Oven heats up but baking is always undone!

SOURCE: Dacor Oven - convection fan stays on while on "bake" setting

Question: does the unit appear to hold the correct temperature? Most convection units only turn the heating elements on and off...not the fan. If the unit is reporting operating temp and then taking other direction...and it is cooking right...you're done.

We have the same issue anc alled Dacor. I seems as there is a problem with the oven as it was built with a faulty or missing temp control part. They have a fix for this problem by installing a temp control kit. you need to work through the warrantee group

SOURCE: dacor oven ECPS127S will not heat after self clean

the problem was fixed by opening the panel between the oven cavity and the touch panel just behinf the door. you can look through the grill but to trip the reset you must unscrew the panel. you will find the reset back behind the wires Looks a red button nestled on top not very open but it should be there> i do have to say i found a step by step description on this site. but right now i can't tell you who exactly he was.

HI - I just had the same problem - repairman came and reset the breaker in the oven which "tripped" (even tho I havent used the lower oven in months).  Read posts here on other Dacor ovens which explain how to get to the reset switch to avoid having $150 in repair costs - I have not tried that myself tho but good luck!

SOURCE: Dacro Wall oven (electric) does not heat past 345 degrees on bake or convection bake but broiler works and bottom oven works fine (for bake, convection bake and broil).

it could be the oven temp sensor rod located near the top of the inside of the oven,or possibly the bake element has a hot spot on the element and can no longer pass enough current thru this spot to correctly heat to your settings a hot spot on the element will look discolored in this area
