Component Test; Door Locking Motor - LG LDG3015SB Service Manual

Before testing any of components, perform the following checks:
NOTE:
1. The most common cause for control failure is corrosion on connectors.
Therefore, disconnecting and reconnecting wires will be necessary throughout test procedures
2. ALL units in the first few days of use should be checked for mis-wiring or loose connections
1. All/tests/checks should be made with a VOM or DVM having a sensitivity of 20,000 ohms per-volt DC, or
greater.
2. Check all connections before replacing components, looking for broken or loose wires, Failed terminals, or
wires not pressed into connectors far enough.
3. Resistance checks must be made with power cord unplugged from outlet, and with wiring harness or
connectors disconnected.
• Turn off the electrical supply and gas supply going to the range.
• Replace all panels and parts before operating
• Reconnect all grounding devices after servicing
- Failure to do so can result in death or electrical shock
NOTE: Below Ω value were tested at room temperature (77F/25°C)
