Safety first: If breakers trip or you suspect a short, leave the unit unplugged until the fault is identified. Do not repeatedly reset breakers.

Inspect power cord and outlet: Ensure the cord is not damaged or pinched. Test the outlet with another appliance to confirm it is functioning correctly.
Check for moisture: Look for signs of leaks or condensation around the heater, motor, and control board. Resolve any leaks before further testing.
Visual wiring inspection: Remove rear and top panels. Inspect wiring harnesses for melted insulation, burn marks, or contact with sharp metal edges. Repair or replace damaged wiring.
Isolate components (advanced): A technician can disconnect the heater, motor, and pump one at a time to identify which component is causing the short. The faulty component must be replaced with a compatible NewAir part.
Professional service recommended: Because shorts and ground faults pose shock and fire risks, have a qualified technician perform detailed electrical diagnostics.
