We have the same 09 BH 3670RL, we went through 2 half-time ovens and then switched to their microwave. It did not last either, so we switched too a dometic micro wave. The only problem is the face plate doe not work. We bought the face plate with the dometic, but had to re-work the opening. Which is hard to match the stain, we got close but not exact. I still have the old pc. we took out, plan on making new ones when I get back home. We used plywood because we where in Tenn. and short on time and had to leave.
