Printed circuit board with mounted electronic components

Wi-Fi and smart modules

Most "bad Wi-Fi module" calls are network problems: wrong band, weak signal or router settings. Prove the network first, then power-cycle, then check the module supply and connector before replacing the module or board.

How to test an NTC thermistor (temperature sensor) and read a resistance chart

NTC thermistors are used in refrigerators, dryers, washers, dishwashers, AC units and water heaters. Resistance falls as temperature rises. You test them by measuring resistance at a known temperature and comparing it with the chart for that exact sensor family.

How to test a water inlet valve (single, dual and triple coil)

Inlet valves are solenoid valves. Each coil opens one water path. Test each coil for resistance; a coil can be fine yet the valve still fail mechanically (clogged screen or stuck plunger), so check flow and the screen too.

How to test a PSC motor (common, start and run windings)

Permanent split capacitor (PSC) motors are used in AC condenser and blower fans, some washer and dishwasher motors. Test the capacitor first, then the three windings. The two individual readings must add up to the start-to-run reading, and nothing may read to ground.
