or the 632200R pressure switch has failed

it maintains the integrity of the unit’s combustion sequence by verifying proper venting before ignition

its 425 psi range and 450 psi maximum bellows pressure make it suitable for many high-pressure AC applications

ensuring the unit operates within its designated thermal envelope without the risk of nuisance tripping or safety bypass associated with non-spec alternatives

This nickel-plated brass body is critical for balancing two-pipe heating systems

York 031-02203-000 Suppressor 321702-401 or the 632200R pressure switchThe York 031 02203 000 Suppressor is a critical industrial grade component designed to protect HVAC contactors and sensitive control logic from transient voltage spikes. Operating effectively at 208V 240V AC, this surge suppressor functions by clamping induction related voltage impulses that occur during the opening and closing of contactor coils. By mitigating these electrical "noise" spikes, the 031 02203 000 prevents arc over damage and premature
