# Duke 1302: Used-Buy Risk, Repairs & What to Check | KitchenRisk

> Used Duke 1302 buying guide, compartment thermostat risk, repair costs and what to inspect.

**Verdict:** inspect

Common drop-door Thermotainer holding cabinet with deep OEM parts support (thermostat ~$424, heating element strip ~$286); Duke's own troubleshooting table lists a defective thermostat or defective heating elements as the direct causes of a compartment not heating (or overheating), so verify every compartment reaches and holds temperature and that the pilot lights behave as described before buying used.

**Documented failure risks:**
- Compartment thermostat: OEM thermostat without knob (Duke TA-21, single-phase) lists at $424.00 on Parts Town. Duke's own troubleshooting table lists "Defective thermostat" and "Thermostat defective or requires recalibration" as direct causes of both "Compartment not heating" and "Compartment overheating," and gives a pilot-light diagnostic: "If amber pilot light is glowing, there is power up to the thermostat. If red pilot light is glowing, there is power after thermostat... If operative, replace thermostat."
- Heating element strip: OEM element strip (Duke TA-18A, 208V/1000W, Thermotainer Warmer) lists at $286.00 on Parts Town. Per Duke's troubleshooting table, "Defective heating elements" and a "Disconnected element terminal" are listed causes of a compartment not heating, with the correction "remove compartment and replace heating element located on each side of the bottom air space surrounding compartment."
