Most Frequent Causes for Dryer tripping breaker

Cause 1The Circuit Breaker is Weak

Over time, circuit breakers can weaken. If the circuit breaker is weak, it may trip too often, even if the amperage draw is below the limit. If you have already checked all of the potentially defective dryer components, consider having an electrician replace the circuit breaker.

Cause 2Heating Element

Sometimes, if the heating element fails, it shorts out against the heater housing, causing the dryer to trip the circuit breaker. To determine if the heating element is at fault, use a multimeter to test each terminal for continuity to the case. If the heating element has continuity to the case, it is shorted out. If the heating element is shorted out, replace it.
