Oven not turning on

Short answer

When an oven won't turn on at all, the cause is often power or a control setting rather than a failed heating part: a tripped breaker, a control lock, a delay start, or a demo or Sabbath mode left on.

Soon An oven that won't start is usually an inconvenience, but a breaker that trips again, a burning smell or any smell of gas on a gas range means leaving it off.

Quick answer

What this symptom usually means

When an oven won't turn on at all, the cause is often power or a control setting rather than a failed heating part: a tripped breaker, a control lock, a delay start, or a demo or Sabbath mode left on. Whirlpool's list for an electric range where nothing works starts with a blown fuse or tripped breaker, then a recent power outage, which can leave an F9 or F9 E0 code from a voltage problem, then the control lock, a delayed start and demo or showroom mode. It adds that on some models Energy Save mode blanks the display when the oven isn't in use. GE's list for an oven that won't come on includes controls not set properly, knobs put back in the wrong place after cleaning, a breaker off or a fuse blown, a plug not fully in, an electronic control needing a reset, a self-clean latch not moved fully to unlocked, and Sabbath mode.

It helps to separate a dead display from a display that works while the oven won't heat. A dead display points to the supply, the control, or on some models a thermal fuse. A working display with no heat points to a setting, an element, the igniter on a gas oven, or a relay; see oven not heating for that. Most electric ranges and wall ovens run on 240 V from a double breaker, and GE says to check that neither side has tripped. A gas range still needs electricity for its control and oven igniter, so a tripped breaker or unplugged cord stops it too. On a newly installed or moved range, Whirlpool lists loose strain relief, mismatched wire colours and loose terminal nuts at the connection as causes; that connection is for the installer or a technician, not the homeowner.

Stop and call if: The breaker trips again after one reset; A burning or electrical smell, or scorch marks at the back of the range; Sparks or arcing from an element; On a gas range, any smell of gas (see smell of gas).
Safe to try first

Checks you can do yourself

  1. Check the breaker or fusesAn electric range or wall oven is usually on a double breaker. GE says to check that neither breaker has tripped, and to check fuses in older panels. Switch a tripped breaker fully off, then back on. If it trips again, leave it off and book.
  2. Plug fully inOn a freestanding range, GE says to make sure the plug is fully in the outlet. Only check this if you can see or reach it without dragging the range; on a gas range, don't pull it out, because the gas connector is behind it.
  3. Look for a lock or mode messageWhirlpool lists control lock, delay start and demo or showroom mode as reasons an oven won't respond, and GE adds Sabbath mode. A padlock icon or LOC usually clears by holding a key; on the Whirlpool ranges we checked it's Start/Enter for five seconds. Demo mode shows messages such as Showroom Mode or Try the Product and is switched off in settings.
  4. Wake a blank displayOn some Whirlpool models Energy Save mode blanks the display when the oven isn't in use; Whirlpool says holding Settings/Clock for three seconds brings it back.
  5. Reset after a power cutWhirlpool's reset is to switch off the range breaker for one minute, turn it back on and watch the display for a minute. If F9 or F9 E0 keeps coming back, Whirlpool says the outlet may be miswired and an electrician should check the supply before anything else.
  6. Knobs and the self-clean latchIf knobs were removed for cleaning, GE says to check each went back on its own shaft in the right position. On older ranges with a manual self-clean latch, GE says it must be slid all the way to the left, to unlocked.
  7. Look at the bake elementWith the oven off and cold, look at the lower element if it's exposed. GE says an element with cracks or breaks needs replacing. Don't touch it with the power on.

Nothing above involves gas, wiring, refrigerant or removing panels.

Most likely causes

What you notice, and what it can point to

Listed in no particular order. They help you describe the problem; only an inspection confirms the fault.

You notice

Display blank, nothing works

Could point to: Tripped breaker, blown fuse or plug not fully in (GE)

Next step: Reset the breaker once; book if it stays dead or trips again

You notice

LOC, Lock or a padlock icon

Could point to: Control lock on (Whirlpool)

Next step: Hold the unlock key for the time your manual gives

You notice

Showroom Mode or Try the Product on the display

Could point to: Demo mode enabled (Whirlpool)

Next step: Switch it off in settings as the manual shows

You notice

F9 or F9 E0 after a power cut

Could point to: Control detected incorrect voltage (Whirlpool)

Next step: Breaker off for one minute; if it returns, electrician first

You notice

Display works, oven won't start a bake

Could point to: Delay start, Sabbath mode or swapped knobs (Whirlpool, GE)

Next step: Cancel, reselect Bake and check the knobs

You notice

Oven dead after a self-clean

Could point to: Oven still locked and cooling, or a safety device opened

Next step: Wait for it to cool; see the self-clean guide; book if still dead

How it differs by design

  • Freestanding electric range: plugs into a 240 V outlet behind the range on a double breaker. GE says to check both breakers and that the plug is fully in.
  • Gas range: plugs into an ordinary 120 V outlet for the clock, control and oven igniter. No power means no oven, even with gas available.
  • Wall oven: usually hard-wired to a junction box with no plug. The breaker is the only reset, and disconnecting it is technician work.
  • Touch controls: can be locked, in demo or Sabbath mode, or blanked by an energy-saving setting. Whirlpool's lock guidance for its ranges is to hold Start/Enter for five seconds; other models use a different key or time.
  • Knob controls: GE says knobs removed for cleaning must go back on the right shafts in the right position, or the oven may not come on.
  • Older homes: some older panels still use fuses. GE's checklist includes checking for a blown fuse.
On the visit

What our technician checks

These need panels off, live electrical tests or a licensed trade, so they are left to the technician:

  • Pulling the range out and working at the terminal block, cord or outlet
  • Testing voltage at the outlet, breaker or junction box
  • Removing the back or control panel to test the control, fuses or relays
  • Disconnecting or reconnecting a hard-wired wall oven
  • Any gas-side work: igniter, valve, burner or connector

Common parts involved

Repairs a technician may recommend

After inspection, not from the symptom alone.

Repair

Control board or touch panel

When power reaches the oven but the display stays dead or won't respond to any key.

Repair

Terminal block or power cord

When a range was recently installed or moved and has no power or only partial power. Whirlpool lists loose strain relief, mismatched wires and loose nuts at the connection. Scorching there is repaired before anything else.

Repair

Thermal fuse or high-limit

On models that have one, when it has opened after overheating, for example after a self-clean. The cause of the overheating is checked too. See oven self-clean problems.

Repair

Bake or broil element

When the display works but the oven won't heat and an element is broken or open. See oven not heating.

Repair

Door lock assembly

When the control refuses to start any cooking mode because it believes the door is still locked.

Repair

Oven igniter or gas valve (gas ovens)

When a gas oven's display works but it never lights. We diagnose it; igniter and valve work is done by the certified gas contractor we work with.

Brand-specific

Brands we see with this problem

Codes, parts and access differ by brand; the brand pages cover where the model label is and what to expect.

Repair or replace

Cost, and whether to fix it

What the repair costs depends on the part, the labour and whether a second visit is needed for an ordered part; the written finding gives the total before any work. Our guides on what drives repair costs, oven repair costs and repair versus replacement explain how to weigh it.

When to book

Book when the display stays dead after a single breaker reset, when the breaker trips again, or when the display works but none of the lock, delay or mode checks gets the oven going. If Whirlpool's F9 code keeps returning, have an electrician check the outlet first, as Whirlpool advises. Tell us the brand and model, whether it's electric or gas, whether the cooktop or clock still works, and whether it happened after a power cut, a move or a self-clean. We diagnose gas appliances; burner, igniter, valve and gas-connection work is done by a certified gas contractor we work with. The visit is $89, waived if you go ahead with the repair, with a written finding before any work. See oven repair, stove and range repair or wall oven repair; we serve areas such as Stittsville, Orléans and Aylmer.

Questions

Oven not turning on: questions

Why won't my oven turn on but the stovetop works?

The range has power, so the problem is on the oven side: a setting such as delay start or Sabbath mode, the door lock, an element, or the control. Check for a lock or mode message first. If the display works but there's no heat, the oven-not-heating guide covers element checks.

How do I reset my oven after a power outage?

Whirlpool's advice is to switch off the range breaker for one minute, turn it back on and watch for an error code. If F9 or F9 E0 comes back, it says the outlet may be miswired and an electrician should check it.

Why does my oven say LOC?

It's the control lock. Whirlpool says it disables the keypad and locks the door to prevent unintended use. On the Whirlpool ranges we checked, holding Start/Enter for five seconds switches it off; check your manual for your model's key.

Does a gas oven need electricity?

Yes. Modern gas ranges use electricity for the control, clock and oven igniter, so a tripped breaker or an unplugged cord stops the oven even when gas is available.

My oven won't turn on after self-clean. Why?

It may still be locked and cooling, or the heat may have opened a safety device or finished off a weak part. See the self-clean problems guide for the steps. If the breaker trips, leave it off and book.
