Well Goonie, I don't know which model you have. We have the Dometic which we've had replaced because it didn't come up to the set temperature. What we've found is that we have to set it about 25 degrees higher than we want. Also, when we do the preheat, it needs to go about 10 minutes longer, after the signal goes off. Our new one is the same as the previous one. Ours cooks and bakes just fine if we use these guidelines. We don't have the propane oven so we have to use the Convection oven. Being fulltimers and my DW loves to cook, it gets lots of use.
