Abbey Spectrum 418

[jaragama]

Hey all, I have just purchased my first caravan, an Abbey spectrum 418 I was told a 2002 but checking now I don’t think they even made that year so could be a 2001 or 2000. Have got most things working but the oven switched on once and now won’t light at all, same with the grill. The hobs works fine. And weirdly enough when I tried the oven again or grill the alarm went off which is an IDM-3 alarm? No idea what it’s for or why it would go off. Also on a side note, is there a basic check list I should maintenance wise? Sorry to ask so much but complete beginner and want to make sure I look after her well. Thanks Michael
