What is the F22 error & why would it display on my dryer?

The F22 error code appearing on the user interface of a Maytag dryer usually points to a problem with the outlet thermistor, which monitors the dryer’s exhaust temperature. This error code can occur in both electric and Maytag gas dryer models.

The F22 error can be triggered by several issues within the dryer, including the following:

• A faulty outlet thermistor
• Blocked airflow
• Faulty wiring
• Power interruption or failure

Safety tips

When working on any appliance, always keep safety first to avoid personal injury or damage to the appliance or its parts. Here are some tips to keep in mind:

• Always power off and unplug your appliance or switch off the circuit breaker before you attempt any maintenance or replacement work. This keeps you safe by eliminating any risk of electric shock.
• If the appliance has recently been used, give it plenty of time to cool down before working on it.
• If you have a gas model, shut off the gas supply to prevent leaks while you work.
• Take your time while working to prevent accidents and personal injuries. Rushing is the enemy of precision.
• Work in a well-lit area so you can see and access appliance parts.
• Keep your workspace free of clutter and other obstacles. Keep children and pets away from the work area.
• Never work on internal parts with wet hands. Make sure the work area is completely dry.
• Check the user manual to see if there are specific installation or safety instructions related to your appliance or replacement part.
• Be gentle when handling or removing parts. Excessive force might damage the appliance or cause personal injury.
• Wear insulated work gloves to protect your hands from sharp metal parts and debris.
• When working with wires, avoid touching any exposed wires or terminals. If you need to touch a wire, use a non-conductive tool or wear insulating gloves to prevent electrical shock.
• Always take photos or make a note of wiring terminals or other connections before disconnecting them to make reassembly easier.
• Don’t test live voltage with a multimeter if you’re unfamiliar with how to prevent short-circuiting.

How to troubleshoot the F22 error code

To resolve the F22 error on your Maytag dryer, follow these steps.

Step 1: Reset the dryer

Also known as power cycling, resetting the dryer can help you determine if the F22 is just a glitch or a sign of something more serious happening inside the machine.

1. Unplug the dryer from the power outlet.
2. Leave the dryer unplugged for around 2-3 minutes.
3. Plug the dryer back in and see if the F22 error disappears.

If you’re still seeing the F22 fault code, move on to the next step.

Step 2: Check the lint filter and exhaust vent

An accumulation of lint can block airflow, which can increase the temperature and trigger the F22 error code.

• Check the lint filter (also called a lint trap) and clean it. This trap should be cleaned after each drying cycle.
• Make sure the vent hose is well connected and not kinked or bent.
• Check the exhaust vent for any damage and replace it if needed. Clean the exhaust vent with a brush or use a vacuum cleaner to remove all debris.
• Use a long-handled brush to clean the entire length of the vent.

Once you’ve made sure the vent and lint filter are clean, plug the dryer back in and see if the error persists. If it does, continue troubleshooting.

Step 3: Inspect and test the outlet thermistor

1. Make sure the dryer is unplugged from the power outlet.
2. Find the outlet thermistor, which is usually found near the blower wheel housing or exhaust duct.
3. Look over the thermistor for any visible signs of damage or wear such as cracks, frayed wires or discoloration. If you notice any issues, replace the thermistor.
4. Set a multimeter to resistance mode (Ω) and use the probes to test the thermistor. You’ll need to refer to the manufacturer’s specifications in the user manual or technical sheet, but the thermistor should typically read around 10k Ohms at room temperature.

If the outlet thermistor tests OK, move on to the next step.

Step 4: Check the wiring

Examine all the wiring connections, including those of the control panel and main electronic control board. Look for any loose or broken wires as these can disrupt the flow of electricity and trigger the F22 error code.

If you find any damaged wires, replace them. If you find any loose connections, reseat them so they’re secure.

Once you’ve replaced the wiring or fixed loose connections, plug the dryer back in to see if the error code has disappeared. If it hasn’t, replace the control board as a last resort.
