Unit frequently trips the household circuit breaker when starting.

Safety warning: Repeated breaker tripping indicates a potentially dangerous fault. Do not repeatedly reset the breaker without investigation.

Steps:

• Inspect cord and plug: Unplug the unit and check for burn marks or damage. Replace the Argo power cord set if defective.
• Try different circuit: Plug the unit into a dedicated circuit with correct amperage to rule out overload from other appliances.
• Resistance checks: With the unit unplugged, measure resistance of the compressor and fan motor windings. Very low resistance or continuity to ground indicates a shorted component.
• Component replacement: Replace the Argo compressor or Argo indoor fan motor if they test shorted. If both test normal, the main PCB may be shorted and should be replaced.
• Professional service: If you are not comfortable with electrical testing, contact an authorized Argo technician.
