Frigidaire Dryer F31C747CT0 Timer will not advance

This dryer timer is the cycle control that advances your dryer through Timed and Auto Dry settings. Replacing a failed timer restores proper cycle progression, start/stop, and end-of-cycle shutoff.

• Advances the cam and internal contacts to move the dryer through heat, motor, and cool-down steps
• Governs run time on Timed Dry and Auto Dry cycles
• Routes power to the correct circuits in sequence; a failed timer may not advance or may stop early
• Common symptoms include timer knob not moving, dryer running indefinitely, or not starting on certain settings

• Disconnect power; for gas models, also shut off gas
• Remove knob/dial, open the console, and unmount the timer
• Label or photograph wiring; transfer wires one at a time to the new timer
• Reassemble and test both a Timed Dry and an Auto Dry cycle
