Tumble Dryer Belt Broken or Snapped
A snapped drive belt is one of the most common tumble dryer faults and produces a very specific symptom: the motor runs (often audibly, sometimes louder than usual with nothing to drive) while the drum sits completely still.
Common causes
- Age-related wear and cracking, since rubber belts degrade over years of heat exposure
- A sudden overload, such as an especially heavy or bulky item straining the belt
- A seized idler pulley or drum bearing that put excess strain on the belt before it gave out
How to check it
- Unplug the dryer and remove the front or top panel per your model's layout.
- Look for the belt lying loose inside the cabinet rather than wrapped around the drum.
- Before fitting a new belt, always spin the idler pulley and drum by hand to rule out a seized component that caused the original failure.
Fixing it
Replacing a snapped belt is one of the more approachable dryer repairs. Note the belt's routing before removing any remnants — most models have a routing diagram on a sticker inside the cabinet, or the routing can be found from the manufacturer's manual. Fit the new belt around the drum, under the idler pulley (which keeps it tensioned), and onto the motor pulley, then rotate the drum by hand to confirm it's seated correctly before closing the cabinet.
When to call a technician
If the belt has snapped more than once in a short period, an underlying issue like a seized pulley or misaligned drum is likely straining it repeatedly, and that root cause should be diagnosed before fitting another belt.
Prevention tips
Avoid overloading the drum beyond the manufacturer's rated capacity, since this is one of the most common triggers for a sudden belt snap, particularly on older belts that have already lost some of their elasticity. If your dryer is more than seven or eight years old and has never had the belt replaced, consider it as preventive maintenance rather than waiting for it to fail mid-cycle.
Quick questions
How long should a drive belt typically last? Most belts last several years under normal use, though this varies with load size and frequency of use — a belt lasting seven to ten years isn't unusual in a moderately used household machine.
Can I use a universal belt instead of the manufacturer's exact part? It's best to match the exact length and rib pattern specified for your model, since a mismatched belt can slip, wear unevenly, or fail to seat properly on the pulleys.
Parts and repair notes
Drive belts are inexpensive and among the fastest parts to source for most major brands, making a snapped belt one of the more affordable and quickly resolved faults on this list. If a technician finds the idler pulley or motor pulley also needs attention while replacing the belt, addressing both in the same visit avoids a repeat call-out for a belt that would otherwise fail again soon.
Related issues to watch for
A snapped belt is sometimes the end result of a slipping belt that went unaddressed for too long, so if this is the second belt failure in a relatively short period, look closely at the idler pulley and drum rollers rather than assuming the new belt was simply defective.
