Hotpoint RGBS400DM1BB free standing gas range Parts

On the Hotpoint RGBS400DM1BB gas range, most ovens do not use a standing pilot that you relight; the oven burner is typically lit by an electronic igniter when you set Bake or Broil. If the oven will not light, we focus on restoring gas flow and checking the igniter system using the RGBS400DM1BB owner's manual.

• Turn the oven control to Off.
• Let the oven cool completely.
• If you smell gas, do not try to light anything; turn off the gas supply and ventilate the area.
• Keep the oven door closed while you troubleshoot ignition.
• Disconnect power before inspecting wiring or replacing parts.

1. Confirm gas is on at the house shutoff valve.
2. Check the regulator lever: this model’s manual notes that bake and broil may not light if gas flow is shut off at the regulator behind the drawer area near the rear gas line connection.
3. Try Broil for 30 to 60 seconds, then Bake. A weak igniter sometimes shows up faster on Broil.
4. Look for igniter glow (through the broiler drawer opening on many ranges):
   • Glows but no flame: igniter may be weak.
   • No glow: power, wiring, or control issue.

If the oven is not igniting reliably, these are the most common repair paths for RGBS400DM1BB:

• Bake burner ignition WB13X40208 (oven igniter)
• Range gas valve and regulator assembly WB21X38548 (gas flow control and regulation)
• Range oven temperature sensor WB20K10015 (can affect heating behavior and temperature control)

A gas oven that will not ignite is usually a gas flow or ignition problem. Fixing the root cause helps prevent delayed ignition, poor baking performance, and repeated no-heat failures.

On the Hotpoint RGBS400DM1BB gas range, common signs of a failing part include burners that light unevenly, flames that turn yellow or get unusually large, persistent clicking at ignition, or an oven that will not bake or broil even though surface burners work. Confirm safe operation steps in the RGBS400DM1BB owner's manual.

• Top burners do not burn evenly (often a cap or burner head seating issue)
• Burner slots look clogged (debris causes uneven flame and slow heating)
• Flames are very large or yellow (air-to-gas ratio problem)
• Surface burners light but bake/broil do not (oven gas flow may be shut off at the regulator)
• You smell gas near the range (turn off gas supply and stop using the range)
• Oven temperature seems off (can point to a sensor or ignition issue)

1. Make sure all knobs are fully in the OFF position.
2. Remove and reseat burner caps so they sit flat and centered.
3. Clean burner ports/slots (after parts are cool and gas is off).
4. If flames are yellow/oversized, increase ventilation and stop using the range until the fuel/air setup is corrected.
5. If surface burners work but the oven does not, check whether the oven gas flow lever at the regulator is in the open/on position (location and access details are in the manual).

Uneven flames, yellow flames, or an oven that will not ignite can signal incomplete combustion or improper gas flow. Addressing these symptoms quickly helps protect cooking performance and supports safe ventilation practices.

A gas stove (gas range) like the Hotpoint RGBS400DM1BB is made up of a cooktop with sealed surface burners plus an oven system that uses gas ignition and temperature sensing to bake safely and evenly. For model-specific features and safety rules, use the RGBS400DM1BB owner’s manual.

• Surface burners (sealed burners) that mix gas and air to create a flame
• Burner caps and burner heads (must sit correctly for even flames)
• Burner grates that support cookware
• Control knobs and the manifold behind them (routes gas to each burner)
• Orifices and orifice holders (meter gas flow to each burner)

• Bake burner and ignition system (lights the bake flame)
• Broil burner (top heat for broiling)
• Oven temperature sensor (helps regulate oven temperature)
• Oven racks and rack supports
• Oven door assembly (glass, hinges, and door gasket to help seal heat)

Knowing the major parts helps you troubleshoot safely. For example, the manual notes burner caps must be seated correctly for even top-burner flames, and it also warns against blocking airflow (such as covering openings with foil) because airflow problems can create unsafe combustion conditions.

• Turn all burner knobs to OFF before inspecting anything
• Let grates and burners cool completely before touching
• Watch the flame, not the knob; flames should not extend past the cookware bottom
• Never cover cooktop or oven airflow openings with foil or liners

On the Hotpoint RGBS400DM1BB gas range, the oven igniter is mounted inside the oven cavity at the bake burner area, typically along the bottom where the bake flame comes from. You access it by removing the oven racks and lifting out the oven bottom panel to reach the burner and igniter.

Most “oven won’t heat” igniter questions are about the bake igniter, not the broil burner.

• Bake igniter: under the oven bottom panel, next to the bake burner tube
• Broil igniter (if equipped): at the top of the oven near the broil burner
• Gas regulator shutoff lever: behind the drawer compartment near the rear gas line connection (this can stop bake and broil from lighting)

1. Turn the oven control to Off and let the oven cool.
2. Remove oven racks.
3. Lift out the oven bottom panel (some panels use screws at the rear).
4. Locate the bake burner; the igniter sits beside the burner ports.
5. If you are replacing it, match the connector style and mounting bracket.

For model-specific panel removal details and diagrams, use the RGBS400DM1BB owner’s manual.

If the oven takes a long time to light, clicks but does not ignite, or never heats, the bake igniter is a common fix for this model.

The igniter does two jobs: it glows hot enough to ignite gas and it helps the gas valve open. A weak igniter can glow but still fail to light the burner reliably, causing delayed ignition or no heat.
