Maintaining Your Microwave for A Longer Lifespan 

 September 5, 2025

The appliances in our home will have a longer lifespan if they are being maintained properly and on a regular basis. For this instance, the microwave can greatly benefit from good maintenance because it can address the most minor concerns. 

If you want to give your microwave some basic attention, then here are some tips on how you should do it!

Maintaining Your Microwave for A Longer Lifespan

Think about your dishes

You always need to be cautious about the materials you are microwaving your food on. This means using only microwave-safe dishes. Nothing you put in your microwave should contain any metal. Otherwise, look for microwave-safe labels on your dishware to be certain they won’t harm your microwave. In general, if the container you are using to microwave food gets hotter than the food itself, you should refrain from using that container to microwave your food in the future. 

Mind the door

While many don’t give a second thought to slamming their microwave door, this can eventually damage the unit as a whole since microwave latches are typically quite complex. In addition, pulling the door open while the microwave is on can blow the safety fuse. Source: Wilshire Refrigeration & Appliance

Clean stubborn stains using baking soda

Create a paste with baking soda and water. Apply this to any stubborn spots inside your microwave. Leave it for a few minutes, then scrub off gently. Rinse thoroughly to avoid leaving any residue.

Using baking soda helps you avoid harsh cleaners that can damage the interior of your microwave. To avoid stubborn spots and stains inside your microwave, clean splattered food residue after each use and cover food with a microwave splatter cover to help keep the microwave cavity clean.

Clean the grease filters and outside vent damper

For an over-the-range microwave, cleaning the grease filters is essential to kitchen safety and smooth microwave operation.

Follow the steps shown in the owner’s manual to remove the grease filters. Soak the filters in hot, soapy water in the kitchen sink for 15 minutes to help remove grease. Rinse the filters off with hot water and dry them fully before reinstalling them in the microwave.

Carefully check the vent damper on the outside of your home. Wasps love to take up residence in this area. Check the damper for blockage by a wasp nest or other obstructions and clean out the vent cover. Make sure the vent damper opens and closes smoothly. Lubricate the vent damper hinges with silicone spray if necessary.

Listen for unusual sounds

If your microwave is making strange noises, it could be a sign of a malfunction. Buzzing or grinding noises might indicate an issue with the turntable or the motor. Addressing these signs early can help avoid bigger problems.

Watch out for odors
