Quick answer
E3 — Supply voltage is too high or too low
Model compatibility: Frigidaire reuses codes across series and model years, so E3 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
Plain language
What this code means
E3 is a control-reported condition, not an automatic proof that one component has failed. Wiring, sensors, airflow, water, mechanical restrictions and the control itself can produce similar displays.
Supply voltage is too high or too low. Platform note: FGIC3066TB-family standalone induction cooktop. Confirm the exact model family before applying a service procedure from another Frigidaire generation.
Signs
Symptoms you may notice
The appliance may show this behavior: code returns after a restart or at the same point in a cycle.
The appliance may show this behavior: appliance may stop, reset, refuse to start, or protect its electronics until the supply is normal.
The appliance may show this behavior: affected function may be disabled while other functions still operate.
The appliance may show this behavior: appliance may enter a protective state to prevent additional damage.
Why it happens
Possible causes
Diagnosis may need to consider incorrect household supply voltage — that possibility is not a confirmed failed part.
Diagnosis may need to consider loose or incorrect electrical connection — that possibility is not a confirmed failed part.
Diagnosis may need to consider supply-frequency problem — that possibility is not a confirmed failed part.
Diagnosis may need to consider damaged harness or power board — that possibility is not a confirmed failed part.
Diagnosis may need to consider electronic control sensing issue — that possibility is not a confirmed failed part.
Before you call
Safe checks you can make
These are simple, non-hazardous checks only. If anything is unclear, stop and contact a technician.
Turn the appliance off and check whether the circuit breaker has tripped. Stay within normal owner access and stop if a safety warning appears.
Confirm the appliance is connected to the voltage specified on its rating label. Stay within normal owner access and stop if a safety warning appears.
Do not probe live terminals unless you are qualified to do so. Stay within normal owner access and stop if a safety warning appears.
If the home supply is suspect, use a licensed electrician before replacing appliance parts. Stay within normal owner access and stop if a safety warning appears.
Do not bypass door or lid locks, open sealed refrigeration systems, service microwave high-voltage sections, or dismantle internal gas or induction power modules.
Important safety warning. Stop using the appliance for smoke, arcing, a burning-electrical smell, repeated breaker trips, uncontrolled heating, or water reaching electrical parts. For persistent gas odor, leave the area and follow local gas-emergency guidance. Do not dismantle internal gas or induction power modules.

When to call a technician
If E3 returns after the safe external checks, or the appliance shows a safety warning, professional diagnosis is appropriate. A technician should confirm the Frigidaire model and test the implicated system rather than replacing a part from the code description alone.
Seeing this code on your Frigidaire appliance?
Book a specialist visit for a clear estimate and approval before any repair.
Supply voltage is too high or too low That technical note still has to be confirmed against the exact model and control generation.
Record the code first. One controlled reset can be reasonable when there is no safety warning. Repeated resets are not a repair.
No. The code can point to a system while the failed item is wiring, a restriction, a sensor, or another connected component.
