Whirlpool Duet Model #WED9200SQ0 has no power to display - No lights - No Nothing. Had Power to Back Ground Block but Display will not light or Display is Blank - No Sound.
Pulled out my meter - had power going to Ground Block - Had Power going to Main Board - Had power going to Power Cube but no power out going to display. So I pulled both Board out and looked for burn on relay(s) or back of board - NON FOUND! Pulled out the Power Cube and decided to de-soldered the large Black Capacitor with the values of 250V 100mfd - pulled my digital meter out after desoldering the Capacitor off the board and found ZERO mfd on my meter. Ordered an OEM NICHICON 100UF 250-VOLT Capacitor for $1.85 on ebay and replaced it - but before doing so I tested the NEW Capacitor with meter and it tested as 99UF - So I re-soldered it in and BINGO ALL FIXED!!! Problem was bad Capacitor on Power Cube!! FIXED FOR UNDER $2.00 !!!
