How do you reset the PF code on a Kenmore Elite dryer?
On Kenmore model 79680021900, the PF code means a power failure or power interruption was detected. To clear it, restore steady power, then press STOP/CANCEL (or PAUSE/CANCEL) twice to reset the display; then restart your cycle.
What PF usually means
PF is triggered when the dryer loses power during or between cycles. Common causes include:
- A brief outage or flicker
- A tripped breaker or blown fuse
- A loose plug at the outlet
- A power cord or terminal block connection that is not tight
- An overloaded circuit shared with other high-draw appliances
Quick reset and restart steps
- Make sure the dryer door is closed.
- Press POWER to turn the dryer on.
- Press STOP/CANCEL (or PAUSE/CANCEL) two times to clear PF.
- Select a cycle with the cycle selector knob.
- Press START/PAUSE to run the cycle.
For the exact button names and control layout on your unit, use the owner's manual.
If PF keeps coming back (what to check)
If PF returns repeatedly, focus on the power supply first:
- Confirm the plug is fully seated in the correct grounded outlet
- Reset the house breaker fully (OFF then ON) or replace the fuse (do not upsize)
- Avoid extension cords or power strips
- If the dryer runs but does not heat, check for a supply issue (some electric dryers can tumble with a partial power problem)
Power issue symptoms vs. likely cause
| What you notice | Most likely cause | What to do next |
|---|---|---|
| PF appears after a storm or outage | Utility interruption | Clear PF; rerun cycle |
| PF appears when starting a cycle | Weak/loose power connection | Check outlet, plug, cord connections |
| PF appears with other appliances running | Circuit overload | Move loads to another circuit |
| Dryer tumbles but heat is inconsistent | Electrical supply problem | Check breaker/fuses; verify proper supply |
Why it matters
A one-time PF is usually harmless, but repeated PF events can interrupt drying, cause longer cycle times, and point to a wiring or circuit problem that can lead to additional no-start or no-heat symptoms.

How to figure out dryer model number?
For Kenmore dryer model 79680021900, the model number is printed on the appliance identification plate, typically located inside the dryer door opening. Use that exact number when looking up parts, the wiring diagram, or cycle and error-code information in the 79680021900 owner's manual.
Where to look on the dryer
Check these common label locations (start with the first one):
- Inside the door opening on the cabinet frame (most common)
- On the back of the dryer near the top
- On a side panel near the front edge
- Behind a lower front access panel (more common on some gas models)
- Near the control console area (less common)
What to write down (and why)
Record both the model and serial number exactly as shown; they are used to match the correct parts list and documentation.
| Label item | What it’s used for | Example format |
|---|---|---|
| Model number | Correct parts and diagrams | 79680021900 |
| Serial number | Production run details | Letters and numbers |
| Power type | Correct electrical or gas setup | Electric or gas |
Tips to avoid ordering the wrong part
- Copy the model number character-for-character (no spaces added).
- If the label shows a series like 796.8002#9##, match your exact digits where the symbols appear.
- Use the model number when selecting common wear items like the dryer drum belt 4400EL2001F or the dryer heating element 5301EL1001J.
- If the label is worn, clean it gently with a damp cloth and good lighting; avoid scraping.
Why it matters
Kenmore model numbers identify the exact design family and component set. Even small model-number differences can change the correct drum belt, thermostat, thermistor, or heating element for your dryer.
You can also search by model number on this parts list or on Sears PartsDirect if you’re looking up additional Kenmore dryer parts.

What is the average life of a Kenmore dryer?
Most Kenmore dryers average 10 to 13 years of service life with normal household use. Your Kenmore 79680021900 can often run longer when airflow stays clear, the lint system is kept clean, and wear items (like the drum belt and rollers) are replaced before they cause bigger damage; see the owner's manual for care and maintenance details.
What affects dryer lifespan the most
A dryer usually fails early from heat stress, restricted venting, or worn moving parts. These are the biggest life drivers:
- Vent restriction (lint buildup in the exhaust duct) increases heat and run time
- Lint screen and housing buildup reduces airflow and can overheat components
- Worn drum support parts (rollers, idler pulley) strain the motor and belt
- Overloading stretches the belt and accelerates roller wear
- Skipped cleaning around the door opening and seals lets lint migrate into the cabinet
Maintenance that extends life (high impact)
The manual calls out routine cleaning and vent checks as key to dependable operation. We recommend:
- Clean the lint screen every load
- Check and clean the vent ductwork at least once per year
- Wipe the door opening and seal area to prevent lint and dust buildup
- Keep the dryer level so the drum rides correctly on the supports
- Address new noises quickly (thumping, squealing, scraping) before parts cascade-fail
Common wear parts to watch on model 79680021900
If your dryer still heats but gets noisy, stops tumbling, or takes longer to dry, these parts are frequent culprits:
| Symptom | Most likely wear area | Example part for this model |
|---|---|---|
| Drum will not turn, motor runs | Belt or idler system | Dryer drum belt 4400EL2001F |
| Thumping or rumbling | Drum support rollers | Dryer drum support roller 4581EL2002H |
| Squealing | Idler pulley | Dryer idler pulley 4560EL3001A |
You can order these and other replacement parts from the parts list for your model, or search by model number on Sears PartsDirect.
Why it matters
A dryer that runs with poor airflow or worn drum support parts typically runs hotter and longer per load. That extra heat and strain shortens the life of the heating system, motor, and thermostats, and it increases energy use.
