About fixme.vip

When a furnace or air conditioner stops and the control board starts flashing a code, most homeowners have two questions: what does it mean, and is this something I can safely check myself or do I need a technician? fixme.vip answers both, one code at a time, for the major US brands.

What every guide includes

• What the code means, and where the meaning varies between models or control boards.
• Likely causes, ranked by probability.
• Safe checks a homeowner can do, limited to the thermostat, air filter, breaker, visible vents and condensate line.
• How a technician will diagnose the problem, so you can sanity-check a quote.
• Realistic US repair cost ranges.

How guides are made

We want you to know exactly how this content is produced.

• Each guide starts from the manufacturer's published meaning for that code, taken from control-board legends and installation manuals.
• The draft is written with the help of AI.
• Before it is published, a separate review step checks the draft against that meaning and against a safety checklist. A draft is rejected if it invents a code meaning, gives unsafe instructions such as bypassing a safety switch or working on gas or refrigerant, or quotes unrealistic prices.
• Pages about gas smells, carbon monoxide or flame rollout are also reviewed by a person before they go live.

Guides are signed "fixme.vip Editorial". None of them has yet been reviewed by a licensed HVAC technician, and we don't claim credentials we don't have. If you spot an error, please email us and we will fix it.

How the site is funded

The guides are free. The site earns money from affiliate links, for example as an Amazon Associate, and from connecting homeowners who ask for a repair quote with local professionals. Neither affects what a guide says. We never tell you to buy a part or call a professional when a safe free check is the right first step.
