Maytag Dryer Error Code F24 — What It Means & How to Fix It

What Does This Error Mean?

F24 means your Maytag dryer's inlet thermistor is reporting a temperature above the maximum value the control board accepts. The inlet thermistor monitors the temperature of air as it enters the drum — if it reads too high, the control board stops heating to prevent overheating. A blocked vent, excessive drum temperatures, or a failed thermistor are the typical causes.

Affected Models

Maytag MEDB835DW
Maytag MEDC215EW
Maytag MED5500FW
Maytag Bravos Dryer

Common Causes

Inlet thermistor has failed and is reporting an out-of-range high reading
Exhaust vent is blocked, causing heat to back up into the inlet air path
Lint filter is heavily clogged, restricting airflow and raising drum temperatures
Wiring to the inlet thermistor is damaged, causing a false high reading
Control board fault misinterpreting the thermistor signal

How to Fix It

Clean the lint filter and inspect the exhaust vent for blockages before anything else.

A clogged lint filter or blocked vent is the most common cause of F24. Clear these first before investigating the thermistor.
Check the exterior vent cap for lint buildup or blockage.

Go outside while the dryer is running and confirm the vent flap opens freely.
Unplug the dryer for 5 minutes and then restart a short timed-dry cycle.

Clearing the vent and resetting the control board often resolves F24 when the cause was a temporary temperature spike.
If F24 returns after cleaning the vents, have a technician test the inlet thermistor resistance.

The thermistor should read within a predictable resistance range at room temperature. A reading outside that range confirms the sensor has failed.

When to Call a Professional

If cleaning the lint filter and vents does not resolve F24, the thermistor likely needs testing. A technician can measure the thermistor resistance to confirm whether it is reading within range or needs to be replaced.

Frequently Asked Questions

What is the inlet thermistor and where is it located?

The inlet thermistor is a small temperature sensor that measures the air temperature as it is drawn into the drum. On most Maytag dryers it is mounted near the drum inlet opening. Accessing it requires removing the dryer's top or front panel.

Is F24 the same as F22?

They are related but distinct. F22 indicates the exhaust thermistor is reading out of range — it monitors air leaving the drum. F24 indicates the inlet thermistor is reading too high — it monitors air entering the drum. Both often have the same root cause: restricted airflow.

How much does an inlet thermistor replacement cost?

An inlet thermistor for a Maytag dryer typically costs $15 to $40 for the part. With technician labor, the total repair usually runs $80 to $150.
