What we can confirm
Signal PF, from the manufacturer's own documentation
This code has no number, because this equipment has no display to put one on. The appliance signals it instead — an alarm, a symbol or a pattern of lights — and what it means is recorded in the documentation that ships with it.

What else belongs to the dryers
On this make a code belongs to the appliance rather than to a product line. These are the other conditions this machine can display, and the models that can show this one — a display often has more than one thing to say, and the model number decides what any of it costs to put right.

About Whirlpool-built Kenmore dryer signal PF
Whose code this actually is
Kenmore did not write PF, because Kenmore has never built an appliance. This one is Whirlpool's, and it appears on the dryer that Whirlpool built and Sears sold under the Kenmore badge. Whirlpool, LG and Frigidaire all built dryers for this badge, and all three publish short two-character codes, so a lookup that skips the prefix is a coin toss dressed as an answer.
What the appliance is telling you
A power failure interrupted the drying cycle.
This one is an indicator rather than an error. It is published in the same table as genuine problems, and treating it as one is how a working appliance gets a service call.
Which Kenmore models can raise it
The Kenmore dryer whose model number begins 110 — the three digits before the period on the rating plate. Those digits are Whirlpool's, which is why Whirlpool's table is the one that applies to PF and no other manufacturer's does.
Nothing is broken here
This clears on its own or after the appliance is restarted, and no part is involved. If it keeps coming back without anything obvious causing it, that repetition is the finding rather than the message itself.

Where this usually goes
The job this most often becomes is diagnostic visit, and that page carries a starting figure and the reasons that move it. A Kenmore dryer in South Florida is almost always on a long horizontal duct carrying humid air, and that duct is behind more heat and airflow codes here than any component inside the machine. Photograph the display before you cut the power: a reset clears PF, and on a Kenmore the characters plus three digits off the plate are most of the diagnosis.
Where this meaning came from
Whirlpool's own documentation: Dryer error codes — Whirlpool Product Help. Kenmore publishes none of its own, which is why every entry on this site names the manufacturer's document instead.
