F32
KitchenAid Dryer
Severity:What Does This Error Mean?
F32 means the moisture sensor bars inside the drum are reading a short — conductivity that is too high even on a fully dry load. Dryer sheet residue coating the sensor bars is the most common cause and can be cleaned without any parts replacement. A genuinely failed moisture sensor requires replacement.
Affected Models
- KitchenAid Front-Control Dryer
- KitchenAid KHED Series
- KitchenAid YKEDB Series
- KitchenAid Artisan Series Dryer
Common Causes
- Dryer sheet residue or fabric softener coating has built up on the sensor bars, bridging them with a conductive film
- Moisture sensor bars are shorted internally — the sensor has failed
- Two sensor bar wiring leads are touching or shorted near the sensor
- A metallic item in the load is bridging the sensor bars during the cycle
- Moisture condensed inside the drum near the sensor bars
How to Fix It
-
Locate the moisture sensor bars — two parallel metal strips mounted on the front interior wall of the drum, just inside the door opening.
On KitchenAid dryers, the sensor bars are usually positioned near the lint screen opening, at the bottom-front of the drum interior.
-
Clean the sensor bars with a cloth moistened with white vinegar or rubbing alcohol. Rub firmly along the full length of each bar.
Dryer sheet coating is waxy and often invisible. Even a lightly coated bar can register as a short. Vinegar dissolves the waxy residue effectively.
-
Dry the bars completely before running a cycle.
Wet sensor bars will register moisture and affect drying performance. Allow a few minutes to air dry after cleaning.
-
Run a small load through a complete cycle and check whether F32 returns.
If the cycle completes without F32, the sensor coating was the cause.
-
If F32 returns after cleaning, have a technician test and replace the moisture sensor.
The sensor assembly is a replaceable part, usually accessible from inside the drum without major disassembly.
When to Call a Professional
If cleaning the sensor bars does not resolve F32, the moisture sensor assembly needs to be tested and likely replaced.
Frequently Asked Questions
Are dryer sheets causing my F32 error?
Dryer sheet residue is one of the most common causes of F32 and also of poor auto-dry performance. Switching to dryer balls instead of sheets and cleaning the sensor bars monthly will prevent this fault from recurring.
How much does a moisture sensor replacement cost?
A replacement moisture sensor assembly for a KitchenAid dryer typically costs $20 to $60 for the part. With technician labor, the total repair usually runs $80 to $160.
Will F32 prevent the dryer from running at all?
On most KitchenAid models, F32 stops the auto-dry cycle but timed-dry cycles may still function. Consult your owner's manual — behavior varies by model generation.
