  1. I appreciate your input Dick and Niel. I'm a newbie to this stuff but have a grip on herding electrons and measuring stuff. My expertise is off grid power systems and I've recently moved to a place where maybe I'm the most qualified person to maintain kilns. This kiln is at about 90 firings since new. In my experience when one thing fails replace them all (relays). And also elements... They all still work but they're getting bunched up. I wonder if best practice is to replace them all soon. It seems quite expensive and sad when the kiln fails around here.
  2. Dick... nice to hear from you that relay malfunction is common. I know my way around high voltage, nice to know that relay malfunction is common. Neil ~ thanks, that explains a lot and makes a load of sense. Ordering relays on Monday ;-). I suppose it's good practice to replace them all if one failed? Thank you both.
  3. I'm new to this, I'm trying to help with Kiln repair. My friends have an L&L easy fire kiln. Last firing it could not get up to temp. It seems to me the middle elements are not getting power, it appears the relay is the problem. The relay is a double pole relay. (does it need to be?) Checking with a meter, half the relay still works. My thought is to just bypass the other half so that one side of the relay could energize the element. I wonder why they are double pole relays to begin with, I'm inclined to parallel the poles for all the elements so that there is redundancy. Meaning... one end of the element is always connected to 240V, the other end is turned on and off by the relay. I don't understand why why two connections are necessary.
