Kenmore Washer Smells Like Burning Rubber: What's Wrong?
Updated 2026-08-14
A rubber-burning smell from a washer is worth taking seriously, but the cause is usually one of a few well-understood issues.
A new machine or new belt
If the washer is brand new or just had a belt replaced, a faint rubber smell for the first several cycles is normal as the belt breaks in — it should fade within a few loads.
A slipping or worn drive belt
On older machines, a worn or slipping belt is the most common cause — it can happen when the machine is overloaded, causing the belt to slip against the pulley and heat up.
Motor coupling wear
On some models, a worn motor coupling (a plastic part connecting the motor to the transmission, deliberately designed to be a wear item) can generate a burning smell as it fails.
Preventing premature belt wear
Avoid consistently overloading the washer, since an overloaded drum makes the belt work harder and slip more, generating heat. Redistributing an unbalanced load promptly, rather than letting the machine strain through repeated rebalancing attempts, also reduces belt and bearing wear over time.
When to stop using it
If the smell is strong, gets worse, or is accompanied by smoke, unusual noise, or the machine stopping mid-cycle, unplug it and don't run it again until it's been inspected.
Safety note: If a burning smell is strong, worsening, or paired with smoke or unusual noise, unplug the washer immediately and do not run it again until it has been inspected.
