Indoor unit displays H8 and system may run at reduced capacity

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

Indoor fan motor overheating, Blocked blower wheel, Incorrect fan speed setting in service mode, Failing motor bearings

Safety first: Turn off power before accessing the indoor fan.

Steps to try:

Clean blower and filters: Remove dust buildup that can overload the motor.
Check for obstructions: Ensure no wiring or insulation is rubbing against the blower wheel.
Test fan speeds: After cleaning, run the unit and cycle through fan speeds. If H8 appears at high speed only, the motor may be weak.

When to call a pro: Persistent H8 indicates the indoor fan motor or control board may need replacement.
