Tandoor Oven : How they work, common issues we fix

A tandoor oven is a high‑heat, cylindrical oven traditionally used to bake flatbreads like naan and to cook meats and other dishes with a distinctive smoky flavor. In restaurants, hotels, and even home kitchens around Nairobi, tandoor‑style cooking is prized for speed, flavor, and authenticity, which makes reliable operation and timely repairs extremely important. When a tandoor develops faults or heat‑loss issues, cooking quality drops fast and fuel costs can rise, so understanding how it works and what goes wrong is key.

How a tandoor oven works

Most tandoor ovens are cylindrical clay or metal chambers, open only at the top, with the heat source at the bottom. Fuel—wood, charcoal, or gas—burns at the base, heating the thick clay walls, which absorb and store thermal energy and then radiate it back into the chamber. This creates intense radiant heat (often close to 500 °C) combined with convection currents and smoke, which brown and cook food quickly while giving it a characteristic tandoori taste.

Foods such as naan are slapped directly onto the hot inner walls, where they cook largely by conduction, while meats and vegetables are skewered and hung vertically so that juices drip onto the embers, adding extra flavor. Electric tandoor models replace charcoal with heating elements and thermostats, but the principle remains the same: heat retention, high temperatures, and even cooking.

Common tandoor oven problems

Over time, intense heat, poor maintenance, and harsh weather can cause several issues that reduce performance or make the oven unsafe. These faults often present as uneven cooking, longer heat‑up times, flame instability, or visible cracks and damage. Professional inspection and repair can restore efficiency, safety, and flavor consistency.

The table below lists common tandoor oven problems along with typical repair solutions.

Common issue What happens How it is usually repaired
Uneven heating / hot spots Some areas cook faster; others stay raw. Clean ash and debris from walls; realign or replace burner/hob; rebuild damaged clay sections.
Cracks in clay chamber Heat escapes, fuel use rises, and oven cools faster. Patch small cracks with clay‑cement or fire‑clay paste; replace severely cracked sections.
Burner or gas supply problems Flame is weak, flickering, or fails to ignite. Unclog or replace gas jets; check and tighten gas lines; replace faulty igniter or thermostat.
Slow heat‑up or poor efficiency Oven takes longer to reach cooking temperature. Seal cracks; clean flue and ash; inspect and replace damaged insulation or clay lining.
Door or top‑opening issues Heat escapes through loose or broken lid/door. Re‑fit, seal, or replace the lid/door assembly so it closes tightly.
Electrical faults (electric models) Elements fail, thermostat gives wrong readings, or the oven won’t turn on. Replace broken heating elements or control boards; recalibrate or replace thermostat.

Why professional repair matters

Because a tandoor oven works at such high temperatures, improper repairs—such as using ordinary cement instead of refractory or fire‑clay material—can lead to further cracking or even sudden failure. Experienced technicians can inspect the clay lining, burner, insulation, and structural supports, then recommend cost‑effective repairs or targeted replacements that restore full performance. Regular servicing also helps prevent small faults from becoming major breakdowns, saving fuel and downtime.
