Electrolux Dryer Error Code E64

E64 indicates a heater sensing alarm or, on heat pump models, a compressor sensing alarm caused by a failure in the sensing circuit on the main control board. The board is unable to read a valid signal from the circuit that monitors the heater or compressor. The dryer stops operation when this code appears to prevent further damage. Diagnosis should begin with the main board and the wiring connected to the heating system.

No, you should not continue operating the dryer while E64 is active. The code indicates the control board cannot monitor the heater or compressor properly, which means a fault condition could go undetected during a cycle. Stop using the dryer and address the error before running any loads to avoid the risk of overheating or further component damage.

Repair costs depend on what component has failed. Wiring repairs or connector reseating are generally inexpensive, typically in the range of a standard diagnostic fee plus minimal parts cost. A replacement heater element usually runs in the range of $30 to $80 for the part, while a new main control board can cost between $100 and $250 or more depending on the model. Labor charges from a technician add to all of these estimates.

Some steps are accessible to a knowledgeable DIYer, such as checking wiring harness connectors for looseness or corrosion and inspecting the heater element for continuity. However, if the main control board sensing circuit itself has failed, replacing the board requires comfort with disassembling the dryer and handling electronic components. If you are not confident with those tasks, a qualified appliance technician is the safer option.

A power reset may temporarily clear the code, but if the underlying sensing circuit fault remains, E64 will return when the dryer attempts to operate. Resetting alone does not repair a damaged board circuit, a failed heater element, or a wiring issue. The root cause must be diagnosed and corrected for the error to stay cleared.
