Amana Dryer Error Code F:22

The F:22 code means the outlet thermistor circuit is open, indicating the control board is receiving no signal from the temperature sensor located at the dryer exhaust outlet. This sensor monitors the air temperature leaving the drum, and an open circuit means continuity has been lost in the sensor or its wiring. The dryer will not run while this fault is active. Diagnostic testing of the thermistor and its circuit is required to resolve the issue.

No, you should not continue using the dryer while the F:22 code is active. The outlet thermistor is a safety-critical component that helps prevent overheating. Without a functioning temperature sensor at the exhaust, the dryer cannot properly regulate heat, which creates a potential fire or overheating hazard. The dryer will typically disable itself when this fault is detected.

If the outlet thermistor itself is the failed component, the part typically costs between $15 and $40, making it a relatively affordable repair. If a technician is needed for diagnosis and replacement, total repair costs including labor generally range from $100 to $200 depending on your area. If the control board is ultimately at fault, costs can be higher, typically in the $200 to $350 range for parts and labor combined.

A knowledgeable DIYer can often resolve this code by testing the outlet thermistor for continuity and resistance, then replacing it if it reads open. You will need a multimeter and basic disassembly tools. If the thermistor tests fine, inspecting and repairing the wiring harness is the next step. If you are not comfortable working with wiring or internal dryer components, a qualified technician is recommended.

A power reset may temporarily clear the code display, but the fault will return as soon as the control board checks the thermistor circuit again during operation. The underlying problem, an open thermistor or broken wiring, must be physically repaired or replaced before the code will clear permanently. Resetting without fixing the root cause is not a solution.
