Hi. We have a Technica TU950ME8 oven which seems to short out. If it runs above 180 degrees for more than 45 mins the clock will start to short out. It flickers on and off and will then cut the power to the oven ( gas cooktop is fine). You can also hear an electrical shorting sound while it's happening. It does not trip the circuit breaker to the house though. Any help would be great, thanks. Claire
