Thank you for the suggestions. Will poke around some more to see what I can find.
I apologize ahead of time for my lack of knowledge in testing electrical components…
- Getting roughly 190 kOhms at the load & neutral on the psu connections
- Getting roughly 7kohms at the positive and ground on the psu connections
- Reading 0 at the ground to power prongs
- Frame to ground prong is roughly 120 ohms
When testing the continuity using the “beep” continuity test, I am not getting a beep. Shouldn’t the metal frame be grounded as well?
Edit: Also, just to add. It trips the GFCI when not even running…I simply plugged it in, turned it on and after 5-10 minutes it tripped. Never sent any prints to it or any other commands.
What we are trying to measure is isolation from mains power to ground
With the power switch on measure from the safety ground pin to either of the power prongs
(we are looking for MILLIONS of ohms, the 200 or so ohms difference between the 2 legs of the AC input won’t show on a typical meter)
I’d warm it up to the point the GFI would trip. Yank out the plug and measure quickly. From AC to safety ground should be more than 20 million ohms.
Bad part is, if it’s has good isolation your meter won’t change at all.
If the display shows numbers that’s a fail with most moderately priced meters
