Introdução
Non-responsive burners on a Frigidaire glass-top range are usually caused by a power supply problem, a burned terminal block, a failed infinite switch, or a bad radiant element. This guide walks you through safe electrical tests with a multimeter and shows how to replace any component that proves faulty. Follow these instructions if a single burner or the entire cooktop refuses to heat.

Peças
-
-
Partially unplug the range cord, place meter probes on each flat prong and the neutral to verify 120 V per leg and 240 V across both hots.
-
If probe contact is poor, unplug the cord fully and measure inside the receptacle instead.
-
-
-
Reset the range breaker fully off and on if either 120 V leg is missing.
-
Contact a licensed electrician if proper voltage cannot be restored at the receptacle.
-
-
-
Slide the stove out and locate the terminal block where the cord enters the chassis.
-
Look for scorched insulation, loose lugs, or melted plastic on the block and incoming wires.
-
Replace the terminal block if any damage is present before continuing tests.
-
Measure 120 V from each hot to neutral and 240 V across both hots at the block to confirm supply integrity.
-
-
-
Unplug the range and remove the quarter-inch hex screws securing the rear cover to expose the infinite switches.
-
-
-
Grip each spade connector with needle-nose pliers and pull them from L1 L2 H1 H2 P1.
-
Attach meter leads to L1 and H1 or to L2 and H2 and set the meter to continuity or resistance.
-
Rotate the burner knob; a closed circuit should appear on any active heat setting.
-
A persistent open reading identifies the infinite switch as defective.
-
-
-
Leave the outgoing element wires disconnected and place meter leads on H1 and H2.
-
A resistance between 10 Ω and 70 Ω confirms that the element circuit is intact.
-
An OL or very high resistance reading indicates an open element or broken wiring.
-
-
-
Remove wires from an Ego dual or triple switch and locate matched pairs such as 2-2A and 4-4A using the printed schematic.
-
Clip the meter to a matched pair and turn the knob to the corresponding ring size; continuity should appear for each active coil.
-
No continuity on any coil pair points to a failed switch.
-
-
-
Connect the meter to the matched outgoing wires for each coil and measure resistance.
-
Values outside 10–80 Ω or an open loop indicate a damaged burner element.
-
-
-
Pull the control knob forward to remove it from the shaft.
-
Undo the two Phillips screws and withdraw the faulty switch from the panel.
-
Transfer each wire to the identical-labeled terminal on the replacement switch.
-
Reinstall the switch, tighten the screws, and press the knob back onto the shaft.
-
-
-
Remove the three Phillips screws along the top lip of the oven cavity and slide the cooktop forward.
-
-
-
Remove the single hex screw on each side of the metal cross-bracket that supports the elements.
-
Lower the bracket with the burners onto the range chassis so the wiring is accessible.
-
-
-
Inspect each heating coil for cracks, scorching, or displaced ribbon.
-
Check every spade terminal for heat damage or corrosion.
-
Spot-test continuity from each male spade to the nichrome ribbon; an open reading confirms failure.
-
-
-
Position the old clip set on the new element in the identical labeled holes and tighten the screws snugly.
-
Flip the element over and push each clip until it snaps fully into the support bracket.
-
-
-
Match each wire to the identical letter or number on the new element using the photo for reference.
-
If a lead is too short, crimp the supplied splice and cover it with the insulation sleeve to prevent shorts.
-
-
-
Plug the range in and momentarily energize the new burner to confirm both ring sizes glow evenly.
-
-
-
Lift the burner assembly back into position and align bracket holes with chassis holes.
-
Install the hex screws, then lower the glass top and engage the rear locating tabs.
-
Reinstall the three oven-lip screws to lock the top in place.
-
-
-
Slide the range back to its original position and verify all burners cycle on and off correctly.
-
With voltage confirmed, components tested, and any failed parts replaced, your Frigidaire smooth-top stove should heat reliably. Recheck all screws and wire connections after the first cooking cycle and always disconnect power before future service.
