Morning I need help please regarding my gas oven (Beko SCG7530). The problem is when i turn the gas knob on,(push and hold for say 10 secs)the oven works fine,but as soon as the knob is released the gas oven goes out! All the hobs on the stove work fine its just the oven/grill. I've looked at several forums which are confusing. Could it possibly be the coil or Thermo coupling? If so can purchase the parts & get someone to fit them?. Please help Thanks Sugar

Sugar,
Sometimes it takes a minute or longer for the thermocouple to get hot enough to send the correct voltage to the main part of the gas valve to get it open & the burners to light. If after a few attempts of turning the pilot knob to off, waiting a couple of minutes and then going thru the lighting process, your problem is the thermocouple. Most repair companies will NOT install YOUR parts because of the liability & warranty issue. The best bet is to call a repair co & explain what the problem is & tell them to bring a thermocouple with them. Sears or calling your local BBB is your best course.
