Genuine OEM dryer timer for Speed Queen and Huebsch commercial and residential dryers. This critical component is the electromechanical timer that controls all dryer cycle operations including cycle selection, heat timing, cool-down period, and automatic shut-off. The timer is a 3-cycle model designed for retail/residential dryers operating on 240V 60Hz power. The timer includes a rotary dial mechanism, internal motor, cam-operated switches, electrical contacts, and connector terminals. Unlike electronic control boards, electromechanical timers use a small synchronous motor to rotate a series of cams that open and close electrical contacts at precise intervals, controlling the dryer's heating element, motor, and other components throughout the drying cycle. When this component fails, you'll experience the dryer not starting, timer not advancing through cycles, dryer running continuously without shutting off, heating element not turning on, dryer stopping mid-cycle, timer dial not turning, or incorrect cycle timing. Dryer timers fail due to electrical contact wear, motor failure, mechanical binding, moisture exposure, power surges, or age-related component degradation. The timer is located on the control panel at the top front of the dryer, behind the timer knob. This is a 240V 60Hz model specifically designed for North American retail/residential dryers with 3 cycle options (typically Normal, Permanent Press, and Delicate/Air Fluff).
