Frigidaire Dryer AL-16 Error Code — What It Means
AL-16 does not appear in official Frigidaire or Electrolux dryer diagnostic code lists. The documented heat and control codes for Frigidaire dryers are E61 (control board relay fault), E63 (heating circuit ground fault), E64 (open heating circuit), and E66 (door/thermal safety). If your display shows AL-16, verify the exact model number and recheck the screen. It may be a misread of another code or a platform-specific variant not covered in standard service literature. Most heat-related faults on Frigidaire dryers trace to the heating element, thermal fuses, or the main control board relay.
Common Causes
- Failed heating element An open coil or grounded heating element is the most common cause of heat circuit codes on Frigidaire dryers.
- Blown thermal fuse or high-limit thermostat Safety cutoffs in the heater duct or on the blower housing open the circuit and trigger heat fault alarms.
- Control board relay stuck or open The main control uses relays to switch power to the heater, and relay failure produces E61 or similar heat codes.
- Damaged heater circuit wiring or connectors Burnt terminals, corroded connectors, or broken wires between the control and heater assembly cause open or intermittent faults.
- Heater circuit shorted to chassis ground If any heater wire or coil touches the dryer frame, the control reads a ground fault and shuts down.
Step-by-Step Fix
- Disconnect power at the breaker or cord and wait two minutes to discharge capacitors on the control board.
- Record the exact code from the display and locate the model and serial tag inside the door or on the frame to confirm your dryer platform.
- Remove the lower front panel or rear access panel to expose the heating element assembly and inspect the coil for breaks or areas touching the housing.
- Test the heating element for continuity with a multimeter and check for any short to ground by probing from each terminal to the dryer frame (you should see infinite resistance to ground).
- Check all thermal fuses and high-limit thermostats in the heater duct and on the blower housing for continuity, replacing any that read open.
- Inspect the wiring harness and connectors at the heater and control board for burn marks, corrosion, or loose pins, and repair or replace damaged sections.
- If all heater components test good, verify control board relay operation by listening for a click when the cycle starts, or substitute a known-good control board to isolate a relay fault.
Parts Often Needed
| Part | Notes |
|---|---|
| Heating element assembly | Amazon | Order by full model number to match coil wattage and housing for your dryer. |
| Thermal fuse kit | Amazon | Includes high-limit thermostat and thermal cutoff fuse, common safety devices that fail open. |
| Main control board | Amazon | Required if relay testing or substitution confirms a stuck or open relay on the board. |
| Heater wire harness | Amazon | Use if connectors are melted or wires are burnt between the control and heater terminals. |
When to Call a Pro
Call a technician if you cannot locate AL-16 in your owner’s manual and the display does not match any standard Frigidaire code, if you are uncomfortable working with 240-volt circuits, or if you have replaced the heating element and thermal fuses but the fault returns. A qualified service provider can cross-reference your exact model in the factory diagnostic database, use a tech-sheet flowchart to isolate relay and board faults, and access platform-specific wiring diagrams that are not published in consumer literature.
