Microwave Carousel

I never noticed that before. I guess I'll have to look through the door to see. I would imagine it's for getting more of the food hot or more even cooking.
 
Easy to understand. The motor applies force or rotation against the least amount pressure. When it 1st. starts direction is pretty neutral as far as weight resistance detection goes. Once stopped reversal typically happens since the weight of whatever is being microwaved can shift a little.

The path of least resistance in action. That helps with what Ruthanne posted.

That's what you said. :oops:

What I would have said: "Just because." :ROFLMAO:
 
It’s a cheap-ass motor and just can’t decide which way to go. I think the manufacturers don’t say anything about it & leave it to us to ponder its purpose. Some people probably think its a sophisticated function that’s critical to it’s operation. I’m surprised there’s not some conspiracy theory about it already. In reality it’s just a cost saving thing to save a few pennies. Most motors are designed to always run in a predetermined direction but it’s a little cheaper to leave those components out if not necessary. Which direction it starts turning is a matter of timing between the motor stator position & the applied AC voltage. It’s really a quasi random thing although load may have play roll too.

Why does the microwave rotate sometimes clockwise and other times anticlockwise seemingly randomly?
The motor driving the turntable is an ac inductive type.

With this kind of motor there need to be capacitors of the correct value for both the incoming voltage frequency and the power rating of the motor, if said capacitors are off value the motor can run in reverse (this also happens when the capacitors begin to fail).

I've tried to explain this in layman's terms as the technical reasoning for it is quite complex and involves vector diagrams."

The motor has a two-way flux capacitor, one way sends your food a tiny way into the future, then the motor reverses and brings it back.
