Symptoms
- • Broil element remains completely cold when turned on.
- • Broil element heats intermittently or shuts off too soon.
- • Visible blisters, cracks, or burnt spots on the top heating element.
- • Gas smell but no flame when broil is selected (gas ovens).
- • Oven bakes perfectly fine, but the broil setting fails entirely.
- • Oven takes an unusually long time to preheat (as the broiler often assists).
Common causes
- • Burnt out or physically damaged broil heating element (electric).
- • Weak or failed broil igniter that cannot open the gas valve (gas).
- • Faulty oven control board with a burnt-out broil relay.
- • Blown thermal fuse or high-limit thermostat, often triggered by self-cleaning.
- • Damaged wiring or burnt terminal connections at the element.
- • Defective selector switch on older, dial-operated ovens.
Safety First — Read Before You Start
- •Always disconnect power at the breaker before inspecting or testing internal oven components. 240V electric ovens carry a lethal amount of current.
- •For gas ovens, shut off the gas supply valve before accessing the burner area. Never attempt to modify gas valves or supply lines yourself.
- •Heating elements and igniters are extremely fragile. Handle replacements with care and avoid touching the glow bar of a gas igniter with bare hands, as skin oils can cause premature failure.
- •If you smell gas continuously, do not attempt repairs. Evacuate the area, call your local gas provider (such as Puget Sound Energy, NW Natural, or Cascade Natural Gas), and contact a professional.
- •Never bypass a thermal fuse or high-limit switch. These are critical safety devices designed to prevent house fires.

Step-by-step instructions
Perform a Visual Inspection of the Element or Burner
Start by using a flashlight to inspect the top heating element inside your oven. If you have an electric model, look for signs of physical damage like bubbling, pitting, or a clean break in the coil. Arcing often leaves a charred or white mark. For gas models, inspect the burner tube and the igniter; look for soot buildup or a cracked igniter cage.
Tip: A visible break or blister on an electric element is a sure sign of failure. You can skip the meter test; it needs to be replaced. These usually range from $25 to $80.
⚠ Warning: Do not touch the element to check for heat. Keep your hand a safe distance away to feel for radiation.
Test the Electric Broil Element for Continuity
With the power cut at the breaker, remove the two 1/4-inch hex screws holding the element to the rear wall. Pull it forward carefully to access the terminals. Use needle-nose pliers to disconnect the wires. Set your multimeter to the continuity or lowest Ohms setting. Touch the probes to the terminals. A functional element should show between 15 and 40 ohms. If the meter reads infinite resistance (OL), the part is faulty.
Tip: Use a binder clip to hold the wires to the oven wall so they don't slide back into the insulation while you work.
⚠ Warning: Verify the power is off. 240V lines are dangerous.
Observe and Test the Gas Igniter (Gas Ovens Only)
Gas broilers use a glow-bar igniter to initiate the flame. Set the oven to Broil and watch the igniter for 30 to 60 seconds. It should glow bright. If it doesn't glow, it has no power or is dead. If it glows a dim orange but won't light the gas, it is likely weak. Gas safety valves need 3.2 to 3.6 amps to open; if the igniter cannot pull that current, the gas won't release. You can test continuity when cold, but an amp-clamp test is the most accurate way to confirm a weak igniter.
Tip: A weak igniter is the most frequent cause of gas broil failure. Swapping this part ($40-$90) usually fixes the issue.
⚠ Warning: Never attempt to light a gas broiler with a match. The safety valve is designed to prevent flow until specific electrical conditions are met.
Inspect the Wiring and Terminals
If the element or igniter tests fine, check the connections. Over time, high temperatures can corrode or loosen the spade connectors. In humid PNW environments—like coastal areas near Bellingham or Tacoma—damp air can accelerate terminal oxidation, leading to high resistance and burnt wires. If you find a damaged wire, trim the end back to clean copper and crimp on a new high-temp, nickel-plated terminal.
Tip: Standard hardware store terminals will fail in an oven. Use only high-temperature, uninsulated nickel terminals and specialized fiberglass-wrapped wire.
⚠ Warning: Ensure the connection is secure to prevent future arcing.
Check the Thermal Fuse or High-Limit Switch
Many ovens feature a thermal fuse or high-limit switch that cuts power during overheating, often triggered by a faulty cooling fan or a high-heat self-clean cycle. You will need to pull the oven out and remove the rear panel to find it. The fuse, often a white or ceramic component with two wires, should show continuity (0 ohms). If it shows no continuity, it has blown.
Tip: If the fuse is blown, inspect your cooling fan. If the fan isn't running, it will cause the new fuse to blow immediately.
⚠ Warning: Never bypass this safety device.
Evaluate the Main Control Board
If all other components test fine, the control board or selector switch may be the culprit. The board uses relays to route 240V to the broiler. Unplug the unit, access the rear console, and look for burnt traces or melted solder points near the broil relay. A faulty board will require a full replacement, costing between $150 and $400.
Tip: Carefully inspect the board for any visible heat damage.
⚠ Warning: Testing for live 240V at the board is extremely dangerous and should only be performed by a professional technician.
Brand-specific notes
Some brands have known design quirks worth knowing about before you start.
GE
GE and GE Profile models often hide the bake element, meaning the broil element handles much of the preheat load. If your preheat times have increased significantly, the broil element may be failing.
Whirlpool
Whirlpool and KitchenAid units often have a rear-mounted thermal fuse that is sensitive to fan issues. If the oven won't heat at all after a clean cycle, check this fuse first.
Samsung
Samsung ranges often suffer from relay failures on the control board. If the element is intact but won't heat, the PCB likely needs a swap, which can cost $150-$300.
LG
LG gas ranges frequently have weak igniters. Even if it glows orange, if it doesn't draw the correct 3.2 to 3.6 amps, the gas valve won't open. Always start your diagnosis here.
Sub-Zero/Wolf
Wolf ranges feature delicate infrared gas broilers. The ceramic tiles can easily crack from moisture or chemicals. Avoid using oven cleaners on these tiles and be aware that coastal humidity can impact their longevity.
What our techs see most often
Across the Pacific Northwest, we see a surge in broiler issues during the winter holidays. Many homeowners run the high-heat self-clean cycle to prep for guests, which can stress aging elements, blow thermal fuses, or fry control boards. My recommendation is to avoid the self-clean cycle before big events and stick to manual cleaning for older units.
When to call a professional
- → You need to replace a gas safety valve or work directly with the gas supply lines.
- → You need to diagnose complex control board voltage issues while the unit is live with 240V power.
- → You have a heavy built-in wall oven that needs to be completely uninstalled and pulled from the cabinetry to access rear components.
- → You suspect a wiring short in the main harness, often indicated by the smell of burning plastic or frequent breaker trips.
- → The appliance is still under the manufacturer's warranty, as DIY repairs will likely void your coverage.

Frequently asked questions
How much does it cost to replace an oven broil element?
DIY part costs are usually $25-$80. If you have an A-Fix technician handle it, total costs typically run $150-$250.
Why does my gas broiler glow but not light?
The igniter is likely too weak to pull the 3.2 to 3.6 amps required to open the safety valve. Replacing the igniter, which costs $40-$90, usually resolves this.
Can I still bake if my broiler is broken?
Usually, yes. However, since many ovens use the broil element to help with preheating, you may notice it takes much longer for the oven to reach the set temperature.
Did using the self-cleaning feature break my broiler?
It is quite common. The extreme heat of the self-clean cycle (up to 900°F) can cause old elements to break or thermal fuses to trip as a safety measure.
How do I know if the control board is the problem?
If the element, wiring, and fuses are all functional, but no voltage reaches the element during a broil cycle, the relay on the control board has likely failed. Boards cost $150-$400.
