SSR not switching bed power

Hi guys i can´t figure out why my ocotopus is not switching the ssr anymore i have 5 days and 5 hours on my vcore 4 500 hybrid, worked flawlessly it suddenly stopped working during a print " bed not heating at expected rate" the ssr works i tested it with a power supply The cables are all good i checked them and also measured The Fuse is also good But the octopus is not giving power to it

the polarity is correct And i already changed the octopos to a new one because i had it on hand i tried switching the pin [heater_bed] heater_pin: PA2 this pin is also not turning on Motion system is working tried reflashing the board, didn´t change anything

Did you check with your hand if the bed gets warm? Maybe its just the thermistor wich is bad? Otherwise its the bed heater itself according to your checks

no the ssr has a status led that doesnt turn on when i power it directly it turns on and gets warm

Did you though of replacing the wires? Wich lead to the ssr?

I put 24v at the crimped ends and it worked so no i did not change the wires Is there a way to manually switch PA1 on on the octopus?

Do you have a multimeter/voltmeter?

I found the problem The 4028 pwm fan shorted the 12v rail on the octopus I unplugged it and everything works fine now Thanks
