Electric Cooktop Element Repair
Southern California
01 · Two architectures, two repair playbooks
An electric cooktop element that won't heat usually comes down to a burned-out heating coil, a failed infinite control switch, or a damaged terminal block from arcing. Our techs at Same Day Appliance Repair test the element resistance with a multimeter first because that gives definitive yes/no on the element itself — and a coil-style element swap runs $185 to $285, while a glass-top radiant element runs $245 to $385.
Coil cooktops have visible spiral metal heating elements that plug into receptacles in the cooktop surface. Most LA rentals and pre-2010 homes have these (Frigidaire FFEC, GE JBP, older Whirlpool). Plug-and-replace architecture, simpler repair.
Radiant glass-top cooktops have heating elements mounted under a smooth glass-ceramic surface that glows red when active. Newer (KitchenAid, GE Profile, Samsung NE, LG, Whirlpool flat-top). More complex repair (partial glass-top lift required), higher parts cost.
Neither is induction. Induction uses a magnetic field to heat the pan directly with no surface element glow. See induction not working for that scope.

02 · Coil cooktop element failure (year 6 to 10)
Across LA, OC, Ventura, San Bernardino, and Riverside, roughly 5 of every 10 "element dead" calls on coil cooktops land on the element itself, 3 of 10 on the terminal block (year 8+), and the remaining 2 on the infinite switch.
Coil elements typically last 6 to 10 years on rentals with heavy use, 10 to 15 years on lower-volume households. Failure mode is visual: a burnout pattern shows a section glowing red while the rest stays dark, or no glow at all on the affected element.
Replacement is straightforward: lift the element from the receptacle, replace with same-spec part, plug back in. $200 to $360 with labor.
Often paired failure: terminal block at the receptacle. The contact points where the element pins meet the cooktop body wiring corrode or melt from sustained high-amp use. If the new element doesn't heat, the terminal block is the next suspect ($260 to $420).
03 · Radiant glass-top element failure (year 7 to 10)
Radiant elements are mounted under a glass-ceramic cooktop surface. Visual diagnostic: turn the affected zone on at high heat, look for the red glow under the glass. No glow or partial glow with adjacent zones glowing brightly indicates element failure.
Replacement requires partial glass-top removal to access the element from below. Skill matters: glass-ceramic surfaces are tempered but not impact-resistant during removal, careful handling prevents accidental cracking. $300 to $540 with labor.
If the glass cracks during element replacement (rare with experienced technicians but possible on year-10+ glass with hidden stress fractures), surface replacement is needed; see surface cracked.
04 · Surface unit switch (infinite switch)
The surface unit switch (also called infinite switch) is the variable-power control behind each knob. Mechanically rotates between off and high through continuously variable settings. Wears with use; common failure modes: knob feels mushy or doesn't click into stops, no power to element regardless of knob position, or partial power only at high setting.
Test by swapping the suspect switch with a known-good zone temporarily. $200 to $360 replacement.
05 · Touch-control board (newer glass-tops)
Newer radiant glass-top cooktops (Samsung NE, LG, GE Profile) use capacitive touch interfaces instead of physical knobs. Touch control board sits under the front glass area, sensing finger contact through the glass. Failure modes: ghost touches, dead zones in the interface, full board failure.
Replacement $440 to $720 mid-market. We check for trapped moisture or burned-spice residue under the glass first; sometimes cleaning the interface area resolves intermittent ghosting without parts.

Composite examples; model numbers, ages, and prices are accurate to typical scope.
Front-right zone dead, no glow. Diagnosed: radiant element under glass burned out. Lifted glass partially, replaced element, reseated glass, tested all four zones at high heat with even glow. Total: $89 plus $310 element plus 1 hour = $440.
Two zones partially heating. Diagnosed: terminal blocks at both receptacles corroded from sustained heavy use, plus left-rear coil element open-circuit. Replaced both terminal blocks and the bad element. Total: $89 plus $480 parts plus 1.5 hours = $580.
Front-left knob mushy, zone power inconsistent. Diagnosed: surface unit switch worn. Replaced switch, tested click stops and power output through full range. Total: $89 plus $200 part plus 45 minutes = $290.
Touch-control interface ghost-activating zones. Diagnosed: control board capacitive sensor degradation, plus burned-spice residue under the glass at the interface area. Cleaned interface, replaced control board (Miele OEM, premium part). Total: $89 plus $580 board plus 1.5 hours = $780.
Two adjacent zones dead. Diagnosed: shared control board section failed (Samsung architecture groups two zones under one board section), plus one of the elements also damaged. Replaced board and element together. Total: $89 plus $720 parts plus 2 hours = $920.

Three common causes. (1) Heating element itself burned out — visible on coil cooktops as a black break in the spiral, or on radiant glass-tops as no red glow under the affected zone while others glow normally. (2) Surface unit / infinite switch failed — the variable-power switch behind the knob. Symptom: knob feels mushy, no power to the element regardless of setting, or only high-heat works. (3) Terminal block corrosion on coil cooktops — high amperage degrades the plug-receptacle contact over years (especially year 8 to 12 rentals). Our techs at Same Day Appliance Repair multimeter test the element first because it's definitive: open-circuit resistance means the element is dead, normal resistance means look upstream. $89 residential diagnostic, applied toward repair.
On coil cooktops it's plug-and-replace: lift the element out of the receptacle by tipping it up, pull straight out, slot the new same-spec element back in until it seats. Parts run $200 to $360 per zone. On radiant glass-top cooktops the work is more involved: the element mounts UNDER the glass, so the glass-ceramic top must be partially lifted to access it from below. Glass-top lift on year-10+ units carries crack risk — hidden stress fractures can propagate during removal. Most homeowners stop here and call us; $300 to $540 per zone. Whichever architecture you have, test the new element at high heat for even glow before reassembling the cooktop. Same-day across LA, OC, Ventura.
Coil cooktops have visible coiled metal heating elements that plug into a receptacle (older architecture, common in rentals and pre-2010 homes; Frigidaire FFEC, GE JBP, older Whirlpool). Radiant glass-top cooktops have heating elements under a smooth glass-ceramic surface that glows red when active (newer; KitchenAid, GE Profile, Samsung NE, LG). Different repair scope: coil elements plug-and-replace ($200 to $360), radiant elements require partial glass-top removal ($300 to $540).
Both are common. Element burnout shows visual evidence (burned-through coil section, dim or no glow on radiant elements). Surface unit switch (the infinite switch behind the knob) failure shows no power to the element regardless of element health. We test both at the diagnostic, switch first if multiple zones fail or if the knob feels mushy.
On coil cooktops, the terminal block is the receptacle where the coil element plugs into the cooktop body. High amperage flows through this connection on every cooking cycle. Over years (especially year 8-12 on rentals with heavy use), the connection corrodes or melts at the contact points. Symptom: element gets hot at the plug end but not the cooking surface. Replacement $260 to $420.
Depends on the failure. Single element burnout, $200 to $360 repair on a $400 to $800 cooktop usually pencils out. Multi-component failure (terminal block plus element plus switch) on a year-12 unit, you're at $700 to $900 repair against a $700 to $1,200 replacement, that's a real replace-vs-repair conversation. We give you the math at the diagnostic.
Yes, though premium electric (non-induction) is rare in LA. Most premium customers run gas or induction. When we do see a Miele KM or Gaggenau electric cooktop, control board failure runs $480 to $780. Element replacement is similar to mid-tier in cost because element technology is largely commoditized.
