Kenmore 79074503990 dual-fuel range Parts

For your Kenmore dual-fuel range, the model number is printed on the appliance’s rating label; on ranges like the 79074503990, it’s most often found around the oven door frame or storage drawer area. Use the exact model number to match diagrams and order correct parts.

Where to look on a Kenmore range

Check these common label locations (look for a sticker or metal plate):

• Left or right side of the oven door frame (open the oven door)
• Drawer frame behind the storage or warming drawer (pull the drawer out)
• Lower front frame near the broiler or kick plate area
• Back panel of the range (if safely accessible)
• Under the cooktop edge on some models

What you should write down

The label usually includes more than one identifier. Record all of these so we can match parts accurately:

• Model number (example format: 790.7450xxxx)
• Serial number
• Electrical rating (volts/amps) and gas type (important on dual-fuel ranges)

Quick ID guide

Label item	What it’s used for
Model number	Selecting correct parts diagrams and assemblies
Serial number	Identifying production run details
Electrical rating	Verifying power supply requirements

Why it matters

Kenmore model numbers can look similar across different ranges; one digit difference can change the correct bake element, oven rack, igniter, or control parts. Using the rating label prevents ordering the wrong component.

The most common problems we see on Kenmore dual-fuel ranges like model 79074503990 are uneven baking, an oven that will not heat, gas burners that click but do not ignite, and temperature swings. These issues usually trace to heating, ignition, airflow, or control components.

Common symptoms and likely causes

• Oven not heating or slow to preheat: failed bake element, temperature sensor issue, control/relay problem
• Uneven baking: weak bake element, convection fan not running, rack position or airflow blockage
• Gas burner won’t ignite (clicking): dirty burner cap/ports, igniter or switch issue, moisture after cleaning
• Oven temperature inaccurate: sensor probe drifting, calibration needed, door not sealing
• Self-clean door won’t unlock: latch motor sticking or switch alignment

Parts that often solve these problems

If your symptom matches, these model-compatible parts are commonly involved:

• Bake element 318255201 (electric oven heat)
• Sensor probe 316217002 (oven temperature feedback)
• Cooktop burner igniter 318148700 (spark at the burner)
• Cooktop burner igniter switch 318037700 (triggers sparking)
• Latch motor 318095956 (self-clean door lock)

Quick troubleshooting checks (before replacing parts)

• Confirm the range has correct power (dual-fuel still needs full electric supply for the oven)
• Inspect burner caps for proper seating and clean clogged ports
• Look for visible damage on the bake element (blisters, cracks, holes)
• If you smell gas without ignition, stop and ventilate; do not keep clicking the igniter

Why it matters

Matching the symptom to the right system (gas ignition vs. electric oven heat vs. door lock) prevents unnecessary part swaps and gets your 79074503990 back to safe, consistent cooking faster.

For diagnostic steps, error indications (if applicable), and safe access panels, use the owner's manual.

The average lifespan of a Kenmore dual-fuel range like model 79074503990 is 15 years with normal household use and basic maintenance (cleaning burners, keeping the oven vent clear, and avoiding repeated self-clean overheating).

What affects lifespan most

These factors have the biggest impact on how long a dual-fuel range lasts:

• Heat stress from frequent high-temp baking, broiling, or self-clean cycles
• Power quality (surges can damage the oven control and relays)
• Gas burner cleanliness (clogged ports cause delayed ignition and extra wear)
• Door seal condition (heat leaks make components run hotter and longer)
• Cooling airflow (blocked vents can overheat electronics)

Typical lifespan by major system

System	Typical service life
Gas cooktop burners and caps	10 to 20 years
Oven heating elements	8 to 15 years
Electronic controls and relays	8 to 15 years
Convection fan motor	10 to 15 years

Maintenance that extends life

• Keep burner caps seated correctly and clean ports regularly
• Avoid running back-to-back self-clean cycles
• Replace worn door springs or hinges if the door won’t close tightly
• If baking is uneven, test temperature accuracy and address it early

Why it matters

Dual-fuel ranges combine gas ignition parts with electric oven heating and controls; keeping heat and airflow under control reduces failures in high-cost components.

For model-specific care and cleaning guidance, follow the owner's manual.
