Ask a Question
  • If the switch is faulty , what effect does it have on the operation of the stove ?? Does this switch have anything to do with how the stove operates on negative pressure ??

    The switch has to close the circuit for power to get to the feed motor. Pressure switches can fail in two ways, fail to make the circuit or fail to hold the pressure and lose the circuit. If the switch isn't closing the circuit this doesn't necessarily mean the switch is the problem. It may be doing its job of preventing the feed system from operating if poor airflow is detected.
