Sime Electrical Short / Overcurrent

Furnace frequently trips the household circuit breaker or blows fuses.

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Shorted fan motor, Shorted pump motor, Damaged wiring harness, Faulty control board

Safety first: Do not repeatedly reset a breaker that trips immediately; risk of fire.

Visual inspection: With power off, inspect internal wiring for melted insulation, loose wires, or signs of arcing.
Isolate components (technician): A professional can disconnect fan, pump, and other loads one by one to identify the faulty component.
Replace defective part: Once identified, replace the shorted motor or board with a genuine Sime component.
