Microwave Turns on But Doesn't Heat Food


My Delonghi microwave lights up, and the turntable works, but it doesn't heat. Any ideas? Cheers.

This happened to us. You're element has gone out & you'll need to buy a new microwave (or one at the thrift store). In the USA you can get one for only $25. I paid $50 & got a really nice one. I was surprised at how cheep they are!

* This doesn't apply to burned-out elements, but for other microwave problems. I have a friend that used to repair microwaves back in the 70's when they were costly & he told me that what kills most microwaves is people slamming the microwave's door. Tell your family to always shut the microwave's door quietly & gently & your microwave will last many years longer!

Guess that's it then. Off to the shop. Thanks Cyinda, also for the tip about shutting the door gently. All the best Marg.

Before you replace it. or buy a new element, try unplugging it for about 5 minutes. Then plug it back in. Sometimes it just needs a reset.

It is probably a fuse. You can go in the search bar and look under troubleshooting a microwave that doesn't heat and it will help you with step by step instructions. Good Luck.

The over-the-range microwave oven will power on, but will not cook/heat. Is it the microwave or the outlet?

RE: Microwave Turns On But Doesn't Heat Food

Ours stopped working just like yours at 11PM the night before Thanksgiving. The next morning at 8 am my husband was in KMart getting a new one as trying to serve Thanksgiving dinner. Without one with our menu plan would have been difficult.

We think the problem is with the magnetron. Without it functioning, it is like turning on a gas oven without access to gas. The mechanism to provide the heat is not working. Look up your model on the internet and see what you can come up with. Our particular brand had a ton of people who posted the exact same difficulty with it. It was the magnetron.

It was a shame, because I only had this microwave for 1.5 years and it broke. It was not worth fixing. It was just as costly to replace it as to repair it. The microwave I had before this one lasted 23 years. The only reason I bought this new one was, because the old one's handle broke and I could not open or close the door. The thing still worked, though. (12/24/2008)

The motor and the fan is working, but the heating element is broken. The easiest fix is a new microwave. Sorry. This also happened to us. These days you can buy a top-of-the-line one for under 50 bucks, or a cheapie one for only $30. We paid $60 not on sale) it was the very best you could buy. There's always the Goodwill or thrift stores. A used one can be had for less than $20. Make sure you bring in a bottle or a cup of water so you can plug it in and test it first. A used one could last you for one day or 20 years. Ya just never know. (12/27/2008)
