What H6 means on a KeepRite
The indoor board is not seeing the blower motor's speed feedback: the motor is stalled, failed, or unplugged.
On this platform, H6 is a fault: something has failed or is disconnected and needs diagnosis.
Common causes
- Debris jamming the blower wheel.
- A failed DC fan motor.
- A loose motor connector or damaged feedback wire.
- A failed fan drive on the board.
How to fix it yourself
Work through the checks below first; they resolve most cases. If they do not, the repair itself may need a technician.
- Reset the system: switch the breaker (or the outdoor disconnect) off, wait a full five minutes so the boards fully discharge, then switch it back on and restart from the remote.
- With power off, remove the filters and spin the blower wheel by hand; it should turn freely.
- Reseat the fan motor plug on the indoor board.
- Restart and listen for a hum without rotation.
Switch off power at the breaker before opening either unit. Capacitors in the outdoor unit hold a charge for several minutes after power is cut.
When to call a technician
A fan motor is a moderate DIY swap; if it spins freely and the plug is tight, the board is the suspect.
Which KeepRite units show H6
This page applies to KeepRite DLCSRA / DLCSRB / DLCLRA outdoor with DLFSHA / DLFSFA indoor (2015 and later) and DLC4 / DLF4 (2013 to 2015) units on the DLC4 / DLF4 series, 2013 to 2015 (Gree-built). KeepRite's own documentation lists H6 as "Indoor fan motor not running (no feedback)", the same definition used across the Gree platform it is built on. If your unit shows a code with a different shape (for example a four-character code, or a plain number), it is from a different table; use the lookup with your exact code.
Where KeepRite shows this code
DLC4 / DLF4 series, 2013 to 2015 (Gree-built): The code shows on the indoor unit's display in place of the temperature. If the display is off, press the Light button on the remote. Some models also count out the code as indicator blinks. E codes are system protections and faults, F codes are mostly sensor faults, H codes are outdoor and compressor protections, U codes are motor and valve faults, and P codes are power-supply faults.

Questions people ask
Can I reset a KeepRite H6 code myself?
Yes. Turn the system off at the breaker for five minutes, then restart it. If H6 comes back, the fault is real and needs the checks above.
Is it safe to keep running a KeepRite showing H6?
The unit will usually refuse to run, or run with reduced output, until the fault is cleared. Repeated resets do not fix anything and can mask a problem that is getting worse.
Do I need a technician for KeepRite H6?
Work through the checks below first; they resolve most cases. If they do not, the repair itself may need a technician. A fan motor is a moderate DIY swap; if it spins freely and the plug is tight, the board is the suspect.
