The 33953375 is a genuine OEM dryer timer for Maytag and affiliated brand electric dryers. This mechanical timer is a critical component that controls the duration and sequence of drying cycles, managing key stages including drying time, cool-down periods, and end-of-cycle functions. The timer is a motor-driven mechanical device consisting of an electric motor, a gear and cam system, electrical contacts, and a housing assembly. The timer motor operates on 120 volts AC, 60 Hz and rotates a series of internal gears and cams that physically open and close electrical contacts in a precise sequence throughout the drying cycle. The timer measures approximately 3-4 inches in width and 2-3 inches in height, weighing approximately 0.3-0.5 pounds. The timer has multiple terminal connections (typically 6-8 terminals) that connect to the dryer's electrical circuit, including power input, heating element control, motor control, and end-of-cycle functions. The 33953375 replaces older part numbers including WP33953375, 33953375, and others with improved reliability and durability. The timer motor contains precision gears and cams manufactured to exact specifications to ensure accurate cycle timing and proper sequencing of dryer functions. The internal cam system is designed to activate specific electrical contacts at predetermined times during the drying cycle. When the dryer is turned on and a drying time is selected, the timer motor begins rotating at a constant speed. As the motor rotates, the internal cams gradually rotate, opening and closing electrical contacts in sequence. These contacts control the heating element, blower motor, and other dryer functions. When the selected drying time has elapsed, the final cam contact opens, shutting off the heating element and initiating the cool-down cycle. Over time, dryer timers can fail due to motor failure (motor windings burning out or motor bearings wearing out), gear or cam wear or breakage, electrical contact wear or burning (from arcing), solder joint failure on the circuit board, component corrosion from moisture exposure, or manufacturing defects. When the timer fails, symptoms include the dryer not starting at all, the dryer starting but not heating, the dryer running but not shutting off at the end of the cycle (running indefinitely), the dryer shutting off prematurely before the cycle completes, the timer knob not turning or being stuck, unusual clicking or grinding sounds from the timer area, the dryer making buzzing sounds but not running, or the dryer cycling through drying and cool-down repeatedly without stopping. The 33953375 is a complete replacement timer assembly that restores full dryer operation and precise cycle timing. Replacing a faulty timer eliminates all timer-related problems and restores reliable, accurate drying cycles. Important: Always turn off power at the circuit breaker before working on the dryer. This is a moderately advanced repair requiring careful handling of mechanical components and precise reconnection of multiple terminal connections. Verify your dryer model number before ordering. Test the timer with a multimeter before replacement to confirm timer failure. This repair can be completed by most homeowners with basic mechanical skills and careful attention to detail.
