Modern Maid PGO191 gas wall oven Parts

Yes. Gas wall ovens are a real product category, and your Modern Maid PGO191 is an example of a gas wall oven model. They are less common than electric wall ovens, but they’re used in many homes where a gas supply is available.

What “gas wall oven” means

A gas wall oven uses natural gas or LP (propane) for baking and typically uses household electricity for ignition, lights, and controls.

Common features you’ll see:

• Gas bake burner for heat
• Hot surface igniter or spark ignition system
• Gas safety valve/regulator components
• Thermostat or electronic oven control (varies by model)
• Electrical wiring for ignition and controls

What to check before choosing or replacing a gas wall oven

Gas wall ovens have a few fit and hookup requirements that matter as much as brand.

• Cutout size: wall ovens must match the cabinet opening
• Fuel type: natural gas vs LP conversion capability
• Electrical needs: most require a standard household circuit for ignition/controls
• Ventilation: follow local code and safe clearances
• Ignition type: older models often differ from Modern designs

Quick comparison: gas vs electric wall ovens

Feature	Gas wall oven	Electric wall oven
Heat source	Gas burner	Electric elements
Power needed	Usually for ignition/controls	Always for heating and controls
Commonness	Less common	Most common
Typical service items	Igniter, valve, burner parts	Bake/broil elements, relays

Why it matters

Knowing that PGO191 is a gas wall oven helps you troubleshoot correctly. For example, “no heat” on a gas oven often points to the igniter, gas valve, or burner circuit, not a bake element.

The most common problems we see with the Modern Maid PGO191 gas wall oven are no-heat or weak baking, uneven temperatures, ignition failures, and control or wiring-related faults. These issues usually trace back to the igniter, gas safety valve, thermostat/temperature sensor, or loose/burned wiring.

Most common symptoms (and what they usually mean)

• Oven will not heat: weak or failed hot-surface igniter, failed gas safety valve, or no power to controls
• Igniter glows but burner will not light: igniter is too weak to open the gas valve, or the valve is failing
• Slow preheat or low temperature: weak igniter, drifting thermostat, or calibration issue
• Uneven baking or hot spots: burner/airflow issues, heat loss at door gasket, or rack position problems
• No broil (if equipped): broil igniter/burner issue or selector/control problem
• Intermittent operation: loose wire connection, overheated connector, or failing control

Quick checks we recommend first

• Confirm the oven is getting power (clock/control lights on, breaker not tripped).
• Set to BAKE and watch for ignition: igniter should glow, then burner should light.
• Smell for gas only briefly during an ignition attempt; if you smell gas, stop and ventilate.
• Inspect the door seal for gaps, tears, or compression.
• Look for burned or loose wires at the igniter and valve connections.

Common causes and best next step

Symptom	Most likely cause	Best next step
No heat	Failed/weak igniter	Test igniter circuit and replace if weak
Glow, no flame	Weak igniter or bad gas valve	Amp-draw test; replace the failing part
Temperature off	Thermostat drift	Verify with oven thermometer; calibrate if possible
Cuts out	Loose/burned wiring	Repair connectors and damaged wiring

Why it matters

Gas ovens rely on the igniter to open the gas safety valve; a weak igniter is the most common reason a PGO191 will not light or heats poorly. Fixing the root cause restores safe ignition and stable temperatures.

For a Modern Maid gas wall oven like model PGO191, the model number is printed on the oven’s identification label (also called a rating plate). We use that exact model number to match the correct diagrams and replacement parts.

Where to look on a wall oven

Check these common spots first (use a flashlight):

• Along the oven frame behind the door, near the hinge area
• On the front frame (the lip around the oven opening)
• On the side trim or inner side panel visible when the door is open
• On the lower front frame near the broiler or lower access area (if your unit has one)
• On the back of the oven (usually only visible if the oven is pulled out)

What the label looks like

Most wall oven ID labels include several fields. Here is what to capture:

• Model (this is the key field)
• Serial (helps identify production run)
• Gas type (natural gas or LP/propane)
• Electrical rating (volts and amps)

Label field	What it’s used for	Should you record it?
Model	Correct parts lookup and diagrams	Yes
Serial	Version changes within a model	Yes
Gas type	Correct regulator/orifice setup	Yes
Electrical rating	Safe replacement of electrical parts	Helpful

Why it matters

Modern Maid ovens can have similar-looking variants; one character difference in the model number can change the correct igniter, thermostat, valve, or door parts. Using the exact label information prevents ordering the wrong part and delays in repair.

If the label is missing or unreadable

Use these practical options:

• Look for a second label on the back panel if the front label is damaged
• Check for a stamped plate on the frame near the storage/broiler area
• Search your paperwork for the installation receipt or service invoice
• Use our guide: [how to find your appliance model number (and what it means for parts)]
