this could be a problem at the gas pressure street level (utility company) this may also be a bad gas regulator in the range itself which would be covered under the warranty, i would first have your gas company check the street pressure and if it is ok call G.E. and have them check the range, theres no reason you should have to attempt a fix yourself, hope this info is useful, thanks Bryan
iHAVE THE GAS CO. SCH. TO COME UOT TOMORROW TO CK.THE PRESSURE AT THE RANGE. Today however the whisleling noise stopped as of now,buy it has done this previously. If the pressure is ok Iassume Iwill have to get the gas valve on the range replaced?? What part do I look for if that is the problem ??
