Electrolux Dryer Error Code E43

E43 indicates an incongruency in the door interlock sensing signal. The control board is receiving a signal from the door interlock that does not match a valid expected state, either locked or unlocked. This triggers a fault to prevent the dryer from operating unsafely. The fault can originate from the interlock switch, the wiring, or the control board.

You should not continue using the dryer while the E43 code is active. The door interlock is a safety circuit designed to ensure the door is securely closed before and during operation. An incongruency in this circuit means the dryer cannot confirm the door is properly secured, which presents a safety risk. Resolve the fault before running any cycles.

Repair costs vary depending on the faulty component. A replacement door interlock switch typically costs between $15 and $50 for the part. If the control board is at fault, parts alone can range from $100 to $300 or more. Adding professional labor, total repair costs generally fall between $100 and $400 depending on the diagnosis and parts required.

Some causes of E43 are accessible to a knowledgeable DIYer, such as reseating loose connectors, inspecting wiring for visible damage, or checking the door latch alignment. Replacing the door interlock switch is a moderate repair that requires disassembly of the door panel. If the control board needs replacement, that is a more involved repair that some DIYers may prefer to leave to a technician.

A power reset, such as unplugging the dryer for a few minutes and restoring power, may temporarily clear the E43 code if the fault was caused by a transient signal issue. However, if the underlying problem is a worn interlock switch, damaged wiring, or a failing control board, the code will return. A reset should be seen as a diagnostic step, not a permanent fix.
