Understanding the Problem
What this covers: "Burner unit" can mean the electric surface element (coil or sealed radiant) and its hardware on electric Whirlpool ranges, or the burner head/cap and igniter on gas Whirlpool ranges. Below are diagnostic steps and step-by-step replacement instructions for both types. Diagnostic steps (both types) 1. Note model: Record the exact Whirlpool model number (on the oven frame behind the door, on the range back, or inside the storage drawer). You need it to order the correct part. 2. Visual inspection: Look for cracks, burn marks, melted insulation, corrosion, clogged gas ports, or broken igniter tips. 3. Basic functional check: For electric — does the burner glow/hot? For gas — does the burner click and then light? Is flame present and even? 4. Isolate power/gas: Unplug the range (or turn off breaker). For gas, turn off the gas supply before working. Electric burner replacement (coil or sealed/radiant) 1. Tools: multimeter, screwdriver set, nut driver, needle-nose pliers, replacement element or top panel parts. 2. Confirm fault: Remove coil element from the socket and visually inspect terminals. Use a multimeter set to ohms. An open (infinite) reading between the element terminals means the element is failed. A short to ground (continuity between a terminal and element shell/ground) indicates internal short. 3. Replace simple coil element: Pull the coil straight out of the receptacle, disconnect from the plug-if style, insert new coil into the receptacle, test on low power. If the coil uses a terminal block under a ceramic block or screws, disconnect power, remove top element, detach element leads, install new element and secure terminals. 4. Replace sealed/glass-ceramic element: Remove screws securing the cooktop or lift the top per your model's service guide, disconnect wires from the element terminals, remove retaining clips and lift out the old element. Install new element and reassemble, ensuring proper gasket/seal seating. 5. If element tests good but burner won’t heat: Test the infinite/temperature control switch at the back of the knob assembly for continuity or that it gives power when turned on. Replace switch if defective. Also check the terminal block that connects the element wiring to the range wiring. Gas burner replacement (head/cap/igniter) 1. Tools: screwdriver set, nut driver, small brush or compressed air, replacement burner head/cap or igniter, adjustable wrench. 2. Confirm fault: If burner won’t light or flame is weak/uneven, remove the burner cap and head, inspect ports for debris or rust. If you hear clicking but no spark at the electrode or see no sparking, the igniter may be cracked or fouled. 3. Clean first: Remove caps and heads, clean ports with a soft brush and compressed air. Reassemble and test. If still faulty, proceed to replace parts. 4. Replace burner head/cap: Lift off cap, remove screws or mounting clips holding the head, disconnect igniter lead if necessary, install new head and cap, reattach igniter and test. 5. Replace igniter electrode: Disconnect power and gas, disconnect the igniter wiring harness at the switch or module, remove mounting screw for the igniter, replace with new igniter, reconnect wiring, restore gas and power, and test ignition and flame. Testing and verification 1. Electric: After reassembly, restore power and test each heat setting. Watch for even heating and no arcing or burning smells. 2. Gas: Turn gas on, test ignition sequence; burner should click and light to a steady, even blue flame. If flame is yellow or sooty, turn off and check or call a pro. Safety note: Always disconnect electrical power at the breaker and turn off gas supply before servicing. If you smell gas, stop immediately, ventilate, do not operate electrical switches, and call your gas utility or a qualified technician. If you are not comfortable working with gas valves or internal wiring, hire a qualified technician.
Common Symptoms
Burner does not heat or lights inconsistently; burner glows but does not heat (electric), clicking but no flame or weak/uneven flame (gas); visible burn/damage or cracked igniter.
Common Causes
- Failed surface element (open circuit or short to ground)
- Faulty infinite/heat control switch or terminal block connections
- Clogged gas ports, cracked/fouled igniter, or damaged burner head on gas ranges

Helpful Repair Tip
To confirm an electric element is bad, pull it out and check continuity with a multimeter — an infinite reading means replace it. For gas, watch for spark at the igniter when attempting to light; no spark usually means a bad igniter or wiring.
Frequently Asked Questions
How do I find the correct replacement burner for my Whirlpool range?
Locate the range model and serial number (sticker on the oven frame behind the door, on the left/right frame, or on the back). Enter that model number on an authorized parts website or Whirlpool parts lookup to find the exact element/burner/igniter part number. Do not rely on physical appearance alone — many burners look similar but have different terminal shapes or mounting specs.
Can I replace the burner myself and how long will it take?
Yes — if you are comfortable with basic hand tools and safety procedures. Replacing a simple electric coil element can take 5–20 minutes. Replacing a sealed radiant element or doing a gas burner/igniter replacement can take 30–90 minutes depending on access and model. If you are unsure about working with gas or internal wiring, hire a qualified technician.
