I purchased a bake element for my Dacor ECS130 oven from Appliance Repair Pros in November. Now the oven will not heat up at all. I checked the temperature limit switch and the reset button is not popped out. I also confirmed that the BA relay is getting 240 volts (NO COM and BA Relay) when in bake mode and it is clicking like it is trying to activate the element, but there is no heat. The oven will also not go into broil.
Is it possible that the bake element has failed? Is there a way I can check to see if the element is working properly? But with it not going into broil is it also possible that the Oven Hi Temp Limit Switch has failed? Or do you think the relay board or controller board is bad?
A local repair guy quoted my wife $800 to fix it, but he was not specific about the problem. And a new oven is WAY too much money!
Help!!
Check your high limit for continuity. Remove one wire and check it. If it shows a dead short or continuity its okay.
Your bake element should show very low resistance when tested across it’s two terminals. Somewhere around 10 to 40 ohms I would think.
I’d check the high limit, the bake element, the wiring, and the relays and back side of the board. You might have a trace burned off.
I might also check the oven latch switches. Sometimes the element wiring is ran through them. I don’t know if yours is wired like this or not.
Thanks for the reply. I ran some more checks tonight.
-
The high temp limit switch works correctly, as evidenced by the fact that there is continuity when I remove both wires and check continuity across both terminals.

The bake element is good. It showed about 25 ohms.
Here is what is interesting: I removed the bake element and connected my meter’s leads to the wires that would normally connect to the bake element. I set the oven to bake mode. The meter was alternating between 120 volts for about 35 seconds (relay click) and 0 volts for about 30-35 seconds (relay click). This just kept repeating.
By the way, I also checked terminals 2 and 5 on the main control board. When in Bake mode, it would read 24.5V and when the relay would click it would got to 25.3V. This would alternate each time the relay would click. When I turned off the bake mode, those same terminals were reading 28.5V.
Does that tell you anything useful?
I’m thinking it must be the ERC.
By the way, I checked the schematic for the oven, and the wiring for the bake element does not go through the door latch mechanism.
When the relay clicks, you should read 220 to 240 volts AC across the two terminals on the element.
120 volts will barely make it warm. You need to find out what happened to the other half of the voltage. Just be very careful around electricity.
I don’t know what terminals 2 and 5 on the main control board go to or do. Sounds like relay control voltage.
