GE Range Burner Won't Heat — 5 Terminal Block Failures & Fixes

You turn the knob, wait for the familiar glow, and... nothing. The burner stays cold. Before you start Googling new ranges, there's a small connector block behind that burner element that fails more often than most techs want to admit.

The terminal block (part WB17T10006) is where your burner element plugs into the range's electrical system. It's basically a junction box with metal terminals that carry 240 volts to heat your element. When these terminals corrode, loosen, or burn out, your burner goes dark — even though the element itself might be perfectly fine.

Quick Diagnostic Check

• The burner element won't heat at all — most common sign of terminal block failure
• Burner heats intermittently — terminals are loose or partially corroded
• You smell burning plastic near the burner — terminals are arcing and melting the block
• The element glows on one side only — one terminal has failed while the other still works
• Breaker trips when you turn on that burner — severe terminal damage causing a short

Cause #1: Corroded or Burned Terminal Contacts (65% of Cases)

Here's what happens: Every time you use a burner, the terminal block heats up. Over years of thermal cycling, the metal terminals oxidize and corrode. This creates resistance, which generates even more heat, which accelerates the corrosion. Eventually you get a feedback loop that ends with blackened, pitted terminals that won't conduct electricity properly.

How to diagnose: Turn off the breaker. Pull the burner element straight out — it should slide out with firm pressure. Look at the two prongs on the element and the receptacle terminals they plug into. If you see black carbon buildup, discoloration, or pitting, that's your problem.

The fix: Replace the terminal block (WB17T10006 fits most GE, Hotpoint, and Kenmore ranges). The part costs around $18. If the element prongs are also damaged, replace both — a new element won't fix a burned terminal block, and a new terminal block won't fix damaged element prongs.

Probability: Very High. This is the most common reason a burner won't heat when the element itself looks okay.

Cause #2: Loose Wire Connections Behind the Block (20% of Cases)

The terminal block doesn't just hold the element — it also connects to the range's internal wiring with screw terminals or push-on connectors. These can vibrate loose over time, especially if you slide your range in and out for cleaning.

How to diagnose: After removing the element, locate the terminal block mounting screws (usually two screws holding it to the range body). Remove these and gently pull the block forward. Check if the wire connections wiggle or pull off easily. They should be snug.

The fix: If the wires are just loose, tighten the screw terminals or push the connectors firmly onto the terminals. If the wire insulation is heat-damaged or brittle, you'll need to cut back to fresh wire and install new crimp connectors before reattaching.

Probability: Moderate. Worth checking if the terminal block itself looks okay but the burner still won't heat.

Cause #3: Cracked or Melted Terminal Block Housing (10% of Cases)

The ceramic or high-temp plastic housing that holds the metal terminals can crack from mechanical stress or melt from excessive heat. Once the housing is compromised, the terminals can short against the metal range body.

How to diagnose: Inspect the terminal block housing for visible cracks, burn marks, or melted areas. Sometimes the damage is on the back side where you can't see it until you remove the block completely.

The fix: Replace the terminal block assembly. You can't repair a cracked housing — it's a safety hazard that could cause a short or fire.

Probability: Low to Moderate. More common in older ranges (15+ years) or if someone forced the element in at an angle.

Cause #4: Wrong Element Creating Poor Contact (3% of Cases)

Not all burner elements are created equal. If someone replaced your element with an aftermarket part that doesn't quite match the original specs, the prongs might not seat properly in the terminal block.

How to diagnose: Check if the element prongs are the right diameter and spacing for the terminal block receptacles. The prongs should slide in with moderate resistance — not too loose, not requiring excessive force.

The fix: Get the correct OEM or quality aftermarket element for your range model. Cross-reference your model number against the compatible models list to ensure proper fit.

Probability: Low. Only relevant if the element was recently replaced.

Cause #5: Failed Infinite Switch or Surface Unit Switch (2% of Cases)

The terminal block might be fine, but no power is reaching it because the control switch itself has failed. The infinite switch (that's the technical name for your burner control knob) regulates power to the element.

How to diagnose: If you have a multimeter, test for continuity through the switch at various settings. You can also swap the suspect burner's control knob wiring with a working burner to see if the problem moves.

The fix: Replace the infinite switch for that burner. Note the terminal configuration and wire colors before disconnecting anything.

Probability: Very Low. Usually you'd see erratic heating behavior before complete failure, and the terminal block would show no signs of damage.

When to Call a Pro

Replacing a terminal block is straightforward — turn off the breaker, remove two screws, disconnect a couple wires, reverse the process with the new part. It's a 15-minute job if nothing's seized up.

Call a tech if:

• You're not comfortable working with 240V circuits (understandable — it'll bite you)
• Multiple burners failed simultaneously (suggests a problem with the main terminal block or breaker)
• The wiring behind the terminal block is extensively heat-damaged
• You smell gas anywhere near the range (wrong problem entirely — evacuate and call your gas company)

Expect to pay $150–$250 for a service call plus the part. The part itself runs about $18 for WB17T10006, so you're mostly paying for the tech's time and expertise.

Frequently Asked Questions

Can I replace just the terminals without replacing the whole block?

Technically yes, but no. Individual terminals are available, but by the time one terminal has failed, the others are usually degraded too. The ceramic block itself may also have stress cracks you can't see. For $18 and 15 minutes of work, replace the whole assembly and get another decade of reliable service.

Will WB17T10006 fit my Kenmore range?

Most likely — GE manufactured many Kenmore ranges under private label. Check your model number against the compatibility list. The terminal block is a pretty generic part; what matters is the mounting hole spacing and terminal configuration. If your old block has two terminals in the same orientation as WB17T10006, you're good.

Why did my terminal block fail — am I doing something wrong?

Nope. It's normal wear. Every heating/cooling cycle causes the metals to expand and contract at different rates. Over thousands of cycles, this creates microscopic gaps that allow oxidation. You can extend terminal block life by avoiding ultra-high heat settings when possible and making sure the element is fully seated, but eventually physics wins. Plan on replacing terminal blocks every 10–15 years on a heavily-used range.
