Understanding the Start Switch
The start switch in a GE dryer serves as the control mechanism that starts the drying process. It is typically located on the control panel and is activated when the user presses it. The switch completes the circuit, allowing electricity to flow to the motor and heating element. If the switch is faulty or the wiring is damaged, the dryer may not start at all.
Components of the Start Switch Circuit
To understand the wiring diagram, it's important to familiarize yourself with the components involved in the start switch circuit:
1. Start Switch: The push-button switch that initiates the drying cycle.
2. Motor: The component that drives the drum and operates the blower.
3. Thermal Fuse: A safety device that cuts off power if the dryer overheats.
4. Timer: Controls the duration of the drying cycle.
5. Power Supply: Provides the necessary voltage to the dryer components.
Wiring Diagram Overview
A wiring diagram provides a visual representation of the electrical connections within the dryer. Here is a simplified overview of the wiring diagram for the GE dryer start switch:
- Power Source: The power cord connects to the dryer’s internal wiring.
- Control Panel: Houses the start switch and timer.
- Wiring Connections:
- Power leads to the start switch.
- Wires from the start switch to the motor.
- Connections to the thermal fuse and timer.
Sample Wiring Diagram
While specific wiring diagrams may vary by model, a typical diagram for a GE dryer start switch might look like this:
- Power Supply:
- Black wire (L1) connects to the start switch.
- White wire (Neutral) connects directly to the motor.
- Start Switch:
- One terminal connects to the power supply (Black wire).
- The other terminal connects to the motor and the timer.
- Motor:
- The motor receives power from the start switch and returns to the neutral wire (White).
- Thermal Fuse:
- Positioned in series with the motor, ensuring that if it fails, the motor will not operate.
When examining the diagram, remember that color codes may differ based on the model and year of the dryer. Always refer to the specific manual for your model when working on repairs.
Steps to Access the Start Switch
Before you can examine the wiring or replace the start switch, you'll need to access it. Follow these steps:
1. Unplug the Dryer: Safety first! Disconnect the power supply to prevent electric shock.
2. Remove the Control Panel:
- Locate the screws that secure the control panel.
- Use a screwdriver to remove the screws and gently lift the panel.
3. Locate the Start Switch: The start switch is usually mounted on the back of the control panel.
4. Inspect the Wiring: Check for any loose connections, frayed wires, or signs of damage.
Troubleshooting the Start Switch
If your GE dryer won’t start, the start switch is one of the first components to check. Here’s how to troubleshoot:
Tools Needed
- Multimeter
- Screwdriver
- Wire cutter/stripper
- Electrical tape
Steps for Troubleshooting
1. Check for Power:
- Use a multimeter to test if power is reaching the start switch. Set it to AC voltage and probe the terminals.
- If there is no power, check the power cord and circuit breaker.
2. Test the Start Switch:
- Disconnect the wiring from the start switch.
- Set the multimeter to the continuity setting and connect the probes to the terminals of the start switch.
- Press the switch; if it does not show continuity when pressed, it’s likely faulty and needs replacement.
3. Inspect the Wires:
- Look for any signs of wear, fraying, or loose connections.
- Ensure that all connections are secure and clean.
4. Check the Thermal Fuse:
- If the fuse is blown, it can prevent the dryer from starting. Test it with a multimeter for continuity. If it’s faulty, replace it.
5. Examine the Timer:
- The timer can also affect the start switch operation. If the timer is malfunctioning, it may need to be replaced.
Replacing the Start Switch
If you’ve determined that the start switch is defective, replacing it is relatively straightforward. Here’s how to do it:
Necessary Tools and Materials
- Replacement start switch
- Screwdriver
- Multimeter
- Wire cutter/stripper
- Electrical tape
Steps to Replace the Start Switch
1. Purchase a Replacement: Ensure you buy a start switch that matches your dryer model.
2. Remove the Old Switch:
- Disconnect the wires from the old switch, noting their positions for reinstallation.
- Remove any screws or clips holding the switch in place.
3. Install the New Switch:
- Position the new switch in place and secure it with screws.
- Reconnect the wires according to the original configuration.
4. Reassemble the Control Panel:
- Carefully replace the control panel and secure it with screws.
5. Test the Dryer: Plug in the dryer and test the start switch to ensure it operates correctly.
