Frequently Asked Questions
•What voltage readings should I expect on the control board's power supply?
You should typically find 5V DC and 12V DC test points. These may be labeled or found on a schematic. Use a multimeter to check these voltages with the washer plugged in and the power switch ON.
•How can I test the capacitors on the control board without desoldering them?
While not as definitive as removing and testing with a capacitor meter, you can use a multimeter set to capacitance mode (if equipped) to get a rough estimate. Be sure the power is disconnected and the capacitor is discharged before testing. Look for significant deviations from the capacitor's marked value.
•If the control board is damaged, is it better to repair or replace it?
The decision depends on the extent of the damage and your skill level. Minor damage, like a blown capacitor, can be repaired. However, if the MCU is damaged or there are multiple failed components, replacing the entire control board is usually more cost-effective and reliable.
