PF

Power Failure

Severity

Low

If your Whirlpool Dryer is displaying the error code PF, the control board has detected a fault identified as "Power Failure". Understanding the root cause helps you avoid an unnecessary service call.

Owner's Summary

PF simply means the dryer lost power during a cycle — usually due to a power outage or tripped breaker. This is not a malfunction. Press Start to resume your cycle. If PF happens regularly with no known outage, check the circuit breaker.

Symptoms

Whirlpool dryer display shows PF, stopped mid-cycle after power outage

Common Causes

Power outage or interruption during cycle
Tripped circuit breaker
Loose power cord connection
Voltage fluctuation from utility company

How to Fix

1 Press Start to resume the interrupted cycle
2 Check circuit breaker panel and reset any tripped breaker
3 Inspect power cord connection at the dryer terminal block
4 If PF occurs repeatedly without an outage, have an electrician check the circuit

Tools You'll Need

Screwdriver Set Flashlight

These are simple, low-risk fixes most homeowners can do with tools already in a basic toolbox.

Technical Explanation

The CCU stores active cycle state in volatile RAM. When AC supply drops below the operating threshold, the CCU detects the voltage drop and on power restoration displays PF to inform the user the cycle did not complete normally.

Is It Safe to Keep Using?

No risk. This is an informational code. Simply press Start.

Technician's Pro Tip

Electric dryers require a dedicated 240V 30A circuit. If PF occurs frequently without a known outage, check that the dryer isn't sharing its breaker with other high-draw appliances — this is both a code violation and a fire risk.
