Kenmore Dryer Error Code E24

E24 on a Kenmore dryer indicates a shorted control thermistor. The control thermistor is a resistance-based temperature sensor, and this code appears when the electronic control board detects a resistance reading outside the expected 50K ohm range. The dryer stops operating to prevent unsafe conditions caused by unreliable temperature data.

No, you should not continue using the dryer with an active E24 code. A shorted thermistor means the control board cannot accurately monitor temperatures inside the dryer. Operating the dryer in this condition could result in overheating or other damage to the appliance.

Resetting the dryer may temporarily clear the E24 code, but it will return if the underlying fault is not repaired. Because the code is triggered by an out-of-range resistance reading from the thermistor circuit, the error will reappear as soon as the control board checks the sensor again during operation. A proper diagnosis and component repair or replacement is required to resolve the issue permanently.

A knowledgeable DIYer can often diagnose and resolve E24 without a technician. The first step is to disconnect the thermistor wires and measure resistance with a multimeter. If the reading is not within 45K to 55K ohms, replacing the thermistor is the fix. If the thermistor reads correctly, inspecting and testing the wiring harness is the next step before considering a control board replacement.

If only the control thermistor needs replacement, parts typically cost in the range of $15 to $50 depending on the specific model. If the electronic control board is at fault, board replacement parts generally range from $80 to $200 or more. Adding professional labor will increase the total repair cost by roughly $75 to $150 depending on your area.
