Looking for some DIY help. This is a Magic Chef natural gas range oven (Model # CGR3730ADH) issue. When the oven was on it was making an on/off vibrating noise. The gas regulator was replaced. Seemed to work for a short while. Now it sounds like the gas/burner cycles on/off and on/off without letting the oven get up to temp. Seems to take a long time to finally reach the desired temperature. What could be the possible problem? There are not many parts to this stove. The top 4 burners are work great.
