Type of Service

Power Relays (White/Black Blocks): These electro-mechanical switches regulate high-current paths for the dryer heating element and motor. Pitted, stuck, or burned internal contacts frequently cause a dryer to never heat or fail to spin.Step-Down Transformer (Yellow Component): This converts the main household power down to low-voltage DC to power the onboard microchips. If it fails or develops open windings, the entire dryer will appear completely dead.Electrolytic Filter Capacitors (Blue Cylinders): Check the tops of these cylinders for any bulging, dome-like shapes or leaked fluid. Degraded capacitors cause erratic power delivery, causing the appliance to turn off mid-cycle or reset randomly.Crucial Repair Steps & Safety
