Quick answer
E1-73 — Induction generator/power board is too hot on module 1
Model compatibility: Frigidaire reuses codes across series and model years, so E1-73 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
E1-73 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.
Induction generator/power board is too hot on module 1. Platform note: ES502I / modular induction platform. 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 pause, disable a function, or return the same code after a restart.
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 temporary electronic issue — that possibility is not a confirmed failed part.
Diagnosis may need to consider wiring or connector problem — that possibility is not a confirmed failed part.
Diagnosis may need to consider failed sensor or actuator associated with the code — that possibility is not a confirmed failed part.
Diagnosis may need to consider incorrect configuration — that possibility is not a confirmed failed part.
Diagnosis may need to consider failed electronic control — 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.
Power-cycle the appliance once. Stay within normal owner access and stop if a safety warning appears.
Check for an obvious user-accessible obstruction or installation issue. Stay within normal owner access and stop if a safety warning appears.
Record the full model number and the exact way the code is displayed. Stay within normal owner access and stop if a safety warning appears.
Avoid internal electrical testing unless qualified. 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 E1-73 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.
Induction generator/power board is too hot on module 1 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.
