Frigidaire Affinity Dryer E64 Error: Heating Element... | appliancefaults.com

Technical Background:

The E64 error code indicates that the dryer's electronic control unit (MCU) has detected an open circuit in the heating element circuit. The MCU monitors the voltage across the heating element relay. When the relay is energized, voltage should be present at the heating element. If the voltage is not detected, or if the current flow is too low (indicating an open circuit), the MCU triggers the E64 error and shuts down the heating circuit.

Symptoms:

The Frigidaire Affinity dryer displays an E64 error code and does not heat. The drum may still turn, but clothes remain wet after a drying cycle.

Possible Causes:

Blown thermal fuse on the heating element housing
Open heating element coil
Faulty wiring harness connection to the heating element
Defective heater relay on the control board
Blocked dryer vent causing overheating

Solution:

1

Disconnect power to the dryer at the breaker panel.
2

Remove the rear access panel using a 1/4-inch nut driver.
3

Locate the heating element housing.
4

Use a multimeter to test the thermal fuse for continuity. Replace if open.
5

Disconnect the wires to the heating element and test the element coil for continuity. Resistance should typically be between 9-15 ohms. Replace the element if open.
6

Inspect the wiring harness connections for damage or corrosion. Repair or replace as needed.
7

Check the dryer vent for obstructions and clean if necessary.

Safety Warning:

Disconnect power to the dryer at the breaker panel before performing any repairs. High voltage is present at the heating element and can cause serious injury or death. Follow Lock-Out/Tag-Out (LOTO) procedures.

Prevention:

Regularly clean the dryer vent and lint trap to prevent overheating. Inspect the heating element housing and wiring connections annually for signs of wear or damage.

Expert Tip:

To quickly test the heating element, bypass the thermal fuse (FOR TESTING PURPOSES ONLY!). If the dryer heats, replace the thermal fuse. NEVER operate the dryer long term with a bypassed thermal fuse.

Frequently Asked Questions

•What is the typical resistance range for a Frigidaire Affinity dryer heating element?

The typical resistance range for a Frigidaire Affinity dryer heating element is between 9-15 ohms.

•How do I test the heater relay on the control board?

Testing the heater relay requires a multimeter and knowledge of electrical circuits. Visually inspect the relay for burnt contacts. With power off, check for continuity across the relay coil. To test its function, carefully apply the rated voltage to the coil and check for continuity across the normally open contacts. If the relay does not switch or shows signs of damage, replace the control board.

•Where can I find a replacement thermal fuse for my Frigidaire Affinity dryer?

Replacement thermal fuses can be found at most appliance parts retailers, both online and in brick-and-mortar stores. Be sure to order the correct part number for your specific dryer model.
