Dacor Oven Won't Preheat
My Dacor oven ECS227 would not preheat. Most website advice was the High Temp Cutout needed to be reset. That was not my problem. I found a schematic for the oven and determined the relay that controls the power to both the Broil and Bake elements was not conducting. I could hear the relay operate but the voltage for the two elements was not on the output side of the relay. I ordered a new Relay Board (92029) for $200 and after replacing the board the oven worked except it started smoking from the panel area and the smell was that of an electrical overheat. Further investigation revealed one of the slip-on connections on top of the relay was sparking and generating heat in the range of 150 degrees (measured with a IR temperature meter). It was melting the plastic around the connection which was the source of the smoke and the smell. I removed the wire, compressed the connection points a little, reconnected the wire and all is well. The plastic around the connection became very brittle from the heat and broke off while I was working on the wire connection but it still works. I found you can purchase the relay itself for about $5, so I did that just in case this should happen in the future. I will repair my old board and have it ready to go for a future replacement if needed and will also replace the connection clip at that time. The relay can be ordered from Mouser Electronic - their part number 655-T9AP1D22-18-01. The relay is stamped T9AP1D22-18 Potter Brumfield. Hope this helps anyone else when the resetting of the High Temp Cutout does not solve your problem.
