A brief tutorial
Thanks, Mike, I seem to remember something like an XY... cap as the recommended type, do I need to replace with the same exact value, ie., .022 uf?
Yes, do NOT go larger (look up capacitive reactance to understand why). Get a 600V rated cap too.
A "death cap" should be replaced by a type "Y" or dual rated "X/Y". Not sure what you mean by 600V but these caps generally carry an AC rating when listed by safety agencies. 250VAC is sufficient for US mains. 600VDC may or may not be. Also, there's a limit on AC current thst can be passed and still be considered safe. I recall (so don't quote me on this) something like 0.3 or 0.4mA which @ 120VAC equates ~ 0.008uF max. Point here is that it's worth a little research to replace with safe value and that 0.02uF is probably too large by today's standards.
