Whirlpool WFG550S0HB2 gas range Parts

To identify your Whirlpool stove model, we look for the model/serial tag on the range and match the model number exactly (for example, WFG550S0HB2). That exact model number is what we use to pull the correct Whirlpool gas range parts and diagrams.

Check these common locations on a Whirlpool gas range like model WFG550S0HB2:

• Oven door frame: open the oven door and look around the frame
• Storage or broiler drawer area: pull the drawer out and look on the frame or side panel
• Behind the control panel: sometimes visible from the back or underside of the console area
• Back of the range: a label on the rear panel
• Metal “dog tag”: a small swiveling tag near the back or side on some models

The model number is usually a mix of letters and numbers. Make sure you copy it exactly, including any trailing digits.

• Use the model number to find parts
• Keep the serial number for manufacturing date and service history
• Don’t use marketing names like “5-burner” or “self-clean” to order parts

Whirlpool ranges often share similar styling across multiple models, but internal components can differ. Using the exact model number helps us match the right igniter, oven sensor, control, or door hardware the first time.

Once you confirm the model number, these are examples of parts we commonly match by model:

• Range oven igniter WP9758079 (no bake or delayed ignition symptoms)
• Oven sensor W10833885 (temperature issues)
• Electronic control (black) W11258611 (display or keypad problems)

To reset a Whirlpool gas oven like model WFG550S0HB2, we typically clear the control by canceling the current cycle and power-cycling the range. This restores normal operation after a glitch, a stuck key, or an unresponsive display.

• Press CANCEL/OFF once to stop any bake or broil cycle.
• Wait 30 seconds.
• If the control is still acting up, turn off power to the range at the breaker (or unplug it) for 1 full minute.
• Restore power and set the clock if prompted.
• Test BAKE at 350°F for a few minutes to confirm the oven responds.

These checks help separate a control reset issue from an ignition or temperature-sensing problem:

• Confirm the range has power (clock/display on, surface burners spark).
• Make sure the oven is not in Control Lock (if your panel has that feature).
• If the oven clicks but will not light, inspect the igniter circuit; a weak igniter is a common cause.
• If the oven heats but temperatures are erratic, the sensor circuit is the first place we check.

If troubleshooting points to a failed component, these are common replacements for this model:

• Range oven igniter WP9758079
• Range oven burner igniter WPW10333842
• Oven sensor W10833885

A proper reset clears temporary control faults, but repeated failures usually indicate an underlying issue such as a failing igniter, a sensor problem, or a wiring connection that is overheating and opening under load.

On a Whirlpool gas range like model WFG550S0HB2, the F5 code during Self-Clean indicates the control is detecting a fault in the oven’s safety sensing circuit. On many Whirlpool ranges, that fault is tied to the door lock or door switch feedback used to confirm safe operation.

• Press Cancel/Off and let the oven cool completely.
• If the door is locked, wait for it to unlock on its own; do not force it.
• Turn power off at the breaker for 1 minute, then restore power.
• Check that the door closes fully and nothing is obstructing the latch area.
• Try a normal Bake cycle; if Bake works but Self-Clean triggers F5, avoid Self-Clean until repaired.

F5 is most often triggered by one of these issues:

• Door lock mechanism sticking after high heat
• Door switch not changing state when the door closes
• Loose or heat-damaged wiring at the latch or control
• Failed electronic control input circuit

If the range is not reliably detecting door position, the door switch is a common checkpoint; for this model, see the door switch WP9757262. If symptoms include repeated F5 with other control glitches, the control board can be involved; see the electronic control (black) W11258611.

Self-Clean uses very high temperatures; the range must confirm safe door and lock status. When the control cannot confirm that status, it stops operation and displays an error to prevent unsafe conditions.

For a Whirlpool WFG550S0HB2 gas range, we recommend a 3/4-inch rigid gas supply pipe to the range location; long runs with smaller pipe can restrict flow. For LP (propane), 1/2-inch minimum piping or tubing is commonly used.

Use these sizes as a practical baseline for most residential installations; your final sizing should match local code and the length of the run.

• Natural gas: 3/4-inch rigid pipe to the range location
• LP (propane): 1/2-inch minimum piping or tubing is typical
• Longer runs: upsizing helps prevent low burner flame and slow oven preheat
• Connector: use an approved flexible gas connector sized for ranges (don’t reuse a kinked connector)
• Shutoff valve: install an accessible manual shutoff valve near the appliance

If the supply line is undersized, the cooktop may show weak flames and the oven may take longer to ignite or heat because the gas valve and burner cannot get steady flow at the required pressure.

• Check for weak flames on multiple burners
• Confirm the shutoff valve is fully open
• Make sure the flexible connector is not kinked or crushed
• If the oven struggles to light, inspect the igniter system (a weak igniter can mimic a supply issue); see range oven igniter WP9758079
• For ignition problems at the bake burner, also consider range oven burner igniter WPW10333842

On a Whirlpool WFG550S0HB2 gas range, a cooktop igniter usually stops working because the burner cap is mis-seated, the igniter electrode is dirty or cracked, moisture is present, or the ignition circuit (switch, wiring, or spark module) is failing. Start with cleaning and alignment, then test the ignition circuit.

• Confirm the burner cap sits flat and centered on the burner base.
• Clean and dry the igniter tip and the metal burner ports (spills and grease block spark and gas flow).
• If it clicks but will not light, try lighting another burner; if others light normally, the issue is localized.
• If none of the burners click/spark, suspect the ignition power path (switch harness, wiring, or spark module).
• If it clicks continuously, a stuck switch or moisture around a knob/valve area is common.

If cleaning and drying do not restore spark, these model-compatible parts are common next steps:

• Valve-gas,ae W11449506 (a faulty valve or switch assembly can prevent proper ignition)
• Manifold asm W11347745 (manifold and valve mounting area; damage or wear can affect switching)

A weak or missing spark can cause delayed ignition, uneven flames, or repeated clicking. Fixing alignment, cleanliness, and ignition components helps the burner light quickly and keeps cooking performance consistent.
