Belt up!

Feb 28, 2026 Last reply: 4 months ago 8 Replies

I just replaced the bulb in my Panasonic combi microwave/radiant oven, and discovered a rubber drive belt lying loose. It had evidently come adrift from its position connecting the main motor to the fan which wafts around the heat in conventional-oven mode. Here's a picture of the belt back in position: visible in the pic is a section of the belt which seems to be stretched (and possibly melted?).

A local microwave repair place checked with Panasonic about a replacement: they passed on the info with a mixture of apology and incredulity: £36.10!



I'm wondering if the existing belt is repairable by cutting out the damaged length and splicing the two new ends together. The repair guy warned me that the area does get pretty hot, so I'm not sure that a standard super- or other type glue would be up to the task, especially given the very small contact area.



Any thoughts would be welcome; thanks.


I'm not surprised - they have to warehouse all those spares for years, which has a cost. Look at what it costs for car parts...

I'd not bother trying to glue it - it's (presumably) stretchy which means it's going to be hard to get glue to stay put.

Can you measure the dimensions of the belt, and see if you can find a matching generic part? It looks like 'just' a rubber belt, I don't think it's a timing belt or anything specialised of that nature?

Although at some point it becomes more hassle than just paying the £36.10...

I agree.

I thought about that: I'm not sure where exactly to look but I'll have a search around.

Quite. But it's pretty galling when you consider that for very little more I could buy an entire counter-top radiant oven. OK it wouldn't exactly be top-of-the-line, but even so...

Thanks for your thoughts.

There are silicone rubber belts available, in case temperature is a real problem.

Is it a flat belt? they are made in thousands

measure the circumference and the width and google 'flat drive belt width Xmm by Ymm'

pick on a little smaller than what you have

Google Panasonic spares and see where that takes you. There might be someone selling them on eBay much cheaper than the repairer's source.

Hard to see but is it a “Vee” profile? Anyhow, I wouldn’t have thought that it would hurt to try a large suitably size o-ring.

Many thanks for all the thoughts and suggestions. I looked on eBay and discovered compatible belts with prices ranging from £8 to over £50; a £10 version is now on its way to me.
