Can a WGen9500DFc Run a Refrigerator, Furnace and Sump Pump Together?

Use the SizeDial Generator Wattage Calculator
Short answer: using SizeDial’s built-in planning estimates, yes, with substantial wattage headroom. But you still need to verify the actual appliance labels, voltage, and safe household connection method.
The planning math
SizeDial currently estimates 192 running / 1,200 starting watts for a refrigerator-freezer, 875 / 2,350 for a furnace blower, and 800 / 1,300 for a sump pump.
Together they total 1,867 running watts. The largest extra startup demand is the furnace blower at 1,475 watts above its running load, producing a planning peak of about 3,342 watts.
How that compares with the WGen9500DFc
Westinghouse rates the generator at 9,500 running / 12,500 peak watts on gasoline and 8,500 / 11,200 on propane. The example load therefore fits comfortably inside either published fuel rating.
The important catch
“Enough watts” does not mean “plug everything in any way you want.” A furnace blower may be hardwired and a sump pump may be critical equipment. Verify the actual labels and use an appropriate transfer/connection method for circuits in the home.
