Mabe Dryer Error Code E24

E24 on a Mabe dryer indicates a shorted control thermistor. The control thermistor is a resistance-based temperature sensor, and its reading has fallen outside the acceptable 50K ohm range. The dryer's electronic control board detected this abnormal reading and triggered the fault code to alert you to a problem in the temperature sensing circuit.

It is not recommended to continue using the dryer while E24 is active. A shorted thermistor means the control board is not receiving accurate temperature data, which can result in improper heating cycles or potential overheating. Stopping use until the fault is diagnosed and repaired is the safer course of action.

Repair costs depend on which component is at fault. A replacement thermistor is generally the least expensive part in the repair, with parts typically ranging from a modest to moderate cost. If the electronic control board requires replacement, parts costs will be significantly higher, and adding professional labor will increase the total. Getting a diagnosis first helps avoid paying for parts that are not needed.

A knowledgeable DIYer can diagnose this code by disconnecting the thermistor and measuring its resistance with a multimeter. If the reading is not within 10 percent of 50K ohms, the thermistor needs to be replaced. If the thermistor tests correctly, checking the wiring harness for damage is the next step before concluding the control board needs replacement. Working inside a dryer involves electrical components, so always unplug the appliance before beginning any inspection.

Resetting the dryer by unplugging it briefly may temporarily clear the display, but the E24 code will return if the underlying fault in the thermistor or its circuit is still present. A reset does not repair a shorted thermistor, damaged wiring, or a faulty control board. A proper repair is necessary to resolve the fault permanently.
