Kenmore Dryer Error Code tE4

The tE4 code on a Kenmore dryer indicates that the steam generator thermistor has been detected as either open or shorted. This means the temperature sensor in the steam generator is not functioning within its expected resistance range. The code only appears during the dryer's test mode, not during standard drying cycles. The primary recommended repair is replacement of the steam generator assembly.

Because tE4 only displays during test mode and not during normal operation, a reset may cause the code to stop appearing temporarily. However, since the code reflects an actual hardware fault with the steam generator thermistor, resetting the dryer will not repair the underlying problem. The fault is likely to reappear the next time a diagnostic test is run until the defective component is replaced.

Repair costs depend on whether the issue is a simple wiring fix or requires a full steam generator replacement. If only the wiring harness or connector needs attention, costs may be minimal. If the steam generator assembly must be replaced, parts alone can range from roughly 80 to 200 dollars depending on the specific model, with additional labor costs if a technician performs the work. Getting a firm quote before proceeding is advisable.

A knowledgeable DIYer can attempt this repair by inspecting the wiring harness and connector leading to the steam generator thermistor for obvious damage or corrosion. If the wiring looks intact, replacing the steam generator assembly is the next step and requires basic disassembly of the dryer cabinet. If you are not comfortable working with appliance wiring or disassembling the unit, a qualified technician is recommended.

Since tE4 only activates in test mode and does not interrupt normal drying cycles, the dryer may continue to operate for basic drying functions. However, the steam feature should not be relied upon when this fault is present, as the steam generator thermistor is not functioning correctly and the system cannot properly regulate steam generator temperature. Continued use of the steam cycle under these conditions could risk further damage to the assembly.
