it maintains the precise electrical specifications required to prevent logic errors in the control board or intermittent power loss to the blower assembly

3 scfm flow capacity and a maximum inlet pressure of 30 psig

a stuck contact in the time delay relay is a common culprit

The normally open (N/O) pressure switch construction utilizes a high-sensitivity diaphragm to verify proper combustion air flow before allowing the ignition sequence to proceed

Honeywell SP3000-WR Probe 30067439-890 it maintains the precise electricalThe Honeywell SP3000 WR is a specialized water resistant temperature probe engineered for precision monitoring in high moisture HVACR environments. This 2 inch stainless steel thermistor probe features a 5 foot lead wire, providing the necessary reach and durability for immersion or surface mount applications where standard sensors fail due to moisture ingress. As the direct replacement for Honeywell 198212CA, the SP3000 WR maintains exact resistance
