If one coil burner won't heat, swapping it with a same-size burner that works is the fastest way to tell whether the coil has failed or the problem is in the socket or switch behind it. On most coil ranges the elements unplug by hand, so this takes a few minutes.
Safety first: Make sure every burner is off and cool, switch off the range's breaker before you unplug or plug in a coil, and leave socket wiring and switches to a professional.
Follow the diagnostic path
Step 1: Is the coil fully seated in its socket and lying flat?
If yes: Go to Step 2.
If no: Lift the coil slightly, pull it out, and push it straight back in until it sits level in the drip pan. A loose coil can heat poorly or not at all.
Step 2: Does the coil heat when you move it to a working socket of the same size?
If yes: The coil is fine; the problem is the original socket or its switch. Go to Step 3.
If no: The coil has failed. Replace it with an element that matches your model and size.
Step 3: Are the socket terminals blackened, pitted or loose?
If yes: The socket needs replacing, and the coil's terminals may also be damaged. That involves wiring, so call a technician.
If no: Go to Step 4.
Step 4: Does the burner heat only on high, or stay hot when switched off?
If yes: The control switch for that burner has likely failed. A technician can replace it.
If no: Go to Step 5.
Step 5: Did several burners, or the oven as well, stop at once?
If yes: Power to the range may be the issue. Ranges run on a double breaker, and a breaker fault, a damaged cord or a loose connection at the terminal block can cut power to part of the range. Reset the breaker fully off and on once; if that doesn't help, call a technician or electrician.
If no: A technician can trace the wiring between the switch and socket.
What your answer points to
| What you found | Most likely cause | DIY or technician |
|---|---|---|
| Coil loose in socket | Poor seating | DIY |
| Coil dead in any socket | Failed coil element | DIY replacement |
| Burned socket terminals | Damaged socket | Technician |
| Heats only on high | Faulty burner switch | Technician |
| Several burners out | Power supply issue | Technician or electrician |
Stop and call a technician if
- •You see sparks or scorching at the socket.
- •A burner won't turn off.
- •The breaker trips when you use a burner.
Keep it from coming back
- •Use flat pans that match the burner size.
- •Wipe spills once the coil is cool so food doesn't bake onto terminals.
- •Seat coils firmly after cleaning.
Owen's shop tip: If a coil sparked before it died, I replace the socket along with the coil. A pitted socket will damage a new element.
The same element-testing logic applies to the oven; see our guide to an oven broiler not working. For burner problems, call ProFix Boston at (617) 812-1425, or see our range repair service.
