How to fix surface burners that aren't heating properly on your Fisher & Paykel gas range
If neither the oven burners nor the surface burners heat properly, then check the gas supply going to the range for properly supply pressure. Get help from your local gas supplier if supply pressure is deficient. A failing pressure regulator in the range can also prevent oven and surface burners from getting the right amount of gas. You may need to replace the pressure regulator if the gas supply to the range is good but gas pressure going to the oven and surface burners is weak.
For an individual surface burner not heating properly, check for and clear any clogs from the burner orifice. A failed surface burner control valve can also prevent a surface burner from heating properly. Replace the burner control valve if it won't control gas flow properly.
