General Electric Dryer DBB3300GA2AA Timer will not advance

This timer controls the drying cycle by advancing through settings and routing power to the motor and heater. Replace a worn timer if the cycle won't advance, runs indefinitely, or stops unexpectedly on certain selections.

• Advances the dryer through timed/auto cycles and sets overall cycle length
• Directs power to motor and heater according to the selected program
• Coordinates cycle start/stop and end-of-cycle shutoff
• Failure symptoms include: timer not advancing, dryer runs but won't shut off, stops mid-cycle, or won't start on certain settings

• Disconnect power before servicing
• Access the timer from the control panel; retain and reuse original mounting screws
• Move wires to the new timer one at a time; label or photograph connections for reference
• Reassemble and test all cycle selections for proper advance and shutoff
