An electric oven that will not heat usually comes down to lost power on the 240-volt circuit, a locked or delayed control, a failed bake element, a door that will not seal, or a temperature sensor that is bent or faulty. Work through the checks below in order before you order parts. Fall and holiday cooking put more load on the oven, so catching a weak element or cool cavity now is better than discovering it on Thanksgiving morning.

> **Safety first:** Shut off the range at the circuit breaker (or unplug it if it has a cord) before you touch elements, wiring, or the back panel. Let heating elements cool completely. Do not bypass thermal fuses, high-limit switches, or door locks. If you smell gas on a dual-fuel range, leave the home and call the gas utility.

This guide is for **electric** freestanding ranges and wall ovens. Gas ovens fail differently (often the igniter); see the note at the end.

## 1. Rule out Control Lock, Demo mode, and Delayed Start

Before assuming a part failed, clear settings that intentionally block heat:

1. Cancel any active cycle, then cancel **Delayed Start** / **Delay Bake** if the display shows a future start time.
2. Look for **Control Lock** or a padlock icon. On many Whirlpool and similar ranges, hold the lock key for about 3 seconds to unlock.
3. On a newly installed or floor-model range, check for **Demo mode**, which can run lights and the display without enabling the heating circuits. Your owner's manual shows how to exit it.

Whirlpool's electric-range product help lists exactly these three control issues before any hardware diagnosis.

## 2. Check the circuit breaker (and remember: half power is common)

Electric ranges and most wall ovens need a dedicated **240-volt** circuit, usually a double-pole breaker. If one pole trips or is only partly on:

- The clock, lights, and some controls may still work.
- Bake and broil may do nothing.

At the panel, find the range breaker(s). Move a tripped breaker fully to **Off**, then back to **On**. If it trips again immediately, stop and call an electrician. Also look for a burned or discolored receptacle on cord-connected ranges; that needs an electrician, not a DIY patch.

Internal wiring at the terminal block matters most after a new install. Miswired colors or loose hex nuts on the terminal posts can leave the unit partially powered. That is an installation check, not a casual DIY task if you are unsure.

## 3. Test Bake and Broil separately

A quick split tells you where to look:

| What works | Likely area |
| --- | --- |
| Neither Bake nor Broil | Power supply, control lock/demo, control board, or shared safety device |
| Broil works, Bake does not | Bake element, its wiring, or its relay on the control |
| Bake works, Broil does not | Broil element, wiring, or relay |
| Elements glow but food stays underdone | Calibration, sensor position, door seal, or weak element |

1. Clear the oven so you can see the floor and ceiling.
2. Start **Bake** at about 350°F (177°C). Within a few minutes, the bottom (bake) element on many models should begin to glow red as it cycles.
3. Cancel, wait a minute, then start **Broil** and watch the top element.

No glow on an exposed element is a strong clue. Hidden ("hidden bake") elements under the floor need a technician or meter testing; you will not see them from inside the cavity.

## 4. Inspect the bake and broil elements

With power **off** and the oven cool:

1. Look along each exposed element for blisters, cracks, holes, or dark burn spots.
2. Confirm the element is seated and the mounting screws or terminals look intact (no melted insulation).
3. If you are comfortable with a multimeter and your manual gives a procedure, you can check continuity with power disconnected. Skip this if you are not sure how to work safely around high-voltage terminals.

A visibly damaged element that never glows almost always needs replacement. Manufacturer guidance often prefers a licensed technician for the electrical swap; if you do it yourself, match the exact part for your model and restore all covers before restoring power.

## 5. Check the oven door seal and closing

Heat that escapes through a bad gasket looks like an oven that "won't get hot enough," even when the element works.

- Wipe the gasket and the mating frame so crumbs are not holding the door open.
- Confirm the gasket is continuous, not torn, and still soft enough to compress.
- Close the door on a strip of paper in several spots; if the paper slides out with almost no drag all the way around, the seal or hinges may need service.

Warped doors and failed hinges are less common than dirty or flattened gaskets, but they show up on heavily used holiday ranges.

## 6. Check the temperature sensor position

Most modern electric ovens use a thin metal **temperature sensor** (often near the upper rear of the cavity) instead of a capillary thermostat bulb. Whirlpool notes that the sensor should sit at about a **90° angle** and must not rest against the liner or sit too close to a heating element. A bent sensor can report the wrong temperature so the control cuts power early—or, with some fault codes, refuses to heat.

With the oven cool:

1. Find the probe.
2. Gently straighten it so it stands clear in the airflow, away from racks and foil.
3. Do not wrap foil around the sensor or cover it with a liner.

If the display shows a sensor-related code (for example, some Whirlpool wall ovens use **F3 E0** for an open or shorted sensor circuit), try a one-minute power reset at the breaker per the brand's instructions. If the code returns, the sensor, harness, or control needs diagnosis.

## 7. Verify the real temperature with an oven thermometer

The U.S. Department of Agriculture's Food Safety and Inspection Service recommends using an **appliance (oven) thermometer** to confirm the cavity is heating to the set point. Hang the thermometer from a center rack, set the oven to 325–350°F (163–177°C), wait until the oven signals that it is preheated, then read again after a few minutes because opening the door drops the air temperature briefly.

- If the thermometer never rises much above room temperature, go back to power, lock/demo, and element checks—or schedule service.
- If it consistently runs high or low by a fixed amount (for example, always 25°F / 14°C low), many models let you apply an offset in the control settings. Use the thermometer at several set points before you decide.
- USDA FSIS also notes that when cooking meat and poultry, the oven should be set at **325°F (163°C) or higher**; verify with a food thermometer that the food itself reaches a safe internal temperature.

An inexpensive oven thermometer is the fastest way to separate "broken" from "needs calibration" before holiday baking.

## When it is probably not a DIY fix

Stop and call a qualified technician if:

- The breaker trips repeatedly or you see burned wiring or a scorched terminal block.
- Neither element glows after lock/demo/delay and breaker checks, and you are not equipped to test relays and boards.
- Sensor or control error codes return after a power reset.
- The range is dual-fuel or gas and you smell gas (leave and call the utility).
- You need element, sensor, or control replacement and are not comfortable working with 240-volt circuits.

Guessing at control boards is expensive. A diagnosis with a written estimate is cheaper than a stack of unused parts.

## Gas ovens: different first checks

If your oven is **gas**, the most common no-heat cause is a weak or failed **igniter**, not a bake element. Do not bypass safety valves. Clean only as your manual allows, and leave gas valve and burner work to a technician. For electric-only symptoms, stay with the steps above.

## Step-by-step summary

Estimated time: 45m

Tools: Flashlight, Oven thermometer, Screwdriver (some models), Multimeter (optional, for advanced checks)

1. **Confirm the oven is not locked or delayed.** Cancel any Delayed Start, and turn off Control Lock (often by holding the lock button for about 3 seconds). Check that Demo mode is not enabled on new or display-model ranges.
2. **Check the circuit breaker.** Find the range breakers in the panel. If a double-pole breaker is tripped or only one pole is off, reset it fully off, then on. Clock and lights can still work when heating power is lost.
3. **Test Bake and Broil separately.** With the door closed, start Bake at about 350°F (177°C) and watch whether the bottom element glows. Cancel, then try Broil and watch the top element. Note which modes fail.
4. **Inspect the bake and broil elements.** With power off and elements cool, look for blisters, cracks, holes, or burn marks on exposed elements. A damaged element that does not glow during a cycle usually needs replacement.
5. **Check the oven door seal and door closing.** Confirm the door gasket is seated, not torn, and that the door closes firmly all the way around so heat stays in the cavity.
6. **Inspect the temperature sensor position.** Locate the thin metal probe (often upper rear). It should sit clear of the wall and racks, typically near a right angle. Reposition gently if it is bent against the liner or too close to an element.
7. **Verify real oven temperature with a thermometer.** Hang an oven thermometer on a center rack, preheat to 350°F (177°C), wait for the oven to signal ready, then read again after a few minutes. Use that offset for baking or schedule service if the oven never heats.

## Frequently asked questions

**Q: Why does my electric oven clock work but the oven will not heat?**

A: Many electric ranges use a 240-volt circuit. The display and lights can run on part of that power while the bake and broil elements need the full circuit. Check for a tripped double-pole breaker or a half-tripped breaker first.

**Q: How do I know if the bake element is bad?**

A: Start a Bake cycle and look for a red glow on the bottom element within a few minutes. With power off and the oven cool, also inspect for blisters, cracks, or burn-through. No glow plus visible damage usually means a failed element.

**Q: Can I replace an electric oven heating element myself?**

A: Some homeowners replace a screw-in or plug-in element after shutting off power at the breaker. Manufacturer guidance often recommends a professional for electrical work. Follow your model's service instructions, and never work on live wiring.

**Q: What does Control Lock or Demo mode do to baking?**

A: Control Lock (child lock) blocks starting a cook cycle. Demo mode on some ranges runs the display and lights but will not heat. Clear both per your owner's manual before diagnosing parts.

**Q: My oven heats but food is undercooked. Is that the same problem?**

A: Not always. An oven that heats but runs cool or uneven may need calibration, a mispositioned temperature sensor, a weak element, or a door that leaks heat. Confirm with an oven thermometer before replacing parts.
