Model compatibility: Electrolux reuses codes across series and model years, so E73 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
When an Electrolux dryer shows E73, the control is reporting inlet thermistor (ntc 2) error. The code narrows the diagnostic path, but it does not by itself prove which part needs replacement. Use the full model number before following any model-specific diagnostic procedure.
Signs
Symptoms you may notice
automatic drying may be inaccurate
temperature control may be inconsistent
cycle may end early or run too long
Why it happens
Possible causes
temperature sensor problem
sensor wiring issue
airflow-related temperature abnormality
electronic control problem
Before you call
Safe checks you can make
These are simple, non-hazardous checks only. If anything is unclear, stop and contact a technician.
Clean the lint filter and make sure the exhaust path is not restricted.
Let the dryer cool, disconnect power for several minutes, and retry once.
Do not access internal temperature sensors or wiring yourself.
A recurring code needs sensor and control-circuit testing.
Important safety warning. Stop immediately if you smell overheating, see electrical damage, the breaker repeatedly trips, or the drum is mechanically jammed. Otherwise, stop after one safe reset/check cycle if the code returns.

When to call a technician
Schedule dryer repair if E73 returns after the safe checks. A technician can test the model-specific circuits associated with inlet thermistor (ntc 2) error without guessing from the display alone.
Seeing this code on your Electrolux appliance?
Book a specialist visit for a clear estimate and approval before any repair.
It indicates inlet thermistor (ntc 2) error. Check the model number because code meanings can vary by dryer platform.
A brief power reset is reasonable when there is no sign of overheating, wiring damage, or a tripped breaker. If the code returns, the underlying issue still needs diagnosis.
Do not continue if there is overheating, restricted airflow, electrical behavior, or abnormal drum movement. Correct any simple external issue and test only once.
