Auber ssr problem

Can I assume that if I have continuity through my ssr when there is no power to it that it is not a good thing? I am having problems with the temps going too high. It continues to rise even when the PID is not sending a signal. One of my ssr's does not have continuity when it is off but the one I am have problems with does.

That tells me if the SSR is switching when it is energized. I think my SSR is closed when it is not energized.

 

I checked the ssr last night to see if there is much voltage on the output when the pid was not sending a signal and there was over 120 volts going to the element. That was with the temp over what the pid was set at and no light on the ssr.

 

That could be normal - depending.!

How do you have the element wired? 120V or 240V? Are you measuring the voltage across the element terminals?

 

It's a 120V element wired with 120v. I was checking across the hot and neutral going to the element.

 

Ok. Then the element is being powered and that means the SSR has failed.

 

Kinda what I thought. The temps just keep going up even after it passes the set point. Thanks, P-J!

 

I had one of these auber ssr melt on one of the contacts recently as well. I dont think the are the best quality of ssr around. The replacement which was three times the price looks to be better designed. I have had no trouble with their pids though.

 

That is a good example of a problem when using crimp on connection lugs for a high current application. I do not trust the crimp connection so I solder it also' after the crimping is completed. I've had the lug connection overheat to the point that the metal began to arc.
