals specific to your Aroma hot plate model for detailed instructions on the repair process.

Safety First:

Always keep in mind that your safety is paramount. If at any point you feel uncomfortable or unsure about performing the repairs, it is best to consult a qualified technician or repair service. They will have the expertise and experience to handle the task safely and effectively.

By following these steps, you can ensure that your Aroma hot plate is safely disconnected from its power source, allowing you to proceed with repairs or maintenance tasks without the risk of electrical hazards.

Remove the control knob: Unscrew and take off the control knob

Before beginning any work on your appliance, it is important to disconnect it from the mains to ensure your safety. It is also recommended to wear suitable safety gloves to prevent injury from sharp edges.

Now, to remove the control knob, start by unscrewing the screws that hold the hot plate in place. Once the hot plate is removed, identify the selector switch that needs to be replaced. It is advisable to remove the corresponding control knob as well. This will give you access to the switch, which is also held in place by screws. Remove these screws to detach the switch.

The control knob is typically attached to the selector switch shaft. To remove it, simply pull or twist it off gently. Be careful not to use excessive force, as knobs can sometimes be tight. If it doesn't come off easily, try wiggling it gently from side to side or using a gentle tapping motion with a mallet or the handle of a screwdriver.

Once the control knob is removed, set it aside in a safe place to avoid misplacing or damaging it. With the knob removed, you should now have access to the inner workings of the switch, allowing you to proceed with further repairs or replacements.

Replace the switch: Take a photo of the wires, then transfer them to the new switch

Before beginning any work on your Aroma hot plate, ensure that it is unplugged from the mains. This is important for your safety.

Now, to replace the switch, the first step is to take a photo of the wires. This will be useful when you need to reattach them to the new switch. It is important to keep the wires in the right order, so changing them over one at a time is a good idea. Use a small flat-headed screwdriver to prise the electrical connections if required, but take care not to damage the wires.

Once all the wires are connected to the new switch, you can reattach the switch to the control panel and screw the control panel back into place. Put the control knob onto the selector switch shaft, and you're almost done! Just remember to take care not to trap any of the electrical wiring when putting the control panel back on.

Finally, turn the supply back on and test your repair. If you have followed these steps correctly, your Aroma hot plate switch should now be working properly.

Reassemble: Reattach the switch, control panel, and heat shield

Now that you have replaced the switch, it's time to reassemble your hot plate. Start by reattaching the switch to the control panel. Make sure to line up the switch with the control panel correctly and secure it in place with screws.

Next, you can reattach the control panel back to the appliance. Ensure that all the electrical wiring is properly connected and not trapped when putting the control panel back on. Secure the control panel with the appropriate screws.

Once the control panel is in place, you can now refit the heat shield. This will involve screwing the heat shield back into place, ensuring it is secure and properly aligned.

Finally, put the control knob back onto the selector switch shaft. Ensure that it is securely attached and properly seated.

After completing these steps, your Aroma hot plate switch should be successfully repaired and reassembled. You can now test the hot plate to ensure it is functioning correctly. Remember to follow safety guidelines and always disconnect the appliance from the power source before performing any repairs or testing.
