Check Before Replacing

• Verify incoming line voltage at the inverter — low voltage can mimic inverter failure
• Confirm the main-board inverter command signal is present
• Inspect compressor windings, harnesses and connectors for damage or corrosion
• Check the ground connection and ground wire continuity
• Inspect thermistors, evaporator and condenser fans for related faults
• Assess sealed-system condition before condemning the inverter
