My oven is just under 4 yrs old.
When I switched it on last night I heard an unusual noise and realised that the cooling fan seemed to be struggling to get going.
After 5 mins or so it seemed to kick in and continued working normally. When I switched oven off continued as normal, sounding as it usually does.(When I test the oven and switch it on and off within a few minutes the fan makes a strange whirring noise when off)
Is it dangerous to continue to use the oven if the cooling fan is on its way out(as according to the book its to keep the exterior cool). Clearly the gas is still ok and I could therefore cook.
