How to Fix E40 Error

UNPLUG THE DRYER. This is a critical over-temperature fault. The number one cause is a clogged vent.
THOROUGHLY CLEAN THE ENTIRE VENT SYSTEM, from the lint screen to the outside of the house. This is mandatory.
After cleaning the vent, you must replace the safety thermostat that tripped. Remove the rear panel to access the heater assembly.
Locate the high-limit thermostat and the one-time thermal fuse on the heater can. Use a multimeter to test both for continuity. The one that is open (no continuity) is the one that blew.
Replace the blown thermostat/fuse. NEVER bypass a safety thermostat.
