General Electric Dryer DBB3300EA0WW Doesn't shut off

The Timer Knob Assembly is an OEM part for GE dryers that is responsible for controlling the dryer's timer, allowing users to select the desired cycle duration and start the dryer. Over time, the timer knob can become worn or damaged due to frequent use or accidental impact, leading to difficulties in setting the dryer timer or starting the machine. If you need the bisque colored version of this knob, you can order it here: WE1M483.

Common causes of a bad timer knob include cracking or breaking due to frequent use, the internal mechanism wearing out, or the knob becoming loose and no longer fitting securely on the timer shaft.

This part fixes the following symptoms-

• The knob slipping or failing to grip the timer shaft 
• Cracks or breaks in the knob 
• The knob coming off the timer shaft completely 

This OEM GE part can also be used on Hotpoint, RCA, and Kenmore/Sears appliances. 

The Door Switch is an OEM part for GE dryers, designed to ensure the dryer does not operate when the door is open. This safety feature is crucial for preventing accidents and ensuring the appliance operates efficiently and safely. The switch signals the dryer's control system about the status of the door—if it's open or closed—thereby allowing or preventing the start of a drying cycle. 

Causes of damage to the door switch often include mechanical wear from repeated use, accidental damage from loading or unloading, or electrical issues such as short circuits. 

Symptoms of a bad Door Switch include:

• The dryer not starting when the door is closed 
• The dryer continuing to run when the door is opened
• Unusual noises or the dryer stopping mid-cycle

This OEM GE part is also compatible with Hotpoint, RCA, and some Kenmore models.

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
