Most likely the problem with your oven is a bad control board. - The part number for the white control board AP3095480 - The part number for the black control board AP3095479 - Here are the break down diagrams for the Whirlpool oven Model RB260PXYB0Gene.

I have set the temp at 405. Oven reaches set temp and stays for an hour them falls back to around 200. It does not shut off and on. I have calibrated the over both + & - the allowable. Last night I turn the power off hoping a error code would appear. Nothing showed up. I have removed the door lock. Would this be causing my problem?

What temperature was set? Does the oven go on and off? Normally, after the set temperature was reached, the oven goes off, cools down for about 30 degrees and, then goes on again. It does it as long as the oven control stays on.

Whirpool RB260PXYBO. This is a built in 30" electric oven. The oven temp does not hold at the set temp. Oven will reach set temp and stay there for 45 min to an hour. Then temp gradually falls to 230 to 250. I have already replaced the sensor. Where else should I be looking?:confused:
