Star popcorn machine model 39sa - Nostalgia Electrics KPM-508 Popcorn Maker

The motor output shaft bushing might have came loose I have seen where it falls out of the motor and the shaft becomes real wobbly and it will cause excessive wear in the kettle cross bar bushing too. also make sure the cross bar and lid assy. is not come loose from the kettle.

Star 59 is an 8oz popper, they stopped making them in 1992. Parts are becoming very expensive, usually better to dispose of the machine.
I have some used parts available, depending on which ones you want, or you could try partstown.com for Star parts.

That model has a thermostat (also called a high limit) that is set at 450F. it should produce a popping cycle of 3 mins, and yes will burn popcorn if you don't dump it fairly quickly.
The speed it heats cannot be too fast, there is only so many watts in the heat element. it may go to hot, but never to fast.
The best way to test temp is time the 2nd popping cycle with a stop watch. the second batch should be 3 mins +/- 30 seconds. if it is 4 mins it is too cold. a 2 min popping cycle is to hot.
A popper that is too cold is also popping poor quality popcorn, higher amount of unpopped kernels, and small chewy popcorn.
Measure carfully when doing time test popping. That model is 2oz oil, 6oz popcorn, and 1 tsp salt. Start timing when you put ingredients in, and stop when you dump it. The kettle must be hot, that is why you time the 2nd batch.

That is a common problem in the Star Model 89. Replacement motors are available from restaurant parts supply houses.


They stopped making that model in 1992, so the part will be fairly expensive, in the $200-$300 range.

Hi,
I was able to find out that the Start 39 popcorn makers are 6 oz capacity. The star 86 models are 8 oz capacity. I could not find a model labeled "Star 59"
Here is a link below to the manufacturer's website that should help you.

It depends on the serial number. You can go to the factory website and found it there under the manuals search
