Electric ovens & cooktops

Both bake and broil elements not working, but display and light work

When both heating elements fail simultaneously while the display and light still work, the shared relay board or a shared power leg failure is more likely than two elements failing at the exact same time.

Symptoms

  • Neither bake nor broil produces any heat
  • Display, clock, and interior light all work normally
  • Fan (if convection) may still run
  • No error codes are shown despite the lack of heat

Likely causes

  • CommonLoss of one leg of 240V power while 120V circuits (display, light) still workOvens split power between a 120V circuit for lights/controls and 240V for heating elements; losing one leg kills heat but not the display.
  • CommonFailed relay board controlling both elementsA shared relay or board component that switches power to both elements can fail, cutting heat entirely while leaving low-voltage functions intact.
  • PossibleBlown thermal fuse cutting power to both heating circuitsA safety fuse tripped from a prior overheat can block both elements simultaneously.
  • Less commonLoose main power connection affecting only the high-voltage sideA partially loose main feed can selectively affect the 240V side while 120V functions continue.

What to do

  1. Check your breaker panel for a double-pole breaker where one side may have partially tripped, resetting it fully off then on.
  2. Confirm the oven's power cord and connection at the wall or junction box are secure.
  3. Unplug the oven at the breaker for a minute to reset the control board, then test bake and broil again.
  4. Do not attempt to test 240V connections yourself unless experienced with electrical work.
  5. Have an electrician verify both legs of the 240V circuit are supplying power correctly to the oven.
  6. Have an appliance technician check the thermal fuse and relay board if the electrical supply tests fine.
  7. This combination of symptoms (no heat, but display/light work) is a strong clue for a technician, so relay this detail when scheduling service.

When to call a pro

Have an electrician check the 240V supply and an appliance technician check the relay board and thermal fuse for this specific symptom combination.

Safety

Use caution

Do not test 240V wiring yourself; have an electrician check for a partial power loss before assuming both elements failed at once.
