Maytag Dryer Error Code SAIL SWITCH CLOSED FAULT

This fault means the dryer's sail switch, an internal airflow sensor located near the blower, was detected in the closed position at startup when it should have been open. The controller waited 10 seconds for the switch to open on its own and then stopped operation to prevent running without confirmed proper airflow. The dryer will not start again until the underlying cause is identified and the fault is cleared.

No. The dryer is designed to prevent operation when this fault is active because the sail switch is part of the airflow monitoring system. Running a dryer with unreliable airflow detection creates a risk of overheating and potential fire. Do not bypass the fault or attempt to force the dryer to operate until the problem is properly diagnosed and repaired.

Start by locating the sail switch inside the blower housing area and visually inspecting it for damage, debris, or a jammed flapper. Use a multimeter set to continuity mode to test the switch contacts: with no airflow the switch should be open (no continuity), and the contacts should close when the flapper is manually actuated. If the switch shows continuity in the resting position without any airflow applied, the switch is defective and should be replaced.

You can attempt to clear the fault by unplugging the dryer for several minutes and then restoring power, but if the underlying problem is not corrected the fault will return immediately. The controller will detect the closed switch again within 10 seconds of startup and shut the dryer back down. A lasting fix requires inspecting and correcting the sail switch, wiring, blower, or ducting before the reset will hold.

Repair costs vary depending on the root cause. If only the sail switch needs replacement, parts typically range from around $15 to $50, and a technician visit would add labor costs bringing the total to roughly $100 to $200. If the control board is at fault, parts alone can range from $150 to $350 or more, with labor added on top. Simple fixes like clearing a blocked exhaust duct cost little to nothing beyond your time.
