At [CompanyXYZ], we know that nobody wants their microwave sparking as they try to heat up their food. Below, our team of professionals outlines the troubleshooting steps to take if your Kenmore built-in microwave starts sparking.

Diagnose the Issue

When diagnosing the issue, the first step is to determine the source of the sparking. It could be due to:

  • Loose or frayed wiring in the door
  • Faulty switches or indicator lights
  • Loose component connections
  • Exposed wiring
  • Loose connections on the main power circuit
  • If a component has been replaced, it may not have been installed correctly

Unplug and Secure the Microwave

Unplug the microwave and securely cover any exposed wires before touching the inside of the microwave. Note that these troubleshooting steps should only be taken by an experienced technician. Attempting to diagnose and solve the issue yourself could lead to injury.

Remove the Outer Shell

Carefully remove the outer shell of your microwave. This will allow you to inspect the components and wiring more closely.

Check the Fuse

If the fuse appears burned or cracked, it will need to be replaced. Conversely, if the fuse appears intact and in working order, move on to the next step.

Check the Components

Check all other components such as the switches, indicator lights, and connections for any signs of wear or damage. If something appears loose or damaged, you may need to replace the entire component.

Attach the outer Shell

Once you have identified and resolved the issue, reattach the outer shell of the microwave and plug it in.


These steps should resolve your sparking microwave problem. To verify, turn on the microwave and run it with a load inside the unit. If the microwave runs without sparking, the issue has been resolved.

At [CompanyXYZ], we strive to provide the highest quality repair services available. If you are unable to identify and resolve the issue yourself, our knowledgeable and experienced technicians are always ready to help.

FAQ – Troubleshooting: Kenmore Built-in Microwave Sparking

Why does my Kenmore Built-in microwave spark?

The spark observed likely is caused by food remnants that have remained in the oven, causing arcing. The sparks occur when the microwaves generated by the magnetron come into contact with conductive materials like metal foil, or metals omitted by forgotten food. If sparking isn't remedied, the magnetron – the component responsible for generating microwaves – can be damaged.

How can I stop the sparking in my Kenmore built-in microwave?

Regular cleaning and maintenance is the key to avoiding a sparking microwave. Use dishwashing detergent to thoroughly clean the inside and outside of the device, removing all debris and food remnants. And keep an eye out for metal objects inside as these can cause sparks as well.

What are the signs that my Kenmore built-in microwave needs repairs?

A well-working microwave should operate without sparking. Additionally, the appliance should maintain its desired temperature and cook food evenly. Signs of malfunctioning may include discoloration, burning smells, bubbles in the food, and an inability to heat food.

If your Kenmore built-in microwave is sparking and/or showing any signs of malfunctioning, make sure to contact a reliable appliance repair provider right away.
