How do I know if my igniter is bad on my gas stove?
On the Kenmore 79075721991 gas range, a bad igniter usually shows up as a burner that will not light (or takes a long time to light) even though you hear clicking. If the igniter has no electrical continuity, it is defective and needs replacement.
- Burner clicks but never lights, or lights only after a long delay
- Clicking continues even after the knob is turned past LITE (no flame established)
- Burner lights unevenly or goes out when you move from LITE to a lower setting
- You smell gas briefly because ignition is delayed (turn the knob OFF and ventilate)
- Other burners click at the same time, but only the selected burner should ignite
Before testing parts, confirm the basics described in the 79075721991 owners manual.
- Make sure the knob is turned to LITE to start ignition, then adjusted to a cooking flame
- Visually confirm the burner actually lights (do not rely on sound alone)
- Clean clogged burner holes; the manual notes the burner holes must be kept clean for proper ignition
- If the burner lights but goes out on LOW, the installation guide describes adjusting the LOW flame setting
A continuity test is the most direct way to confirm an igniter is bad.
- Unplug the range (or switch off the breaker)
- Access the igniter wiring connection
- Use a multimeter on continuity/ohms and test across the igniter leads
- No continuity means the igniter is defective
If you need the replacement part for ignition problems, use the model-matched frigidaire range oven burner igniter 5303935066.
| What you see | Most likely cause | What to do next |
|---|---|---|
| Clicking, no flame | Dirty/clogged burner holes or weak igniter | Clean burner, then continuity test |
| Flame lights only on LITE, goes out on LOW | LOW flame setting too low | Adjust LOW setting per 79075721991 installation guide |
| No clicking at all | Power supply issue or switch/wiring problem | Check outlet/breaker, then inspect wiring |
Delayed ignition can allow unburned gas to build up briefly, which is why we recommend turning the knob OFF if the burner does not light promptly and addressing cleaning or igniter testing right away.

How long should a Kenmore gas stove last?
A Kenmore gas range like model 79075721991 typically lasts 15 years with normal household use. Regular cleaning to prevent grease buildup and addressing ignition or heating issues early helps you get the full service life from the oven and burners.
Most gas ranges reach their expected lifespan when these conditions are consistent:
- Normal residential cooking (not heavy commercial-style use)
- Burners and oven kept free of grease and spillovers
- Proper gas supply and stable electrical power to the controls
- Prompt repair of ignition, temperature, or valve problems
- Safe cleaning practices that avoid damaging finishes and controls
Your 79075721991 manual emphasizes routine cleaning and grease control. Use these habits to reduce wear and prevent flare-ups:
- Clean the range regularly so grease does not accumulate on surfaces and under burner areas
- Wipe spillovers and heavy soiling as soon as the range is cool
- Use hot, soapy water for general cleaning; avoid abrasive cleaners that scratch
- When cleaning the control panel, keep water out of the controls (use a well-wrung cloth)
- Follow the self-clean instructions and remove items the manual says to remove first
For model-specific cleaning and care details, follow the 79075721991 owner's manual.
| Symptom | Common cause | What to check first |
|---|---|---|
| Oven will not heat | Weak igniter | Glow strength and ignition timing; consider frigidaire range oven burner igniter 5303935066 |
| Oven temperature swings | Sensor/probe issue | Inspect and test the temperature probe 5304497424 |
| Gas odor or poor flame | Gas supply/regulation issue | Shut off gas and inspect regulator and connections; consider range pressure regulator 5304521339 |
A gas range can run for many years, but grease buildup, moisture in controls, and ignored ignition problems increase stress on key parts (igniter, gas valve, temperature sensing). Preventive cleaning and early fixes protect performance and safety.

How to change Kenmore spark electrode igniter?
To change a spark electrode igniter on your Kenmore gas range model 79075721991, we disconnect power, remove the burner cap and head, swap the electrode and wire connection, then reassemble and test ignition. Handle the electrode carefully so it is not cracked or misaligned.
- Turn off power at the breaker (spark ignition is electric).
- Shut off the gas supply valve before disassembly.
- Let grates and burner parts cool completely.
- Avoid pulling on the wire; grip the connector instead.
- Do not overtighten small screws into the burner base.
- Remove the grate, then lift off the burner cap.
- Remove the burner head (some lift off; others are held by screws depending on burner style).
- Note the electrode position relative to the burner ports; it must sit in the same spot for reliable sparking.
- Disconnect the electrode wire connector.
- Remove the mounting screw and lift out the old electrode.
- Install the new electrode, secure it with the screw, and reconnect the wire.
- Reinstall the burner head and cap; make sure the cap sits flat.
- Restore gas and power; turn the knob to LITE and confirm the burner lights.
- Burner cap is seated correctly and dry.
- Electrode tip is not cracked and is close to the burner (not bent away).
- Burner ports are not clogged.
- All ignitors clicking is normal on this model; only the selected burner should ignite.
| Symptom | Most common cause | What we do next |
|---|---|---|
| No clicking at any burner | No power to range | Check breaker, outlet, wiring |
| Clicking but no spark at that burner | Bad electrode or loose wire | Reseat connector, replace electrode |
| Spark present but burner will not light | Gas flow or clogged ports | Clean ports, verify gas supply |
A properly positioned electrode creates a consistent spark at the burner. If the electrode is damaged or the cap is mis-seated, the burner may click continuously, light late, or not light at all.

How to take the top off a Kenmore gas range?
On the Kenmore 79075721991 gas range, the cooktop is not removable, so we do not take the top off like some other ranges. For most access and cleaning, we remove the grates and burner caps; for deeper service, we follow the disassembly access points shown in the installation guide.
- Lift off the surface grates.
- Lift off the burner caps.
- Wipe up spills around the burner heads and electrode area.
- Reinstall burner caps so they sit flat and centered.
- Set grates back in place and confirm they are stable.
If you are trying to reach wiring, switches, or gas components, we use service access panels rather than removing the cooktop.
Common service access points include:
- Rear access panel (controls, wiring harness connections)
- Storage drawer or warmer drawer removal for lower access
- Kick panel area (varies by configuration)
When reinstalling a warmer drawer, align the glides and push the drawer in until the levers “click” (about 2 inches), then pull it back open to seat the bearing glides.
| Goal | Remove first | Next step |
|---|---|---|
| Clean cooktop surface | Grates, burner caps | Clean and dry, then reinstall |
| Access lower components | Storage/warmer drawer | Use lower access area |
| Convert gas type (LP/Natural) | Grates, burner caps | Follow regulator and orifice steps |
Trying to force the cooktop up on model 79075721991 can bend panels, damage burner parts, or pinch wiring. Using the correct access method protects the burner system, igniters, and gas connections.

Where to find Kenmore gas range model number?
On the Kenmore gas range model 79075721991, the model and serial number are printed on an identification plate. You will typically find that plate either in the storage compartment on the right side of the oven front frame (many sealed-burner models) or under the lift-up cooktop (other gas models). See the 79075721991 owner's manual for the exact location notes.
- Storage drawer area: Pull out the storage drawer and look on the right side of the oven front frame.
- Under the cooktop: If your cooktop lifts, look under the lift-up cooktop for the identification plate.
- Warmer drawer models: Remove the warmer drawer to access areas behind it (the installation instructions describe drawer removal steps).
- Broiler drawer models: Fully open the broiler drawer and check around the front frame and lower cavity.
- Door frame area: Check the oven front frame near the door opening if you do not see it in the drawer area.
| Label item | What it looks like | Example format |
|---|---|---|
| Model number | Starts with the Kenmore prefix | 790.XXXXXXX |
| Serial number | Letters and numbers | Varies |
| Identification plate | Printed sticker or metal plate | Fixed to frame/cooktop area |
We use the exact model number to match the correct Kenmore parts list, wiring layout, and gas range components (like the oven igniter, pressure regulator, and oven light parts) so you get the right fit the first time.
