Why is my Whirlpool dryer not spinning?

A Whirlpool dryer that heats but doesn't spin almost always has a broken drum belt. The drum belt wraps around the drum and is driven by the motor pulley — when it snaps, the drum stops turning but the motor keeps running. You'll hear the motor humming but nothing moves. Drum belt replacement is a straightforward technician repair, $100–$180 total.

What does the PF error code mean on a Whirlpool dryer?

PF stands for Power Failure. The Whirlpool dryer detected that power was interrupted during a cycle — usually from a momentary power outage or voltage drop. The cycle has been paused. To resume, press Start/Pause. If PF appears frequently with no obvious power outages, check the dryer's power cord connections and the outlet voltage — an electric dryer needs 240V.

Why is my Whirlpool dryer taking too long to dry?

The most common cause is a blocked exhaust vent or a clogged lint filter. Reduced airflow means hot moist air can't escape, so clothes stay damp. A partially failed heating element — where some coils burn out but not all — also causes extended drying times. Clean the vent first; if clothes still take more than one cycle, have the heating element tested.

Most Common Whirlpool Dryer Problems & Fixes (2026)

Whirlpool is one of the most widely used dryer brands in Canada, and most Whirlpool dryer problems follow predictable patterns with well-known fixes. Whether your Whirlpool dryer is not heating, not spinning, squeaking on every cycle, or showing a PF or AF error code, this guide covers every major problem — cause, fix, repair cost, and when to stop troubleshooting and call a certified technician.

Problem 1: Not Heating

Dryer Runs But Produces No Heat

Cause: A blown thermal fuse is the most common culprit (usually from a blocked exhaust vent). A failed heating element, a tripped cycling thermostat, or a circuit breaker issue (electric dryers need both breaker legs on) can also cause no heat.

Fix: First, verify both breaker legs are on. Then test the thermal fuse with a multimeter — it's a small rectangular component in the exhaust duct path. If no continuity, it needs replacement. Always clean the exhaust vent when replacing a thermal fuse or it will blow again.

Call a tech if: The thermal fuse is intact but there's no heat. The heating element or thermostat needs professional diagnosis and replacement. Cost: $120–$220 for heating element.

Problem 2: Not Spinning

Drum Does Not Rotate

Cause: A broken drum belt is the most common cause. The drum belt wraps around the drum and drives rotation via the motor. When it snaps, the drum stops moving but the motor continues to run — you hear humming but nothing turns. Less commonly, a seized idler pulley or worn drum rollers can also stop rotation.

Fix: Open the dryer door and try to spin the drum by hand. If it spins completely freely with no resistance, the drum belt has broken. This is a moderate-complexity repair requiring the dryer cabinet to be opened. Cost with labour: $100–$180.

Call a tech if: The drum is hard to turn or won't turn at all by hand. Seized rollers or a locked motor require professional diagnosis.

Problem 3: Taking Too Long to Dry

Extended Drying Times / Multiple Cycles Needed

Cause: Clogged lint filter, blocked exhaust vent (the most common cause), a partially failed heating element (some coils burned out), or worn drum seals allowing heat to escape.

Fix: Start free: clean the lint filter, then go outside during a cycle and check exhaust airflow at the exterior vent — it should be strong and warm. If airflow is weak, clean the vent. If airflow is fine but clothes are still damp, the heating element needs testing.

Call a tech if: Airflow is clear but drying times remain excessive. A partial heating element failure needs a multimeter test to confirm. See our full guide on dryers taking too long.

Problem 4: Squeaking

Squeaking or Squealing During the Cycle

Cause: Worn drum glides (plastic or felt pads that support the front of the drum) or a failing idler pulley are the two most common causes of Whirlpool dryer squeaking. The squeak intensifies with heat and load weight.

Fix: Whirlpool sells drum glide kits specific to each model. The idler pulley is a simple swap once the cabinet is open. Many technicians replace the drum belt, idler pulley, and drum glides together since the labour to access them is the same for all three parts.

Call a tech if: The squeak is metal-on-metal (harsh grinding quality), which suggests rear drum bearing failure rather than glides. Rear bearing replacement is more complex and costs $150–$300.

Problem 5: PF Error Code (Power Failure)

PF Power Failure

Cause: Power was interrupted during a cycle — a brief outage, a voltage dip, or a loose power cord connection.

Fix: Press Start/Pause to resume the interrupted cycle. If PF appears frequently, check the dryer's 240V outlet and power cord connections at the terminal block inside the dryer (unplug first). A loose terminal connection causes intermittent voltage drops that trigger PF.

Call a tech if: PF appears repeatedly with confirmed stable power. The control board may be misreading voltage and needs replacement. Cost: $180–$320.

Problem 6: AF Code (Restricted Airflow)

AF Airflow Restricted

Cause: Whirlpool's newer dryers include a sensor that detects inadequate exhaust airflow. The AF code appears when the vent is blocked or significantly restricted.

Fix: Clean the lint filter immediately. Check the exhaust duct behind the dryer for kinks. Go outside and verify the exterior vent flap opens freely and airflow is strong. Use a dryer vent cleaning brush kit to clear the duct.

Call a tech if: The vent is clear but AF persists. The dryer's airflow sensor or control board may have failed. Also: AF that persists despite a clean vent sometimes indicates the dryer is not reaching operating temperature — a heating element issue.

AF code / vent issues	Vent cleaning / sensor	$80–$200
Rear bearing	Drum bearing	$150–$300

Frequently Asked Questions

A Whirlpool dryer that runs but doesn't heat has most likely blown a thermal fuse — a one-time safety device that triggers when the dryer overheats, usually from a blocked exhaust vent. Other causes include a failed heating element or a tripped circuit breaker. Check that both breaker legs are on (electric dryers need two legs), then test the thermal fuse.

A Whirlpool dryer that heats but doesn't spin almost always has a broken drum belt. When the belt snaps, the drum stops turning but the motor keeps running. You'll hear the motor humming but nothing moves. Drum belt replacement is a straightforward technician repair, $100–$180 total.

PF stands for Power Failure. The Whirlpool dryer detected that power was interrupted during a cycle. Press Start/Pause to resume. If PF appears frequently with no obvious power outages, check the dryer's power cord connections and the outlet voltage — an electric dryer needs 240V.

AF means Airflow Restricted. The dryer has detected that exhaust airflow is below the required threshold. Clean the lint filter immediately, then check the exhaust vent duct from behind the dryer to the exterior wall for blockages or kinks. Clear any blockages before continuing to use the dryer.

Whirlpool dryer squeaking is almost always worn drum glides or a failing idler pulley. The squeak gets louder as the dryer heats up and becomes constant once parts are badly worn. A technician can replace all wear parts at the same time since the labour overlap saves money. Cost: $120–$220.

The most common cause is a blocked exhaust vent or clogged lint filter. A partially failed heating element also causes extended drying times. Clean the vent first; if clothes still take more than one cycle, have the heating element tested. See our full guide on dryers taking too long to dry.
