Regarding holding the safety down...
In 2004 I seem to remember jamming the safety in the depressed position so that the oven would be useable. It was a somewhat desparate attempt to get through the weekend and use the damn oven.After speaking later with Seaward, and learning of the potential benefit of cleaning the pilot orifice, I did that action the following weekend. Results seemed positive, the oven stayed lit, and I thought the problem was solved. However, 4-6 weeks later the problem reappeared. Now it was close to winter haulout so we just did without using the oven and cooked more on the BBQ.At the beginning of 2005, I cleaned the orifice again and moved the thermocouple closer to the flame of the pilot. I *think* it seemed a little better, but the pilot was still going out and the safety shutting off.I keep coming back to the Seaward statement about the safety valve and thermocouple unit:"It either works or it doesn't work. It is not something that is prone to be intermittent. And it is a low failure rate item. We have very little trouble with them."Based upon those statements, it doesn't look like a good bet to replace the safety. But....???
