My built-in Westinghouse POS oven doesn't have gas flow. There is gas to the stove top - so the problem is either with the oven not opening the valve, or maybe a blockage in the line from the T-junction. This place is in northern Adelaide so can anyone recommend a plumber or gasfitter that can look at it on the cheap - I'm basically looking for evidence that it'd be a warranty issue and not a plumbing issue. Otherwise I could end up paying squillions for some Electrolux dudes to tell me it's not their problem. Cheers.
