I used to have the same issue with reed switches on one product we ran. Same oven too. We ended up rigging up an "umbrella" with two titanium stiffeners and bare PCB as the roof. It was hokey but it worked.

Good idea DWL, "Umbrella" thing works to solve this problem temporarily. But do you think it will cause any damage to hitter or heat zone?
