This happens about two are three minutes after the breaker is turned on. I have 50 Wt breaker. I have thoroughly checked the wiring from the oven to the breaker box. THe breaker trips when the oven is on and went it isn't. I have checked the plug connection to the oven and it is fine. Also, the receptacle for the oven. It does not have anything else plugged into it. The model is RF3750XPW 0. Thanks for any help.

" and went it isn't" if there is no short then you need to replace that breaker

Check your wires with an ohm meter with the power off to the wires and see if there is a short to ground. Then disconnect oven and do the same check until you find the short. You can burn down your house just changing breakers without finding that short. You may need to pull new wire. Look in each junction box and see how the wires look. Check wiring in sections until you find the short. DrTom4444
