field technicians often trim these stainless steel probe rods to meet specific low-water cut-off elevations prescribed by the boiler manufacturer

but a multimeter test for microfarads (MFD) is the only way to confirm if it has drifted outside the +/- 5% tolerance

providing the necessary resistance to keep the motor stationary even under maximum load conditions

this part protects the furnace or air handler from internal corrosion and helps prevent the growth of biological contaminants that often cause "dirty sock" odors in residential and commercial ductwork
