Kenmore 79077433902 gas range Parts

Your Kenmore gas range model number is printed on the appliance’s rating label. On many ranges, you’ll find it in the oven door jamb (open the oven door and check the frame), behind the storage drawer, or on the back panel near the vent area. Use the exact model number to match parts and manuals.

Where to look on a Kenmore range

Check these common label locations first:

• Oven door jamb (around the frame when the oven door is open)
• Behind the storage drawer or warmer drawer (pull the drawer out and look on the frame)
• Back of the range near the vent or rear panel
• Side panel area (less common, but possible)

If you already see 79077433902 on the label, that is the correct model number for this Kenmore gas range.

How to confirm you have the right number

Model labels can include several identifiers. Here is what to use:

Label item	What it’s used for	Example
Model number	Parts lookup, manuals, compatibility	79077433902
Serial number	Manufacturing info, service history	Varies
Gas type notes	Installation and conversion details	Natural gas or LP/Propane

For model-specific installation and identification details, use the 79077433902 installation guide.

Why it matters

Using the exact model number prevents ordering the wrong Kenmore parts (like an oven igniter, oven temperature sensor, or burner head) and helps ensure the correct clearances, gas supply setup, and anti-tip bracket requirements are followed.

Kenmore model 79077433902 is a Kenmore gas range built for Sears; the 790 model prefix is commonly associated with Frigidaire/Electrolux manufacturing for Kenmore ranges. For the most reliable confirmation, match the full model and serial information on the unit’s identification plate using the 79077433902 owner’s manual.

How to confirm the manufacturer from the model tag

The quickest way is to read the identification plate on the range and confirm the full model number and serial number.

• Open the storage drawer or warmer drawer.
• Look on the right side of the oven front frame for the serial plate.
• Verify the model number reads 79077433902.
• Record the serial number for your records.
• Use the model prefix (790) when cross-referencing parts and service information.

Where the model and serial number are located (79077433902)

The identification plate location is described in the documentation for this Kenmore range.

Item	Location on the range	Why you need it
Model number	Serial plate on right side of oven front frame (inside storage/warmer drawer area)	Confirms the exact version for parts lookup
Serial number	Same serial plate	Helps match production run details for service

Why it matters

Kenmore is a brand name used across multiple manufacturers. Confirming the 790 prefix and the exact 79077433902 model number helps us match the correct gas range parts (like an oven igniter, temperature sensor, or pressure regulator) and avoid ordering a similar-looking part that will not fit.

A Kenmore gas range like model 79077433902 typically lasts 15 years with normal household use. Regular cleaning, proper burner flame adjustment, and replacing wear items (like igniters and light bulbs) on time help you reach that lifespan.

Typical lifespan and what affects it

Most gas ranges reach their full service life when heat, gas flow, and airflow stay consistent.

• Heavy daily cooking can shorten lifespan
• Grease buildup around burners and in the oven can cause poor ignition and uneven heating
• Power surges and heat exposure can stress the electronic control
• Worn ignition parts can delay lighting and strain components
• Skipping routine cleaning can lead to flare-ups and overheating

What “normal wear” looks like on this range

Your 79077433902 manual notes that some items are considered expendable and wear out with normal use (for example, light bulbs). Use the 79077433902 owner's manual to match symptoms to maintenance and safe-use guidance.

Common wear items and symptoms:

What you notice	Likely area involved	What we usually check first
Oven takes longer to ignite or won’t heat	Oven ignition system	Igniter condition and wiring
Oven temperature swings	Temperature sensing/control	Sensor and calibration
Oven light out	Oven light	Bulb type and socket condition

Maintenance that helps you get the full 15 years

We recommend these habits for Kenmore gas ranges:

• Clean the range regularly to keep grease from building up (especially under burners)
• Keep burner ports clear and caps seated correctly after cleaning
• Use the vent hood and clean its filter so grease does not recirculate back onto the range
• If a surface burner goes out on LOW, adjust the low flame setting per the 79077433902 installation guide
• Replace failing ignition parts promptly, such as the tappan range oven burner igniter 316489403

Why it matters

A gas range usually fails early from preventable issues: delayed ignition, overheating from grease, and running burners with incorrect flame size. Keeping flames stable and surfaces clean reduces stress on the gas valve, igniters, and controls.

On Kenmore gas range model 79077433902, the oven typically won’t ignite when the hot-surface igniter is weak or failed, the oven gas valve is not opening, or the range is not getting electrical power. Normal ignition includes a 30 to 60 second delay before the burner lights. See the 79077433902 installation guide for how the ignition sequence is supposed to work.

Quick checks (most common causes)

• Wait a full 60 seconds after setting BAKE or BROIL; a short delay is normal.
• Confirm the range has power (clock/display on, no tripped breaker); the oven igniter needs electricity.
• Look for igniter glow through the oven bottom vents or by viewing the burner area; no glow usually points to an igniter or wiring issue.
• If it glows but never lights, the igniter can be too weak to open the gas valve.
• If you smell gas but no ignition, turn the oven OFF, ventilate, and do not keep retrying.

Parts that commonly fix “won’t ignite”

If your symptoms match, these are common replacements for this model:

Symptom	Likely part	What it does
No glow from igniter	Tappan range oven burner igniter 316489403	Heats up to ignite gas and help open the oven valve
Glow present, no flame	Range oven gas valve 316404901	Opens to release gas to the bake/broil burner
Oven heats erratically or wrong temp	Frigidaire range oven temperature sensor 316490000	Tells the control how hot the oven is

Safety notes that affect ignition

• Do not attempt to operate the electric-ignition oven during a power failure; reset controls to OFF if power goes out.
• Surface burners can be lit with a match during an outage, but the oven ignition system still requires power.

Why it matters

A weak igniter can glow yet fail to open the gas valve, which leads to repeated no-heat cycles and longer preheat times. Fixing the ignition system restores normal bake and broil performance and helps prevent gas odor from repeated attempts.
