Oven heats very slowly or cannot reach higher temperatures (e.g., stuck around 250–300°F).

Safety first: Turn off gas and power before disassembling. If you suspect a gas supply issue, contact a licensed gas technician.

• Observe flame: With the bottom panel removed, start a bake cycle and observe the burner flame. It should be strong and mostly blue. Small, weak, or uneven flames indicate a gas flow issue.
• Clean burner and orifice: Turn off gas and power. Remove the burner and clean ports. Carefully remove the orifice and clear debris with compressed air (do not drill or enlarge).
• Check igniter: A weak igniter can cause delayed or incomplete gas valve opening. If the igniter glows dull or takes a long time to light the burner, replace it.
• Regulator and pressure: Ensure the range’s gas regulator is correctly oriented and not converted incorrectly. Have a technician verify inlet and manifold pressure.
