The broiler is one of the most useful — and most overlooked — functions on your oven. It’s what gives steaks a sear, melts cheese perfectly on a casserole, and chars vegetables just right. So when you switch to broil and nothing happens, or the element glows for a moment and then cuts out, it’s worth understanding why. Broiler problems have a clear set of causes, most of which are diagnosable without taking apart your entire oven.
This guide covers every reason an oven broiler might stop working, how to identify the cause, and what to do about it. Tricity Repairs serves Coquitlam, Port Coquitlam, and Port Moody for all oven repairs.
How the Broiler Works
In electric ovens, the broiler element is the coiled heating element at the top of the oven cavity. When broil mode is selected, power is routed to this top element (rather than the bottom bake element). In gas ovens, a separate broiler burner — usually in a drawer below the main oven — ignites to produce direct high heat. The broiler is controlled by the oven’s thermostat, control board, and a relay or switch that directs power to the correct element.
Common Causes of a Broiler That Won’t Work
1. Burnt Out Broil Element (Electric Ovens)
The broil element sustains some of the highest temperatures in the oven and over years of use can develop cracks, burn-through spots, or breaks in the coil. Unlike the bake element which runs at moderate temperatures during most cooking, the broil element hits maximum heat every time it’s used — accelerating wear.
Visually inspect the broil element with the oven off and cool. Look for any visible damage: holes, burn marks, blistering, or a section that appears darker or deformed. A damaged element is usually obvious. You can also test with a multimeter — no continuity confirms the element has failed. Broil element replacement is one of the simpler oven repairs: the element typically attaches with two screws and two wire connectors accessible from inside the oven.
2. Faulty Broil Relay or Infinite Switch
The oven’s control board uses a relay to switch power to the broil element. When this relay fails or burns out, the control board sends the correct signal but power never reaches the element. Signs of a relay problem include the oven working perfectly on bake but completely failing on broil, with no visual damage to the element itself.
On some older ovens with mechanical controls, an infinite switch (selector switch) routes power to bake or broil. A failed switch prevents the broil setting from functioning while bake continues to work. Testing these components requires a multimeter and some disassembly.
3. Control Board Fault
Modern electronic ovens manage broil through the main control board. A failing board can lose the ability to activate the broil function while bake continues to work normally. This is typically diagnosed after confirming the element and relays are functional. For related oven issues, see: Oven Won’t Turn On? Simple Steps to Diagnose It.
4. Temperature Sensor Causing Premature Cutoff
The oven temperature sensor monitors cavity temperature and can signal the control board to cut the broil element if it reads an incorrect (too-high) temperature. If the broil element comes on briefly then shuts off, the sensor may be misreading temperature or the high-limit thermostat may be tripping prematurely. For more on temperature sensor issues, see: Oven Temperature Not Accurate? Here’s Why and How to Fix It.
5. Wrong Oven Setting or Mode
Before assuming a fault, confirm the oven is correctly set to broil — not a timed bake, a convection mode, or a temperature setting that only activates the bake element. Some ovens require the door to be left slightly ajar during broiling to prevent the thermostat from cycling the element off (the oven’s safety thermostat can shut the broil element down if the cavity temperature climbs too high with the door fully closed). Check your manual for the correct broiling procedure for your specific model.
6. Gas Broiler Igniter Failure (Gas Ovens)
In gas ovens, the broiler has its own igniter separate from the bake burner. When the broil igniter fails, you may hear a clicking sound as it attempts to spark, or no sound at all, but the burner doesn’t light. Gas broiler igniters wear out similarly to bake igniters — they become too weak to generate enough heat to open the gas valve. A failed igniter needs replacement and should only be handled by a qualified technician for gas appliances.
Step-by-Step Diagnosis (Electric Oven)
- Set oven to broil and observe — does the element glow at all? Briefly then cut out? Or nothing?
- Visually inspect the broil element (oven cold, power off) — look for holes, cracks, burn marks.
- Test element with multimeter — no continuity = failed element, replace it.
- If element tests fine — the relay, infinite switch, or control board is the next area to check.
- Check the temperature sensor — if broil cuts out quickly, sensor or high-limit thermostat may be tripping.
Can You Still Use the Oven If the Broiler Doesn’t Work?
Yes — a failed broil element doesn’t affect the bake function. You can continue using the oven for baking while the broil element is awaiting replacement. Just avoid selecting broil mode, and note that some ovens use both elements together during preheating — so preheating may be slightly slower than normal.

When to Call a Professional
Broil element replacement is a manageable DIY repair for most homeowners. Relay, switch, and control board diagnosis requires a multimeter and more disassembly — a technician can work through this efficiently. For gas oven broiler issues, always call a qualified technician.

Summary
A broiler that won’t work is most commonly caused by a burnt-out broil element, a failed relay or switch, or a control board fault. Inspect the element visually first — visible damage confirms replacement is needed. If the element looks fine but broil still doesn’t work, the relay or control board is the next area to investigate. Broil element replacement is one of the simpler oven repairs and immediately restores full broiling function.
