Frigidaire dryer — Error Code E64
The electronic control board has identified an open circuit within the heating element or the associated safety thermostats.
What it means
The E64 error on a Frigidaire dryer points to a Heater Open Circuit. The main electronic control board continuously monitors voltage across the heating system. When the board attempts to engage the heater relay but detects no continuity, it halts the cycle and displays E64 to ensure safety. This is fundamentally an electrical continuity failure within the 240V circuit. Most often, the heating element coil has snapped. However, the path also includes the high-limit thermostat and the thermal limiter (fuse). If these safety components trip—often due to restricted airflow in humid Pacific Northwest homes or clogged dryer vents—the circuit breaks, triggering the E64 alert. In rarer instances, a scorched wire terminal at the heater block or a failing heater relay on the control board is the culprit.
Likely Causes
- 1 Burned Heating ElementThe nickel-chromium coils inside the heater assembly can snap over time due to metal fatigue or overheating, physically breaking the electrical circuit.
- 2 Blown Thermal Limiter or High-Limit ThermostatIf the dryer overheats due to a clogged lint screen or restricted exhaust vent, these safety devices will trip or blow, opening the heater circuit to prevent a fire.
- 3 Damaged Wiring HarnessLoose connections at the heating element terminals can arc, burn out, and sever the connection back to the main control board.
- 4 Faulty Main Control BoardIf the heater relay on the main board fails in the open position, the board will read the circuit as open and trigger the E64 code.
How to clear / reset
You can attempt a temporary reset by disconnecting the dryer from power or flipping the dual-pole circuit breaker for 5 minutes. Once you restore power, try running a new cycle. Because E64 is a hard hardware fault indicating a genuine open circuit, the error will reappear the moment the control board tries to heat the unit and finds the same break. You must identify and replace the specific failed component—such as the heating element, thermostat, or fuse—using a multimeter to restore continuity and clear the code permanently.
Common replacement parts
When to call a pro
Reach out to a professional if you are uncomfortable working with 240V electrical systems or do not have a multimeter to verify continuity. Swapping out a heating element requires removing the dryer drum and bulkhead, which is a complex, labor-intensive task. Furthermore, if the element failed because of poor airflow, a technician can inspect your venting to prevent future fire risks. A-Fix Service offers a $90 diagnostic fee (waived upon repair approval) and provides a 1-year parts and labor warranty on all Frigidaire dryer repairs throughout Washington and Oregon.
FAQs
How much does it cost to fix an E64 code?
Depending on the root cause, a thermal fuse replacement runs $120-$160 including labor, while a full heating element assembly replacement typically costs $180-$280.
Can I fix the E64 error myself?
Yes, if you have a multimeter and know how to safely test for continuity on the heater and thermostats while the unit is completely unplugged from the 240V outlet.
Will the E64 code clear itself?
No. E64 is a hard fault indicating a physically broken electrical circuit. It will persist until the broken component is replaced and continuity is restored.
How long does it take to fix?
A professional technician can usually diagnose the open circuit in 15 minutes and replace the heating element or thermal fuse in about 45 to 60 minutes.
Is it dangerous to keep running the dryer with an E64 code?
The dryer's control board will lock out the heating cycle to prevent electrical shorts or fire hazards, so it will only tumble cold air or refuse to start entirely.
