Scott,
The “ACV” shown on the meter control panel means “Alternating Current Voltage”. You have to turn the mode switch on 200 scale for this test.
Because you are not very familiar with safety rules to work under the power, it’s going to be probably better (and safer for you) just to replace the control board.
- The part number for the control board is [COLOR=#0066cc]AP3767567[/COLOR]
