Possible Causes

Blocked air filter, dirty evaporator or condenser coil, fan motor failure, high ambient temperature, refrigerant system issues causing high pressure

How to Fix / Troubleshooting

Safety: Disconnect power before cleaning or inspecting internal components.

Steps to reduce overload conditions:

  • Clean air filter: Remove and wash the filter with warm soapy water. Dry completely before reinstalling.
  • Clean coils: Access the indoor evaporator and outdoor condenser coils. Use a soft brush or vacuum to remove dust and lint. For heavy buildup, use a non-corrosive coil cleaner following the product instructions.
  • Check fans: Verify that both indoor and outdoor fans start and run smoothly when the unit is powered. If a fan does not run, the motor or capacitor may be faulty.
  • Improve ventilation: Ensure the unit has adequate clearance from walls, curtains, and other obstructions. Avoid operating in enclosed spaces without proper exhaust (for portable units).
  • Allow cool-down: After an overload trip, leave the unit off for 20–30 minutes to cool before restarting.

If E8 recurs after cleaning and ensuring proper airflow, the system may have a refrigerant or compressor problem. Contact a qualified technician for pressure and temperature diagnostics.
