AGA is a premium British cooking brand known for cast‑iron ranges, radiant heat, and distinctive multi‑oven designs. In NYC homes, AGA units often serve as the centerpiece of the kitchen and see daily, high‑heat use. While the construction is robust, heavy thermal cycles, older installations, and ventilation constraints can introduce issues over time. This guide summarizes the most common AGA symptoms, provides error/alert patterns seen in modern control modules, and explains practical DIY checks vs. when to call a qualified technician. Our goals: speed up diagnosis, prevent unnecessary parts replacement, and extend service life. You’ll find frequent faults, 25+ fault indicators, technical notes (sensors, thermostats, relays), quick fixes, and decision points for repair vs. replacement.

Technical Details
AGA modern ranges couple traditional cast‑iron mass with electronic control: oven probe (NTC), high‑temp thermostat, solid‑state relays or contactors, convection/cooling fans, and ignition modules. Persistent high heat causes sensor drift and relay wear. Probe resistance typically measures ~1 kΩ–1.1 kΩ at 25 °C for some NTC families (check spec), increasing with temperature; out‑of‑range values trigger E01/E11/E18.Ignition systems require correct electrode gap and strong ground. Weak flame sense (E13) often traces to a dirty or cracked electrode. Fan monitoring may use tach feedback; stalled fans raise E07/E19 and drive over‑temp (E02). Control boards can develop hot‑spot solder fractures near power components. Door interlocks and locks must read closed for bake/broil cycles; self‑clean lock motors can fail (E16). Thermal fuses protect wiring paths and should test continuity when cool.
Quick Fixes
Uneven bake: verify rack placement; run calibration if available; inspect door gasket for gaps and replace if compressed.Slow preheat: confirm correct supply voltage and stable gas pressure; clear vents; power‑cycle to reset control logic.No ignition/clicking only: dry burners after spills; clean electrode and burner cap seating; check that burner caps are centered; try a controlled re‑seat of connectors with power off.Fan noise: remove debris, check for wobble; if seized, schedule bearing/motor replacement.Over‑temp alerts: ensure ventilation path is open; clean filters; avoid stacked pans blocking airflow.Preventive: periodic gasket inspection, gentle door handling, annual professional safety check for gas pressure/leaks, and cleaning around ignition components.
Repair vs Replace
Repair is typically favored: thermostats, probes, relays, fans, and igniters are replaceable at far lower cost than a new AGA range. Replacement makes sense only for severe structural damage (warped cavities), repeated board failures from environmental heat, or when a major upgrade is desired. Most performance issues respond well to calibrated repair.
