AGA Cooktop Repair

The cooking surface on an AGA depends on the model. A traditional AGA has two large cast-iron hotplates, usually a hotter boiling plate and a cooler simmering plate, each covered by a heavy insulated lid when not in use. They draw heat from the same core as the ovens, so they are always warm. Conventional AGA range cookers have gas burners or induction zones that work like other modern cooktops.

On traditional hotplates, the most common complaint is slow recovery: the plate cools quickly when a pan is placed on it and takes a long time to heat back up. That usually means the core temperature is low, because of a thermostat, burner or element issue, or because the lids are often left open. Lid hinges wear and seals harden, letting heat escape. On conventional gas tops, igniters and spark modules fail, and burner caps must be seated correctly to light. Induction zones can stop working when a control board or coil fails, and power surges are a common cause.

On a traditional AGA, keep the lids closed and use flat-bottomed pans that make full contact with the hotplate. Check that the lid closes evenly and that the seal is intact. For gas tops, clean and dry burner caps and make sure they sit correctly. For induction zones, confirm that the pan is compatible and the control lock is off. If you smell gas, leave the house and call the gas utility or 911.

We check core temperature, thermostat, heat source, lid hinges and seals on traditional models. On conventional cooktops, we test ignition, burners, induction coils and controls.

Hotplate lid repairs and core heating repairs are usually worth doing on a traditional AGA. Conventional cooktop repairs also make sense on an expensive range cooker, though AGA-specific parts may take time to arrive. We explain the options.
