Electrical System

Electrical schematics and component testing procedures.

Main Components: Control board, motor, heater, thermal fuse, moisture sensor, door switch, start switch.

Wiring: Follow color-coded wiring diagram. Voltage testing: Use multimeter to verify 240V at terminal block, 120V at motor, proper continuity through safety switches. Resistance values: Heater element (10-20 ohms), motor windings (2-10 ohms), thermal fuse (0 ohms continuity).

Testing and Diagnostics

Step-by-step diagnostic procedures for common issues.

Power supply check: Verify 240V at terminal block.
Control board test: Check for proper voltage output to components.
Motor test: Verify rotation and proper winding resistance.
Heater test: Check element resistance and thermal fuse continuity.
Sensor testing: Verify moisture sensor operation and calibration.
Safety switch test: Check door switch and thermal cutoffs.

Tip: Use diagnostic mode by pressing specific button sequences for error code display.

Troubleshooting Guide

Common problems and solutions for the LG DLE2301R dryer.

Symptom	Possible Cause	Corrective Action
No power	Power supply/thermal fuse	Check power cord connection; test thermal fuse; verify door switch.
No heat	Heater element/thermal fuse	Test heater element resistance; check thermal fuse continuity; verify cycling thermostat.
Drum not turning	Belt/motor/drive system	Inspect drive belt; test motor operation; check idler pulley.
Overheating	Ventilation/thermostat	Clean lint filter and exhaust duct; test high limit thermostat.
Error codes displayed	Sensor/control board	Refer to error code chart; test sensors; check control board connections.

Reset: Unplug for 5 minutes to reset control board if needed.
