Hotpoint RGAS300DM1WW gas range Parts

On a Hotpoint RGAS300DM1WW gas range, the most common signs of a faulty part are burner flames that look wrong (yellow, uneven, or too large), burners that click constantly, or an oven that will not heat reliably. Treat any gas odor as urgent and stop using the range.

Common symptoms to watch for

• Persistent clicking even after a burner lights (spark system keeps trying to ignite).
• Yellow, lazy, or uneven flames instead of steady blue flames.
• Burner won’t light or lights slowly, even when the knob is held at LITE.
• Flames extend past the cookware or flare up unexpectedly.
• Oven won’t heat or heats inconsistently (often tied to ignition issues).
• Gas smell near the range or in the kitchen.

Quick checks you can do safely

Follow the lighting and burner assembly guidance in the RGAS300DM1WW owner’s manual.

• Confirm burner caps and grates are in the correct locations and fully assembled before lighting.
• If one burner is set to LITE, remember all burners may spark; that is normal.
• Use cookware that fully covers the flame; do not let flames extend beyond the pan.
• Do not run a burner for long periods with no cookware on the grate.
• Do not use a wok ring or after-market stove-top grill; restricted airflow can cause unsafe combustion.

Symptom-to-part area guide

Symptom	Most likely area	Example part to inspect on this model
Burner clicks continuously	Ignition electrode or wiring	Electrode top & harness hv WB18X30975
Oven won’t heat, no ignition	Oven ignition system	Igniter glowbar WB13X30972
Oven light not working	Bulb or socket	40a15bulb 40A15, range light socket WB08T10026

Why it matters

Abnormal flames, restricted airflow, or ignition problems can lead to overheating, poor combustion, and unsafe operating conditions. The manual also warns against actions that can damage gas tubing or block airflow (such as lifting the cooktop or using foil on the cooktop/oven bottom).

A gas stove (and a full gas range like the Hotpoint RGAS300DM1WW) is made up of the cooktop burner system (grates, burner heads/caps, igniters, and knobs) plus the oven cavity and its safety and lighting components. These parts work together to deliver gas, ignite it, and control heat safely.

Main parts you will see on the cooktop

These are the components you handle most often:

• Burner grates (support cookware and protect the burner area)
• Burner caps and burner heads (shape and distribute the flame)
• Electrode/igniter (creates the spark; you will hear clicking when set to LITE)
• Control knobs and gas valve shafts (turn gas on/off and adjust flame)
• Orifice holder and orifice (meters gas flow to each burner)

The RGAS300DM1WW uses sealed surface burners; burners should be fully assembled and in the correct location before operation (details and diagrams are in the RGAS300DM1WW owner’s manual).

Oven and lower area parts (common on gas ranges)

Most Hotpoint gas ranges include these oven-related components:

• Oven cavity and oven bottom panel
• Oven racks
• Oven burner and ignition system (glow bar style on many models)
• Gas safety valve/regulator components
• Oven light system (bulb, socket, lens/retainer)
• Storage drawer or warming drawer (varies by model)

Parts on this model page you might recognize

Here are a few examples of parts listed for the Hotpoint RGAS300DM1WW:

Area	Example part	What it does
Oven light	40a15bulb 40A15	Lights the oven interior
Oven light	Range light socket WB08T10026	Holds and powers the bulb
Cooktop	Range surface burner grate bumper (WB02X24790)	Cushions the grate and reduces rattling
Oven ignition	Igniter glowbar (WB13X30972)	Heats to ignite gas at the oven burner

Why it matters

Knowing the major gas range parts helps you troubleshoot faster. For example, clicking with no flame often points to burner assembly, moisture, or ignition issues, while an oven that will not heat often points to the igniter or gas safety components.

If you can’t find a part for your Hotpoint RGAS300DM1WW gas range, we recommend confirming the full model number and then using the parts diagrams and manual to match the exact component name. If it still doesn’t show up, our parts specialists can help you identify the correct replacement.

Quick steps that usually solve it

• Confirm the model number is RGAS300DM1WW (not a similar series number).
• Use the exploded-view diagrams to identify the part by location and description.
• Search by the part name you see in the diagram (for example, “light socket” or “leveling leg”).
• If you have an old part, search by the manufacturer part number printed on it.
• Check for common naming differences (example: “igniter” vs. “glowbar”).
• Review the RGAS300DM1WW owner’s manual for part and accessory references and troubleshooting clues.

Common reasons a part “isn’t listed”

What you’re seeing	What it usually means	What to do next
Part name doesn’t match what you call it	Diagram uses a different term	Try alternate terms (socket vs. receptacle, cap vs. burner cap)
Multiple versions of the same part	Color, size, or revision changes	Match by location and description in the diagram
You’re looking for a sub-part	It’s sold only as an assembly	Search the assembly name from the diagram
Model number is close but not exact	Parts vary by suffix/revision	Re-check the rating plate and use the exact model

Parts on this model that are often searched by a different name

• Oven “light bulb” is commonly searched as a “range bulb” (example: 40a15bulb 40A15).
• “Light socket” may be listed as a socket or receptacle (example: range light socket WB08T10026).
• “Igniter” may be listed as a glowbar (example: igniter glowbar WB13X30972).

Why it matters

Gas range parts are model-specific; even small differences in burner components, electrical connectors, or mounting hardware can affect fit and safe operation. Using the exact model number and diagram callouts helps ensure you get the correct Hotpoint replacement part the first time.

On the Hotpoint RGAS300DM1WW gas range, the oven igniter is mounted inside the oven cavity at the bake burner; it sits near the burner where it can glow and light the gas. Access typically involves removing the oven bottom panel to reach the burner and igniter area (see the RGAS300DM1WW owner's manual).

What you will see when you find it

The oven igniter is a small, rectangular glow-bar style part positioned next to the bake burner so it can ignite the gas.

• It is not on the cooktop; it is in the oven section
• It is located along the bake burner path under the oven bottom
• It glows bright orange when the oven is calling for heat
• If it is weak, the oven may take a long time to light or may not light

Quick symptoms that point to an igniter issue

If your oven is not heating, these checks help separate an igniter problem from a gas supply or control issue.

Symptom	Most likely cause	What to check next
No heat, no glow from igniter	No power to igniter or failed igniter	Verify power, wiring, and igniter condition
Igniter glows but no flame	Weak igniter or gas valve not opening	Igniter strength, gas shut-off position
Delayed ignition (late light)	Weak igniter	Replace igniter
Surface burners work but oven does not	Oven gas shut-off closed	Check regulator shut-off lever

Before you start (safety and access basics)

We recommend these steps before removing panels or handling wiring.

• Turn off power to the range at the breaker (the igniter is electrical)
• Shut off the gas supply valve if you will be moving the range
• Let the oven cool completely
• Remove oven racks for working room
• Follow the access steps and panel removal notes in the RGAS300DM1WW installation guide

Parts that are commonly involved

If the igniter is cracked, does not glow, or causes delayed ignition, replacement is the standard fix. For this model, the listed igniter is the igniter glowbar WB13X30972.

Why it matters

The igniter does two jobs: it heats up to ignite gas and it helps the oven safety valve open. A weak igniter can prevent the valve from opening fully, so the oven will not light or will light late.
