Whirlpool Washer, Dryer Error Code TIMED (flashing)

The flashing TIMED code on a Whirlpool dryer indicates that the control board has detected an open or shorted condition in the thermistor or its wiring circuit. The thermistor is the component responsible for monitoring exhaust air temperature during the drying cycle. Without a valid thermistor signal, the control cannot properly manage timed or automatic drying functions. The fault must be resolved by replacing the thermistor or correcting the wiring fault before normal operation can resume.

Running the dryer with a flashing TIMED code is not recommended. The thermistor provides critical temperature feedback to the control board, and without it the dryer cannot properly regulate heat levels during a cycle. Operating without a functioning thermistor circuit risks overheating, which could damage clothing, internal components, or in a worst-case scenario create a fire hazard. The fault should be diagnosed and corrected before resuming use.

Resetting the dryer by unplugging it for a few minutes may temporarily clear the fault display, but the code will return if the underlying thermistor or wiring fault has not been corrected. Because this code reflects an actual electrical fault in the thermistor circuit rather than a transient software glitch, a reset alone is not a fix. The thermistor should be tested and either replaced or the wiring corrected to permanently resolve the fault.

Start by unplugging the dryer and locating the thermistor, which is typically mounted on the exhaust duct or blower housing. Disconnect the thermistor and test it with a multimeter: an open or shorted reading confirms a failed component that needs replacement. If the thermistor tests within a reasonable resistance range, inspect the wiring harness and connectors between the thermistor and control board for damage, loose terminals, or broken wires, and repair any faults found.

If the thermistor itself has failed, the part typically costs in the range of $10 to $40 depending on the specific model. Professional labor for the diagnosis and repair can add $75 to $150 or more depending on your location and service provider. If the issue is only a loose connector or minor wiring repair, costs can be minimal. Replacing the thermistor is generally a straightforward repair that many experienced DIYers can handle with basic tools.
