Arrived onsite to investigate a blower fan running continuously on a Bosch propane furnace that we installed yesterday. We contacted technical support, who explained that because this is a heat-only furnace, a dip switch needed to be changed to disable the refrigerant sensor function so the control board would allow the blower to shut off properly. We adjusted the dip switch accordingly and installed a new air filter as part of the installation. Verified proper operation; the system is working correctly at this time.
