F22
Maytag Dryer
Severity: CriticalWhat Does This Error Mean?
F22 means the exhaust thermistor is reading a temperature outside the safe range. The dryer shuts down automatically to prevent overheating. A blocked vent is the most common cause — and a serious fire hazard.
Affected Models
- Maytag MEDB835DW
- Maytag MEDC215EW
- Maytag MED5500FW
- Maytag Bravos Dryer
Common Causes
- Blocked or kinked exhaust vent hose trapping hot air inside
- Lint buildup in the vent duct reducing airflow significantly
- Exhaust thermistor has failed and is reading falsely high
- Dryer installed too close to the wall, pinching the vent hose
- Exterior vent flap blocked by debris, snow, or a bird nest
How to Fix It
-
Stop the dryer immediately and unplug it from the wall.
An overheating dryer is a fire risk. Let it cool completely before doing anything else.
-
Clean the lint filter.
This should be done before every single load. A full lint filter dramatically restricts airflow.
-
Pull the dryer away from the wall and inspect the vent hose.
Check for kinks, crushing, or disconnections. Replace accordion-style plastic vent hoses with rigid metal ducting.
-
Go outside and clear the exterior vent opening.
Remove any lint buildup, debris, or nesting material. The vent flap must open and close freely.
-
Once venting is fully clear, plug the dryer back in and run a short cycle.
Stay nearby for the first 10 minutes to make sure the dryer is heating normally and not overheating.
When to Call a Professional
Do not restart the dryer until the vent is fully cleared. If F22 returns after cleaning the vent, call a technician — the thermistor or heating circuit needs inspection.
Frequently Asked Questions
Is F22 a fire danger?
Yes — F22 indicates the dryer is overheating. A blocked vent is a leading cause of house fires. Do not restart the dryer until the vent is completely clear.
How often should I clean my dryer vent duct?
At least once per year, and more often if you dry many loads weekly. Professional vent cleaning services are inexpensive and worth it.
What type of vent hose is safest for a dryer?
Use rigid metal duct whenever possible. Flexible foil or plastic accordion hoses trap lint easily and should be avoided.
