Kenmore Dryer Error Code F3E5

F3E5 means the dryer's control board has detected that both the inlet thermistor and the exhaust thermistor are showing open circuit readings at the same time. Because both sensors fail simultaneously, this code is almost always caused by a disconnected or faulty P4/P14 connector at the Central Control Unit rather than two independent sensor failures. The thermistors are responsible for monitoring air temperatures inside the dryer, so this fault prevents safe temperature regulation.

It is not recommended to operate the dryer while F3E5 is active. The thermistors provide temperature feedback that the control board uses to regulate heating safely. Without reliable readings from both sensors, the dryer cannot properly control its heat output, which creates a potential overheating risk. The issue should be diagnosed and corrected before resuming normal use.

If the fix is simply reseating the P4/P14 connector, there is no parts cost and only a service call fee if a technician is involved, typically in the range of $75 to $150. If a thermistor needs replacement, parts generally cost between $15 and $50 each, with total repair costs including labor ranging from $100 to $250 depending on your location and service provider. Wiring harness repairs fall somewhere in between depending on the extent of the damage.

Start by locating the Central Control Unit inside the dryer cabinet and checking that the P4/P14 connector is fully plugged in and locked. If the connector is secure, inspect the wiring harness for damage, and check the connector pins for corrosion or bent terminals. If the wiring is intact, use a multimeter to test both thermistors for continuity and proper resistance values to determine if one or both need replacement.

A power reset may temporarily clear the error display, but the code will return as soon as the dryer runs and the control board checks the thermistor circuits again. Because F3E5 indicates an actual open circuit condition, the underlying cause, whether a loose connector, damaged wiring, or a failed thermistor, must be corrected for the error to stay cleared.
