Hi @joe1sr ,
 
Is [https://www.aliexpress.com/item/100pcs-IN5408-1N5408-3A-1000V-DO-27-Rectifier-Diode/32450788313.html?spm=a2g0v.10010108.1000001.7.2f916a67iwXMDk|this] what it looks like?
 
If it is, it is a power diodediode, IN5408.
If it is, it is a power diodediode, IN5408.
 
You can test if the one you have is OK by using an Ohmmeter. (test with the power totally disconnected from the device)
 
It should measure low resistance in one direction and high resistance when being measured in the other direction by reversing the Ohmmeter’s test probes.
