Observe. Check. Know when to stop.

We identify hazards before suggesting a check. Live power, gas, refrigerant, moving parts, unsafe access and other hazardous work are not tasks authorized by a guide. We separate user-accessible maintenance from work for an appropriate qualified professional.

We begin with the behavior a reader can see, hear or confirm through normal controls. A model number, error message and timing help define the question. We do not diagnose a failed component from a single symptom.

Manufacturer documentation, official support material, public agency guidance and other original sources establish the scope. We check that each material claim fits the documented model and procedure. If a claim is unsupported, we omit it or explain the uncertainty.

Explanatory illustrations are distinguished from product photographs. Credits identify generated images, and we retain source and permission records. No illustration is presented as a photograph of a product we tested.

Research is supported by its sources. Hands-on findings appear only where the experience is documented; we do not invent repairs or service history.

Paid placements carry a label. If a link can earn HouseTuned an affiliate commission, an accompanying disclosure explains that relationship. Commercial interests do not justify an unsupported claim.

Reported errors are checked against the article and original sources. Material mistakes are corrected, with significant changes explained on the page.
