Unit frequently trips the household circuit breaker or blows fuses when starting or running.

Safety first: Repeated breaker trips indicate a potential fire hazard. Unplug the unit and do not reset the breaker repeatedly without finding the cause.

Steps:

• 1. Dedicated circuit: Ensure the Insignia AC is on a dedicated circuit with the correct amperage rating. Do not share the outlet with other high-draw devices.
• 2. Inspect cord and plug: Look for damage or overheating at the plug. Replace the power cord assembly if any defects are found.
• 3. Internal inspection: With the unit unplugged, check for obvious shorts: burned wires, melted insulation, or metal parts contacting live terminals.
• 4. Check capacitor and motors: A failed capacitor or motor can draw excessive current. Replace any visibly damaged capacitor and have motors tested by a technician.
• 5. Professional diagnosis: If no obvious cause is found, a technician should measure running current and insulation resistance to identify the faulty component.
