Older Kellogg American B325UA with a Furnas 82DA15BHAU1A pressure switch.
Just restarted this machine after years of sitting unused in a heated garage.
The unloader valve on the side of the pressure is stuck in the open position when compressor is operating. Is this a replaceable part? Do I need to replace the whole switch? Does anyone have any parts list for either the compressor or the switch? Thanks, Jim
