When foods come out burned, soggy, or unevenly baked, it generally means heat isn't being distributed evenly throughout the oven, it's escaping out the door, or the controls are out of adjustment.
When an oven doesn't maintain the set temperature, first make sure no one is allowing the heat to escape by opening its door. If not, the oven control either needs to be re-calibrated or replaced.
Our technicians are factory trained to service and repair most makes and models of ovens. Please call (888) 431-3472 if you require assistance or would like to schedule an appointment.
