The defect
Thor Motor Coach (TMC) is recalling certain 2017 Quantum KM24 motorhomes. The power supply wire for the steps was incorrectly attached to a 50 amp circuit breaker instead of being connected to a 20 amp circuit breaker.
The risk
Should the step circuit be overloaded, the breaker may not trip as intended, increasing the risk of a fire.
