Frigidaire Refrigerator Error Code Et

The Et code on a Frigidaire refrigerator means the control board detected a horizontal or level switch error, specifically that it stopped receiving pulse signals from that switch for a period of time. In response, the control board automatically switches to a time-based supply mode to keep the unit operating. The code points to a problem with the level switch, its wiring, a mechanical obstruction, or in rarer cases, the control board itself.

The Et code is not a safety hazard. The refrigerator automatically shifts to a time-based supply mode when this error is detected, so the unit continues to operate. Food safety is not immediately at risk, but the ice or water dispensing system will not perform with full accuracy until the underlying issue is resolved.

A power reset may temporarily clear the Et code from the display, but if the underlying fault, such as a failed switch, damaged wiring, or mechanical obstruction, has not been corrected, the code will return once the control board again fails to detect pulse signals. A reset is useful for confirming whether the issue is intermittent, but it is not a permanent fix.

Some causes of the Et error are DIY-friendly. Checking for ice buildup or physical obstructions in the ice maker area, and inspecting wiring connectors for looseness or corrosion, can be done without specialized tools. Testing or replacing the level switch requires a multimeter and some familiarity with appliance wiring. Control board replacement is more involved and may be better handled by a qualified technician.

Repair costs depend on the cause. Clearing a mechanical obstruction costs nothing beyond your time. A replacement level switch typically runs in the range of $15 to $60 for the part. If a control board replacement is needed, expect part costs in the range of $100 to $300 or more, plus labor if you hire a technician.
