My LED driver isn’t working because this fuse is burned out. How do I identify it and find a matching one?

Thanks!

That’s not a fuse, it’s a diode.
How do you know it’s burnt out?. How did you test it?

Oh! That is super helpful. I tested it with continuity mode in my multimeter. It looks ok in diode testing mode. I will continue to troubleshoot.

Thanks for the quick response!

Approx 0.5 - 0.7 in one direction only and 0L the other?. All is good with it.
What’s the main issue?

Hello,

As there is ZD next to the diode, it is a zener diode.

Thanks folks! The overall problem is that LED lights in my rangehood aren't working. I misdiagnosed it. The driver seems to be producing steady voltage. One of the LEDs is bad and since they are in series, both LEDs are off. I just need to buy a new LED.

Unfortunately, the manufacturer hasn't specified the specs for their LEDs and LED driver, so I will have to keep buying from them with very high markup. See https://kobe-range-hoods.myshopify.com/products/led-driver-c1-0402-d001 and https://kobe-range-hoods.myshopify.com/products/led-lights

Thanks Martaine2005! I am located in San Francisco Bay Area. I will buy their LED this time and then do a surgery on the old LED to prepare for the next time.
