Why Is My Dryer Taking So Long? 7 Causes & Easy Fixes

A dryer that runs for 90 minutes and still leaves your clothes damp is more than an inconvenience — it’s usually a symptom of a specific mechanical or airflow problem that’s worth diagnosing properly. Homeowners across Ottawa searching for dryer repair near me often assume the worst, but the majority of slow-drying issues trace back to a handful of predictable causes. This guide walks through the seven most common culprits, what to check yourself, and when a component has genuinely failed and needs professional attention.

1. A Clogged Lint Trap or Exhaust Duct Is the Most Common Cause

Restricted airflow is behind the majority of slow-drying complaints, and it almost always starts with lint accumulation. The lint screen catches debris after every load, but over time lint migrates past it and builds up inside the exhaust duct — sometimes creating near-complete blockages several feet into the run.

To check this yourself:

• Clean the lint screen and feel for airflow at the exterior vent cap while the dryer runs
• Disconnect the duct from the back of the dryer and run a cycle — if drying time improves dramatically, the duct is the problem
• Inspect for kinked, crushed, or overly long flexible duct runs (over 25 feet equivalent is problematic)

In older Ottawa homes, especially in Kanata subdivisions built in the 1990s, dryer ducts frequently run through finished walls with multiple 90-degree elbows — each bend adds resistance and accelerates lint buildup. Rigid metal duct is always preferable to the flexible foil type.

2. A Worn or Broken Heating Element

Electric dryers rely on a resistance heating element to generate heat. When this element partially fails — one coil breaks while others remain intact — the dryer still runs and tumbles but produces noticeably less heat, extending cycle times significantly. A completely failed element means the drum blows only ambient air.

On Whirlpool and Maytag dryers (which share the same platform), heating element failures are common around the 8–12 year mark. GE GTD series machines and Samsung DV models are similarly prone. The element itself is a straightforward part to replace, but accessing it requires disassembling the rear or front panel depending on the model, and the thermal fuse and cycling thermostat should always be inspected at the same time — replacing just the element while ignoring a borderline thermostat often leads to a repeat failure within months.

3. A Failed Cycling Thermostat or Thermal Fuse

The cycling thermostat regulates the internal temperature by switching the heating element on and off throughout the cycle. When it fails in the open position, the element never heats; when it fails closed, it can cause overheating. A failed thermal fuse — a one-time safety device — completely disables heating until replaced.

LG dryers displaying error code d80, d90, or d95 are flagging airflow restriction percentages, which in turn stress the thermal limiter. Bosch heat pump dryers (the Serie 8 condensation line in particular) have a different failure mode: clogged condenser fins that cause the heat pump compressor to cycle inefficiently, which reads to the user as extended drying times rather than a clear error code.

4. Dryer Repair Near Me: When a Faulty Gas Valve or Igniter Is the Issue

Gas dryers present their own failure pattern. The igniter glows to light the burner, but a weak igniter that still glows without reaching ignition temperature will cause the dryer to run without producing adequate heat. Gas valve coils (the solenoid coils that open the valve) are another frequent failure — when one of two or three coils fails, the burner lights briefly then shuts off, cycling poorly throughout the entire load.

This is a very common failure on Whirlpool, Maytag, Roper, and Kenmore gas dryers. The symptom is clothes that are warm but never fully dry after a standard cycle. Replacing the valve coil kit is inexpensive but requires confirming gas supply, burner operation, and proper combustion — work that warrants a licensed technician.

If you’re in the Ottawa area and dealing with a gas dryer that heats intermittently, professional dryer repair from a licensed technician is the appropriate path — both for accuracy and safety.

5. Moisture Sensor Bars That Need Cleaning

Modern dryers use two metal sensor bars inside the drum to detect remaining moisture in the load. When these bars become coated with dryer sheet residue or mineral deposits, they misread the moisture level and signal the control board that clothes are dry before they actually are — or trigger the auto-dry cycle to end prematurely.

Cleaning the sensor bars with a small amount of rubbing alcohol on a cloth takes under five minutes and can restore accurate auto-dry performance immediately. Samsung, LG, and Electrolux dryers are particularly sensitive to sensor contamination because their auto-dry algorithms weight sensor data heavily versus timed drying logic.

6. An Overloaded Drum or Incorrect Cycle Selection

Oversized loads prevent proper tumbling, trapping moisture inside the mass of fabric. A dryer drum should be no more than three-quarters full to allow adequate air circulation. Similarly, selecting a low-heat or delicate cycle for heavy cotton or denim will extend drying time far beyond what most users expect — this is intended behaviour, not a malfunction.

7. A Worn Drum Seal or Felt Strip

The felt seal around the front or rear of the drum maintains the airflow pathway through the load. When this seal wears out, air bypasses the drum and exhausts around it rather than through the tumbling clothes — reducing effective drying dramatically. This is a commonly overlooked failure point on dryers over 10 years old. Technicians servicing units in areas like Kanata and surrounding Ottawa neighbourhoods frequently find drum seals that have been deteriorating for years without the homeowner connecting it to longer drying times.

Frequently Asked Questions

How do I know if my dryer’s heating element is bad versus a thermostat issue?

Both produce similar symptoms — low or no heat — but can be distinguished with a multimeter. A failed heating element shows no continuity across its terminals. A failed cycling thermostat or thermal fuse also shows no continuity but is a much smaller, less expensive component. Because these parts work together, a technician will typically test all three before recommending which to replace.

Is it worth repairing a dryer that’s 10 years old?

Generally yes, provided the repair cost is under 50–60% of the replacement value. Most dryer repairs — a heating element, thermostat kit, or drum seal — fall well within that threshold. Premium brands like Miele and Bosch are designed for longer service lives and are almost always worth repairing. Budget-tier machines approaching 12–15 years with multiple failing components are the exception where replacement makes more financial sense.

Can a clogged dryer duct be a fire hazard?

Yes — lint is highly combustible, and a severely restricted duct forces the dryer to run hotter than its design temperature. The National Fire Protection Association lists dryer duct maintenance as a leading cause of residential appliance fires. Cleaning the full duct run, not just the lint screen, annually is the standard recommendation — particularly for longer or more complex duct routes common in two-storey Ottawa homes.
