Blueridge EHC1 error code

What it means

EHC1 is a refrigerant leak alarm from the indoor unit sensor. The XS2A manual says the outdoor compressor stops and the indoor fan starts when the refrigerant sensor detects leakage.

Urgency

Likely causes

1. Refrigerant leakage detected near an indoor unit
2. Leak at refrigerant piping or flare joints
3. Damaged or disturbed refrigerant line
4. Indoor refrigerant sensor alarm condition

Homeowner fix

Turn the system off from the remote or breaker if safe, open windows if you notice odor or irritation, and keep ignition sources away from the indoor unit area. Do not open panels.

When to call a pro

Call a licensed HVAC technician promptly. Tell them the Blueridge manual defines EHC1 as refrigerant sensor detects leakage.

Repair vs replace

Leak repair is usually attempted first. Replacement becomes more likely if a coil or inaccessible line is leaking on an older system.
