Key Takeaways
- A Kenmore electric range with a failed bake element will show no visible glow at the oven bottom when a bake cycle is started — this is the fastest visual confirmation of element failure.
- On gas ranges, a cracked or worn oven igniter glows but cannot reach ignition temperature — the gas valve stays closed and the oven never lights, even though you see an orange glow.
- Error code F1-E0 on 790.xx Frigidaire-platform and 665.xx Whirlpool-platform ranges indicates a control board fault that requires professional evaluation.
- The oven temperature sensor (RTD) is the second most common cause of heating failure — a failed sensor causes the board to misread cavity temperature and halt heating.
- Running the self-clean cycle shortens control board lifespan on older Kenmore ranges — use it sparingly and never start a self-clean cycle on a hot oven.
The Bottom Line
Most Kenmore range heating failures are element or igniter faults — relatively straightforward repairs. Error codes F1-E0 and F2-E0 indicate control board or thermistor faults that require professional diagnosis. Do not use the range until heating faults are resolved.
Why Your Kenmore Range Is Not Heating
A Kenmore range not heating renders the oven completely unusable and makes cooktop use unreliable on electric models. Kenmore ranges are built on two primary platforms: 790.xx units are Frigidaire/Electrolux-built, and 665.xx units are Whirlpool-built. Both platforms use similar component layouts — a bake element (electric) or oven igniter (gas), an oven temperature sensor (RTD probe), and an electronic control board. Identifying the error code on the display panel is the fastest way to determine which component has failed before a technician arrives.
Quick Diagnosis Table
| Symptom | Error Code | Likely Cause | DIY Fix? |
|---|---|---|---|
| No glow from bake element | None or F1-E0 | Bake element failed (open circuit) | Element swap possible |
| Gas oven glows but no flame | None | Weak or cracked oven igniter | No — gas work, call service |
| Preheat stalls below set temp | Er ES | RTD sensor open or shorted | No — service required |
| Control lockout, display flashes | F1-E0 | Control board EEPROM fault | No — service required |
Cause 1: Failed Bake Element (Electric Models)
The bake element is the coiled metal rod at the bottom of the oven cavity. It eventually fails after years of thermal cycling — typically after 10–15 years of regular use, though heavy baking schedules shorten that lifespan. A failed element shows no visible glow when a bake cycle begins; a partially failed element may glow unevenly or show a burn hole or blister on the outer sheath. Multimeter continuity testing confirms whether the element has an open circuit. On 790.xx Frigidaire-platform models, the bake element is a straightforward replacement that requires disconnecting two wire terminals and removing two mounting screws. On 665.xx Whirlpool-platform models, the process is similar. Part numbers vary by model and are confirmed at searspartsdirect.com.
Cause 2: Weak or Cracked Oven Igniter (Gas Models)
Gas Kenmore ranges use a glow-bar igniter to open the gas valve and ignite the burner. The igniter must draw enough current (typically 3.2–3.6 amps) to heat the bimetal element in the gas valve and allow gas to flow. As igniters age, their electrical resistance increases and they draw less current — they glow orange but cannot reach the amperage threshold to open the valve. Gas never reaches the burner, so the oven never lights despite a visible glow. A cracked igniter shows the same symptom. Igniter replacement is a professional repair because it involves working adjacent to the gas supply inside the oven cavity.
Cause 3: RTD Oven Temperature Sensor Failure
The RTD (resistance temperature detector) probe extends through the rear wall of the oven cavity and reads the cavity temperature. The electronic control board uses this reading to cycle the bake element or gas valve on and off. When the RTD probe develops an open circuit or reads out of specification, the board receives incorrect temperature data and either halts heating entirely or allows the oven to overheat. Error code Er ES on Kenmore display models signals a sensor fault. The sensor is mounted with two screws inside the oven cavity and is one of the quicker repairs on most Kenmore range models.
