Microwave Repair

Ode to microwave

When I first came across you,
On that bright Sunday morn,
Your glass door glistened,
Yet your case looked forlorn.

On enquiring on your state,
I was rightfully told,
“The plate does spin around,
Yet the contents remain cold.”

Bundled in the back of the car,
To the workshop, we made haste!
With the hope in our heart,
That you won’t be electrical waste.

Your issue was easily solved,
No need for mathematics,
The problem was so obvious,
When looking at your schematics.

After removing your case,
To reveal the fuse at fault,
Rated for less than one amp,
But also to five thousand volt!

A spare was ordered online,
From the wonder of eBay,
Stating a delivery time,
Of one-to-two working days.

Once put back together,
A quick test was done,
To find that your real power is,
Eight hundred and eighty one!

Now with you all fixed up,
It’s time you must go on,
Continuing to warm food,
With your cavity magnetron.
