We have a small oven above the Dometic fridge / freezer. Until recently it worked reasonably well but toward the end of our last trip (11 weeks) it started to exhibit low yellow tipped flames. All other gas powered items (Alde boiler, gas hob, etc.) are working well so I assume the gas supply is okay. I have heard that these ovens are not the best of equipment and would agree but this seems to be a new problem. Any thoughts?
