ABSTRACT:
An ice level sensor for a flake-ice icemaker of the type having an electrically grounded rotary shaft for scraping ice from a refrigerated surface into an underlying ice bin has a contact plate insulated connected to a control circuit, a metallic sensing arm suspended from and electrically connected to the shaft for sweeping a path in the ice bin, the sensing arm moving against the plate on contact with accumulated ice thereby completing an electrical circuit through the drive shaft and causing the control circuit to stop the icemaker.
