Joe for Model Number RBD275PDB14 Both the top and bottom ovens take at least 20 - 30 minutes to preheat to the desired temperature. When they are fully preheated, the temperatures are accurate. The preheat timer buzzes after about ten minutes but the oven has only heated about half of what is was preset at. Does this indicate a bad heating element or another issue? Thanks.
Answer Hello Joe, You should first flip the breaker to the oven off and back on to make sure half of it is not tripped. The next suspect will be the connection in the junction box where the cord from the unit is hardwired to the home wiring. If this is good, the next likely suspect is the control board WPW10438751.

Answer Joe, Everything sounds fine and there are no issues. It still takes 20 to 30 minutes to "properly Preheat" an oven. The newer controls, are designed to sound an alarm in a specific amount of time, and/or, the first time the sensor registers the resistance/temperature in the oven cavity. This is referred to as "tempering" the oven/cavity, it's not a preheat cycle. The "tempered" oven will operate and cook just fine in most cases(95%), but if you're cooking something special, delicate or a specific recipe, you'll want to properly preheat the oven (20 to 30 minutes).
