Plate heating speed issue

I'm having an issue with my 200mm V-Core 3.1 plate heating up slowly. It takes a LONG time to get anywhere near PLA temps, PETG temps it seems it can't even reach, and usually shuts down with the error that it was taking too long. (I have calibrated multiple times) It seemed to work normally for about a week after building it, then this started. (I've had the printer for awhile, I got one of the first numbered batch) A little backstory, I have a 500mm V-Core 3.0, and a V-Minion. The 200mm V-Core 3.1 is wired up exactly the same as my 500mm V-Core 3. The 200mm actually has the most wattage for the area of plate, but the 500mm heats up MUCH faster. (and that's only using 80% power due to being in the US with 120v) I'm guessing there is something wrong with either the heating pad, or the SSR? (or the board?) Is there a way I can diagnose them before buying replacements? (I'm getting ready to order the 3.1 upgrade kit for my 500mm) Thank you in advance!

Kind of doubtful it is the heating pad as that is just a big resistor. I would disconnect the wires to the SSR and use a multimeter to test you are getting 24v out. If that is good, then disconnect the bed from the SSR and test the SSR output with a multimeter and any neutral wire. If all those check out then look into testing the heating pad

Welp. I measured 24v into, and 120v out of the SSR. I was looking at the pads on Ratrig's website, no idea what made me decide to peel back my insulation layer and look, but I found the problem.

How the heck did I not see this when I built rip for the help, and getting me to think about it.

Lol 220v in 120v land is indeed a problem

Which would explain why it works fine, but has "no balls"
