Error codeE42

E42 quick answer
Meaning: the dryer’s door-shut sensing reports an error; the owner guide words it as “Door Open”
Guide advice: confirm that nothing obstructs the door and that you have closed it fully
Documented in: the owner guide, plus tech data sheets A11199902 and 137265000B
Beyond the door itself
The older sheet calls this a door sensing failure. It names a faulty electronic control board as the condition and replacing that board as the remedy. Such a repair belongs to a technician, and the dryer must be unplugged before it is opened.
Codes often mistaken for it
E41: the door stood open at the moment the cycle began
E4: the humidity sensor failing, unrelated to the door
Electrolux dryer repair in San Francisco
Once the door is clear and fully shut but E42 stays lit, call (415) 449-0036 from San Francisco or the Bay Area and ask about Electrolux dryer repair. Say that you already checked the door, and give the model number.
Model compatibility: Electrolux reuses codes across series and model years, so E42 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
