Admiral Dryer Error Code PF: Power Failure Troubleshootin... | appliancefaults.com

Technical Background:

The PF error code indicates a power failure was detected by the dryer's main control board (MCU). The MCU monitors the incoming voltage. If the voltage drops below a certain threshold or is interrupted, the PF error is triggered. This is stored in memory and may require a reset. The MCU logic needs a stable 120V AC path to operate correctly. Interruption on either L1 or Neutral will cause this fault.

Symptoms:

The Admiral dryer displays error code PF. The dryer may not start, or it may stop mid-cycle. The control panel might be unresponsive.

Possible Causes:

Intermittent power supply from the wall outlet.
Loose wiring connections within the dryer.
Faulty main control board (MCU).
Defective door switch.
Tripped breaker at the breaker panel.
Power surge or brownout condition.

Solution:

1

Unplug the dryer from the wall outlet.
2

Check the breaker at the breaker panel. Reset if tripped.
3

Verify the wall outlet is supplying 120V AC using a multimeter.
4

Inspect the dryer's power cord for damage. Replace if necessary.
5

Access the dryer's control panel and check wiring connections to the MCU. Tighten any loose connections. Use a 1/4-inch nut driver.
6

Test the door switch for continuity using a multimeter. Replace if faulty.
7

If all other components check out, replace the main control board (MCU).

Safety Warning:

Disconnect power to the dryer before performing any repairs. Lock Out/Tag Out (LOTO) procedures should be followed. High voltage is present when the dryer is connected to power.

Prevention:

Regularly inspect the dryer's power cord and wall outlet for damage. Avoid overloading the circuit by running other high-amp appliances on the same circuit. Consider using a surge protector.

Expert Tip:

To clear the PF error code on some Admiral models, simultaneously press and hold the Start/Pause and Cycle Signal buttons for 3 seconds. This may enter a diagnostic mode where you can clear error codes. Note: this may vary based on the actual model.

Frequently Asked Questions

•How do I access the main control board?

Typically, you'll need to disconnect power, then remove the rear access panel or the top control panel. Refer to the service manual for your specific model for detailed instructions and diagrams.

•What voltage should I expect to see at the dryer's terminal block?

You should see 240V AC between L1 and L2, and 120V AC from L1 to Neutral and L2 to Neutral. Use a multimeter to verify these voltages.

•Where can I find a replacement main control board for my Admiral dryer?

You can typically find replacement parts at appliance parts retailers online or at local appliance repair shops. Have the dryer's model number handy when ordering.
