Have an F22 error code flashing on your Maytag dryer display? Don’t panic. This common issue is actually quite easy to diagnose and fix yourself. The F22 code simply means there is a problem with the dryer’s exhaust thermistor, which monitors air temperatures. By following some simple troubleshooting steps, you can have your dryer back in working order in no time. Let’s explore what causes the F22 error and how to troubleshoot it like a pro with a few basic checks and inexpensive part replacements.
Understanding F22 Error Code
Seeing an F22 error code pop up on your Maytag dryer display can be confusing. But don’t worry! This error is easy to understand and fix once you know what causes it.
What is an F22 Error Code?
The F22 error code tells you there is a problem with your dryer’s outlet thermistor. A thermistor is a small device that measures temperature. The outlet thermistor checks the temperature of the air leaving your dryer. It makes sure the air isn’t too hot before it enters the vent.
Why Does the F22 Error Appear?
There are a few reasons why the F22 code may show up:
- The outlet thermistor is broken
- There is blocked airflow in the dryer
- There is a wiring problem
- The power was interrupted
The most common cause is a faulty outlet thermistor. This inexpensive part wears out over time. When the thermistor can’t accurately read the air temperature, the F22 code appears.
Other issues like blocked vents or loose wiring can also trigger the error code. The dryer’s computer detects that the thermistor readings are off and throws the F22 code.
Safety Tips for Repairing a Maytag Dryer
Working on any appliance can be dangerous if proper precautions aren’t taken. Follow these essential safety tips to avoid injuries or accidents when troubleshooting and repairing your Maytag dryer.
1. Power Off and Unplug the Dryer
This is the most critical step! Make sure to unplug the dryer from the electrical outlet before doing any work. This prevents electric shocks or electrocution.
2. Let the Dryer Cool Down
Allow time for the dryer to cool completely before servicing it. The interior and parts become very hot during operation. Wait a few hours after a cycle to let temperatures normalize.
3. Shut Off the Gas Supply
For gas dryer models, make sure to turn off the gas shut-off valve. This will cut off the gas supply and make it safe to work on the appliance.
4. Work in a Clear, Well-Lit Area
Remove clutter and make sure the area around the dryer is bright. This allows you to see what you are doing and prevent accidental injuries.
5. Keep Your Hands Dry
Never work on an appliance with wet hands. Also, avoid touching any exposed wires or terminals when testing with a multimeter.
6. Take Photos Before Disconnecting Wires
To easily reconnect wires, take photos or make diagrams before disconnecting any wiring harnesses or terminals.
7. Don’t Test Live Voltages if Unfamiliar
Avoid testing live voltages with a multimeter if you are not familiar with proper probing procedures. You can accidentally short connections.
Troubleshooting a Maytag Dryer F22 Error
Got the F22 error on your Maytag dryer? Don’t sweat it. Just follow these easy troubleshooting steps to diagnose the problem and get your dryer running again.
Step 1: Reset the Dryer
Before diving into repairs, try resetting your dryer first:
- Unplug the dryer from the outlet for 2-3 minutes
- Plug it back in and check if the error code went away
Resetting the dryer will clear any temporary glitches that caused the F22 error.
Step 2: Check the Lint Filter and Vent
If resetting didn’t work, your next step is to clean and inspect the dryer venting:
- Remove and clean the lint filter
- Make sure the vent hose is connected and not kinked
- Check the vent ductwork for damage or blockages
- Use a vacuum or brush to clean out the entire vent
Lint buildup and clogged vents are common causes of restricted airflow. This can activate the F22 code.
Step 3: Test the Thermistor
The main culprit for the F22 error is a faulty outlet thermistor. Here’s how to test it:
- Locate the thermistor near the blower housing or vent duct
- Check for visible damage. Replace if necessary.
- Use a multimeter on the “Resistance” setting to test it
If the thermistor readings are abnormal, replace this inexpensive part.
Step 4: Check the Wiring
Faulty wiring can also cause F22 errors:
- Inspect wiring to the control panel and circuit boards
- Replace damaged wires and reseat loose connections
- If needed, replace the circuit control board
