See full text

Systems and methods for electronics systems are provided herein. An electronics system may comprise a heating circuit and a fault detection system. The heating circuit may include a heating element. The fault detection system may include a first resistor comprising a first resistance, a second resistor comprising a second resistance, the first resistance being equal to the second resistance, a voltage level detector, and a controllable switch connected in series with the first resistor and the second resistor, the controllable switch in electronic communication with the voltage level detector. A fault may be detected in response to the first voltage being greater than the second voltage.
