What LE means on a Cooper & Hunter
The compressor stopped turning while it was supposed to be running.
On this platform, LE is a protection: the system stopped or throttled itself to prevent damage; many clear on their own once conditions return to normal.
Common causes
- A seized or failing compressor.
- A failed inverter drive.
- Liquid refrigerant flooding.
- Supply voltage collapsing under load.
How to fix it yourself
Do the reset and the visual checks, but the underlying repair needs a technician with a meter and the service manual.
- 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.
- If you own a multimeter and are comfortable using it, measure the supply voltage at the outdoor unit's L1 and L2 terminals with the unit running. A 230 V system should read roughly 208 to 253 VAC.
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
Technician diagnosis of the compressor and drive.
Which Cooper & Hunter units show LE
This page applies to Cooper & Hunter Sophia, Astoria, Olivia, Dakota, Hyper Heat, Alice and MIA units. Cooper & Hunter's own documentation lists LE as "Compressor stall (locked rotor)", 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 Cooper & Hunter shows this code
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 Cooper & Hunter LE code myself?
Yes. Turn the system off at the breaker for five minutes, then restart it. If LE comes back, the fault is real and needs the checks above.
Is it safe to keep running a Cooper & Hunter showing LE?
Not repeatedly. A protection code means the unit stopped itself to prevent damage, and resetting it over and over can turn a cheap repair into a compressor failure. Reset once, check the basics, and stop if it returns.
What will a technician check for LE?
Technician diagnosis of the compressor and drive. Ask for the measurements, not just a parts quote.
