Oven wont turn back on after turning off circuit breaker

There are two causes that come to mind. Either you have a build up of static electricity in your body and you are discharging it into the oven, causing the controller to reset, or something in the oven is shorting out to the chasis causing you to get shocked when you touch it.

Do you commonly get static shocks anywhere else in your house? This is common in northern climates in the winter when everything is really dry. Often you can improve this by increasing the humidity in your house.

If you do not have static issues elsewhere then it is likely that something is wrong with your oven in the form of a short. I would advise not to use it any further and have a service person come back and check it more carefuly. Heating elements failing is a common cause of this.

Sounds like there are two options.

Option one is to replace the existing breaker because you think its defective. This option is good if you know that you're not using enough power to trip the breaker so something else must be going on. However, it doesn't sound like this is the case.

Option two is to run a new dedicated circuit to the room to handle the extra load you need to run. If you're using too much power, this is the only right option. The breaker should never trip, so you shouldn't need a remote way to reset it.
