Kenmore Dryer Error Code E52

The E52 error code on a Kenmore dryer indicates a motor fault condition, meaning the control board has detected that the drive motor either failed to start or stopped unexpectedly during a cycle. The drive motor is the core mechanical component responsible for rotating the drum and, in most configurations, also driving the blower fan that moves heated air through the drum. When the control detects a motor that is not running as expected, it throws E52 and halts the cycle to prevent damage to the motor windings or connected components.

The most common triggers for E52 fall into four categories: motor overheating, mechanical overload from a heavy or tangled laundry load, insufficient L1 supply voltage reaching the motor circuit, and an electrically defective motor or damaged wiring harness. When the motor overheats, its built-in thermal protector trips and opens the circuit as a safety measure. This protector is a self-resetting device, but it can require up to 30 minutes of cool-down time before it closes again and allows the motor to run. A drum that does not spin freely by hand suggests a mechanical obstruction or a seized motor bearing, both of which place excessive current draw on the motor.

Diagnosing E52 starts with a physical check: remove all laundry from the drum and attempt to rotate the drum by hand. Resistance or binding points toward a mechanical issue rather than an electrical one. From there, L1 supply voltage at the terminal block should be confirmed to be within the correct range, since low voltage causes the motor to draw higher current and overheat. The motor wiring harness should be inspected for chafed insulation, loose connectors, or burnt terminals, all of which can interrupt the motor circuit and produce this fault.
