Possible Causes

Failed block heater element, Tripped GFCI outlet feeding heater, Unplugged heater cord, Open heater thermostat

Safety first: Block heaters are 120/240 VAC devices. Disconnect power before inspection.

Check power source: Verify the receptacle feeding the block heater has power and that any GFCI has not tripped.
Inspect cord: Ensure the heater cord is plugged in securely at both ends and not damaged.
Measure resistance: With power off, measure resistance across the heater leads. An open circuit indicates a failed element.
Replace heater: Replace the block heater with the correct Winco-specified part if failed.
