The Issue - My Dacor ER48DSCH/LP dual fuel range large oven temperature won't regulate after installing a new bake element. When the oven is turned on and a desired temperature keyed in, the temperature climbs into the 500's. At that point I shut it down. There are no error codes and the small oven works fine.
Background - The range is about 11 years old and the original relay board was replaced by me about 4 years ago. The original one was sent out to be repaired but hasn't yet been reinstalled. I have to do my own service work since there are no Dacor techs who are willing to drive out to my rural location.
The large oven hadn't heated properly for years. By design, it beeps when set temperature is reached. But the actual temperature would be much lower and it took about 45 minutes to come up to set temp. About a month ago I replaced the temp sensor and high temp limit switch which made no difference. The resistance readings for the old and new temp sensors were the same so I don't think there was anything wrong with the old one.
A few days later the 50 amp circuit breaker tripped while the oven was heating up. I reset it, turned the oven back on, and touched the breaker body to see if it was getting warm. It stayed cold but tripped again so I figured it was OK. Next I removed the bake element cover and found that one of the push-on female wire connectors to the inner heating element was burned off. The bare wire was touching another terminal. One of the outer element connectors was half burned away. That explained the breaker tripping and slow heating since only the outer element had been working.
I replaced the bake element with a used but like-new element (new ones are impossible to find since Dacor/Samsung has discontinued that item as well as many others. So much for customer service). New heating element wiring harnesses were also installed. Upon startup both elements heated up quickly and glowed orange like they should. The breaker didn't trip and it seemed like all was good. Not so! Now the temperature doesn't stabilize when set temp is reached. It keeps climbing into the 500's. I don't hear the relay kicking on & off to hold set temp.
Diagnostic - There are two main circuit boards - the oven control board behind the front LCD screen and the relay board underneath the stove top burners. Here are some of my thoughts:

Diagnostic - There are two main circuit boards - the oven control board behind the front LCD screen and the relay board underneath the stove top burners. Here are some of my thoughts:
- The relay that controls the large oven heating element circuit could be stuck closed. Maybe the electrical surge that tripped the breaker welded the contacts shut?
- Maybe the new temp sensor got damaged from the power surge?
- Any of the circuit board components that receive the temp sensor signal and send it to the relay could be compromised and always sending a signal to "stay on".
- The oven control board could be sending a high temp demand signal even though it's programmed for something much less.
