Electric Stove Burner Not Heating? Here's What Was Really Wrong
A step-by-step look at a real electric stove repair, from a dead burner to the fix
When an electric burner stops heating, most homeowners assume the coil is burned out and order a replacement. In this case, that was not what was happening. Here is the exact diagnostic process our certified technicians used to find the real cause and get the burner working again the same day.
Case Snapshot

Diagnosis

Time to Repair

Outcome
Burner heating on all settings
The Problem
An Oak Park homeowner called Dara Appliance Repair after the rear-left burner on her electric coil range stopped heating entirely. Turning the knob to any setting, low or high, produced nothing: no glow, no warmth, nothing. The other three burners worked normally.
She'd already bought a replacement coil element online, assuming that was the obvious fix, but wanted a technician to confirm before installing it herself. That turned out to be a good call.
The Diagnostic Process
Confirmed the symptom on-site
Our technician turned the affected burner through every heat setting. Nothing happened at any level, while the neighboring burner responded normally on the same settings.
Inspected the coil element visually
The element showed no visible burns, blistering, or damage, the most common visible signs of a failed coil. It looked no different from a working one.
Swapped the coil with a known-good element
Rather than trust appearances, the technician swapped in a coil from a working burner position. The burner still didn't heat, ruling out the coil element itself as the cause.
Tested the infinite switch with a multimeter
With the coil ruled out, the technician tested the burner's control switch for continuity across its settings and found it was failing to complete the circuit consistently, an intermittent internal fault.
Checked the wiring and terminal block
A final check of the wiring and terminal block behind the switch showed no damage or corrosion, confirming the switch itself as the sole cause rather than a wiring issue.
The Root Cause
A failing infinite switch, the control behind the knob that regulates power to the burner, not the coil element the customer had already ordered a replacement for. The coil looked and tested fine at every step. Without swapping it against a known-good element, it would have been easy to install a new coil, see no change, and assume the repair had failed.
The Fix
With the switch confirmed as the cause, our technician completed the repair in a single visit:
- Replaced the faulty infinite switch with a part matching the range's manufacturer specifications
- Reinstalled the original coil element, since it had already tested as fully functional
- Tested the burner across low, medium, and high heat settings to confirm consistent, accurate heating at every level
The Result
The burner now heats properly at every setting, and the customer's original coil element, still in good condition, went right back in rather than being replaced unnecessarily. The $89 diagnostic fee was waived since she moved forward with the repair, and the repair is backed by our standard 3-month warranty. As a first-time customer, she also received 10% off the total repair cost.
Common Causes of an Electric Burner Not Heating
| Cause | Signs | DIY-Fixable? |
|---|---|---|
| Burned-out coil element | Visible burns, blistering, or a bulge on the coil surface | Sometimes, on ranges with plug-in elements |
| Faulty infinite switch | Burner doesn't heat even after swapping in a known-good coil | No, replacement required |
| Loose or corroded terminal block | Burner heats intermittently or only at certain settings | No, requires inspection |
| Tripped breaker or blown fuse | Multiple burners or the entire cooktop not heating | Yes, check the breaker panel first |
| Damaged internal wiring | Burner unresponsive, possible burning smell near the control panel | No, call a professional immediately |

How to Prevent This
Make sure coil elements are fully and correctly seated in their sockets
Wipe up spills near control knobs promptly, before liquid can reach the switch behind them
Avoid forcing a stiff or hard-to-turn control knob
Check the breaker panel first if more than one burner stops working at once
Have a technician test the switch before buying a replacement coil, testing is often faster and cheaper than guessing
DIY vs. Call a Professional
Safe to Try Yourself
- Checking that the coil is fully seated in its socket
- Swapping the suspect coil with one from a working burner to test it (unplug the range first)
- Checking the breaker panel if multiple burners are out
Call a Professional
- Burner still doesn't heat after swapping in a known-good coil
- Any burning smell near the control panel
- Infinite switch testing or replacement
- Wiring or terminal block issues behind the controls
