Oven Not Heating Properly? Gas & Electric Troubleshooting Guide

Close-up of a failed electric bake element with visible breaks.

Common Causes

  • Electric: Failed bake/broil element, faulty temperature sensor, bad relay/board.
  • Gas: Weak igniter, faulty safety valve, incorrect air-gas mix.
  • User/placement: Rack position, door seal leaks, wrong cookware.

Safe DIY Checks

Visual Element Check (Electric)

  • Look for blisters/breaks; element should glow evenly. (Power off first.)

Thermometer Verification

  • Place an oven thermometer; preheat to 350°F; check after 15–20 min (±15°F is typical).

Gas Igniter Observation

  • You may observe a glow through vents; if it glows but burner doesn’t light, likely igniter/valve issue. (No disassembly DIY.)

When Not to DIY

  • Gas leaks/smells, valve issues, live wiring, control board replacement.
  • Unit under warranty.

Costs (Typical Ranges)

  • Electric elements/sensors: $120–$320 installed.
  • Gas igniter/valve: $180–$420+.
  • Control board/relay: $280–$600+.

FAQs

  • Why uneven baking? Rack placement, preheat time, fan issues (convection).
  • Calibrate or repair? Minor offsets can be calibrated; large deltas suggest parts failure.
