PID Went Out, replaced with back up, now contactors not cycling. Need help

Posted by admin on September 5th, 2010 at 02:51am

Had a oven full of suspension parts, and noticed the PID from (Ted’s) was flashing a err/alarm across the display, and noticed the temp had fallen to around 300. Long story short, I replaced the the PID with a back up auberins pid 2362 I purchased, for this very reason.

The back up is a little different, but we got it wired in and all was good…
EXCEPT the contactors will not cycle… I hear them come on when I flip the heater switch on, but again, they wont cycle and it has be frustrated.. Have a ton of stuff to get done.

The control box I have is Ted’s. Everything is exactly as sent to me, except for the new PID..
Where is a good place to look first to trouble shoot?

I noticed Teds PID came ready to go. Simply flip on the power, wait until the out light comes on, then flip the heater switch on…
Shouldnt this PID be the same.. I see the out light come on, and it flashes, but the temperature keeps on going.

I did ohm out the contactors and all is good there as well.
Thanks for any help!
