HVAC Repair Error Codes — Meaning & Repair Cost (2026)

A fault code turns "it's broken" into a specific diagnosis — and a specific diagnosis has a knowable price. Pick your brand and code below: each page explains what the code means, what usually causes it, and prices the matching repair with the same Estimated, source-cited ranges as the rest of the guide. Reviewed July 2026.

Error codes are brand-specific by design — the same fault reads differently on a Whirlpool than on an LG — so each brand × code gets its own page. Codes are national: your location changes the price (use the calculator on any code page), never the meaning.

Codes by brand

How a code becomes a cost

Each code maps to the repair problem it signals, and that problem's national ranges come from the same named, dated sources as our problem pages — localized to your metro by the published formula. Codes with no single repair path (like a plain power-failure code) are explained without a price module — we never force a mapping.
