Common Oven, Range and Cooktop Problems We Repair

These are the most common issues we see with electric and gas ovens, ranges and cooktops in homes, rentals and condos. Each section gives clear DIY checks and explains what a professional technician looks at in more detail.

1. Oven Not Heating

If the oven does not heat at all or stays cold on bake or broil, there is usually a problem in the heating circuit: elements, gas ignition system, temperature sensor, or control board.

Most Likely Causes

• Broken bake or broil heating element (electric)
• Failed igniter or gas valve issue (gas)
• Faulty oven temperature sensor
• Blown thermal fuse or high limit
• Defective control board or relay

DIY Checks (Basic and Safe)

• Confirm that the clock is set and oven is not in demo or Sabbath mode.
• Check that the door is closing fully and there are no error messages on the display.
• For electric ovens, look at the elements - if you see visible breaks or burn marks, the element is likely failed.
• For gas ovens, listen for the sound of the igniter clicking or glowing and the burner lighting.
• Verify that the breaker is not tripped and the range has power to both legs (for 240V electric ranges).

Internal testing of elements, igniters and fuses requires the oven to be disconnected from power and often pulled out from the wall. If you are not comfortable with this, it is safer to call a technician.

2. Oven Temperature Is Off or Inconsistent

When food is undercooked, overcooked or unevenly baked, even though the oven runs, it usually means the temperature control is not accurate or the heat is not distributed correctly.

Possible Causes

• Oven temperature sensor out of range
• Control board not reading the sensor correctly
• One of the elements weak or not cycling correctly
• Door gasket leaking heat
• Incorrect rack position or blocked airflow inside the cavity

DIY Checks

• Use an oven thermometer to compare set temperature with actual temperature inside the oven.
• Test several temperatures (for example, 350°F and 400°F) and note if the oven runs consistently too low or too high.
• Inspect the door gasket for gaps, tears or areas that do not seal well.
• Avoid covering racks or the bottom of the oven with foil, which can block airflow and cause hot spots.
• Check the user manual for a temperature calibration option in the settings.

If the oven is more than a small amount out of range or fluctuates a lot, the sensor or control usually needs professional testing and possible replacement.

3. Stove or Cooktop Burners Not Working

Burners that do not light, only work on some settings, or keep going out can be caused by problems in the surface burner system, either electric elements or gas burner parts.

For Electric Cooktops

• Failed surface element
• Bad infinite switch or control for that burner
• Loose connection in the harness or terminal block
• Burnt contact where the element plugs in (coil type)

For Gas Cooktops

• Clogged burner ports or caps not seated correctly
• Weak or no spark at the igniter
• Moisture around the igniter after a spill
• Gas not reaching the burner due to valve or manifold issues

DIY Checks

• Try switching two similar electric elements (if plug-in coil type) to see if the problem follows the element.
• Inspect the element and its contacts for burn marks.
• For gas, clean the burner cap and burner head, making sure all ports are open and dry.
• Check that the cap is sitting flat in the correct position.
• After spills, let the top dry completely and then test again.

If there is no spark at one or more burners, or multiple burners fail at once, the ignition system or wiring usually needs professional attention.

4. Sparks or Arcing From Oven or Cooktop

Visible sparks or arcing are serious symptoms. They can be caused by damaged wiring, shorted components, broken enamel, or wet igniters. These issues should be inspected and corrected quickly for safety.

Possible Sources

• Electric element touching the cavity or broken insulator
• Damaged or burnt wiring inside the oven or behind the control panel
• Moisture around gas igniters causing continuous sparking
• Food or grease buildup causing arcing near the element
• Failed control or spark module

What You Can Do Safely

• If you see active sparking, turn the oven or cooktop off immediately.
• Switch off the breaker for the range to cut electrical power.
• For gas units with constant clicking after a spill, allow everything to dry completely and clean around the igniters.
• Do not keep using the appliance until a technician inspects it.

Repeated sparking or arcing can damage wiring and controls and is a fire and shock risk. This is not a situation to ignore.

5. Oven or Range Shows Error Codes

Modern ovens and ranges often display error codes when a sensor, keypad, control, or safety circuit detects a fault. These codes help guide the diagnosis but need to be interpreted correctly.

Typical Error Code Causes

• Oven temperature sensor out of range
• Stuck or shorted keypad button
• Communication error between boards
• Locked door mechanism not responding
• Over-temperature or safety trip

DIY Steps Before Calling

• Note the exact error code shown on the display (for example, F1, F3, F9, etc.).
• Try turning power off at the breaker for 5 minutes, then restore power to see if the code returns.
• Check that the door is closing correctly and that there are no obstructions.
• If the code appears only during self-clean, stop using self-clean until the fault is inspected.
• Have the model number and error code ready for the technician. This speeds up diagnosis and parts preparation.

Many error codes point to specific components, but the part should still be tested rather than replaced blindly.

⚠ Ovens and ranges involve high voltage and, for gas models, open flame and gas supply. Always turn off power at the breaker, and close the gas valve for gas ranges, before removing panels. If you smell gas, do not attempt repairs yourself - ventilate the area and contact a professional immediately.

Oven and Stove Maintenance Tips To Prevent Problems

Simple maintenance can extend the life of your oven and cooktop and reduce breakdowns, especially in busy family kitchens and rental units.

• Clean spills early: Wipe up heavy spills once the oven cools. Baked-on food can cause smoke, smells and hot spots.
• Avoid covering vents with foil: Foil on the bottom of the oven or blocking vents can disturb airflow and damage components.
• Keep burner parts clean: For gas tops, keep burner caps, heads and ports free from grease and food.
• Use self-clean with care: Self-clean runs at very high temperature and can stress parts. Do not use it just before hosting or holidays.
• Check door gasket: Replace torn or crushed gaskets so the oven keeps heat inside and maintains stable temperature.
• Do not slam the door: Repeated hard closing can damage hinges, glass and door switches.
• Test burners regularly: Light all burners and the oven occasionally to catch ignition problems early.

Oven and range inspection can also be included as part of our annual appliance maintenance and protection plans.
