Product review (5 stars): Works like a champ
I was unable to control my oven temperature. The temperature just kept climbing until it overheated no matter what I set the temp to. It was overheating so hot that it set off its internal overheat alarm. I saw that a component on the circuitboard was burnt. So I replaced the relay board.  The oven still did not work but my symptoms were different this time. I kept getting some sort of error on the oven display. I then changed the oven control board and my oven was working again. Great product.
