Honeywell Burner control (flame safeguard) DKO976-N mod.05 0416005U

Honeywell DKO976-N mod.05 0416005U is a burner control (flame safeguard) for gas or oil burners. It operates at 220–240 V, weighs 190 g including base, has protection class IP40, and is certified to EN 230. It can be installed in any position. This control manages ignition and safety sequences, including pre-purge, fuel valve opening, ignition transformer activation, flame monitoring, and lockout if flame is not proven within safety time.

Parts of this type are selected by exact series and type designation, supply voltage, safety and pre-purge times, and flame detection method (ionisation for gas, UV/IR for oil). The base or plug pattern must match the burner wiring. Verify the original part number and specification against burner documentation before ordering.

Items of this kind may fail to initiate ignition, lock out without flame signal, or cycle intermittently. Check for loose connections, damaged flame sensor, or incorrect supply voltage. If the control locks out, reset and observe sequence to identify fault stage.
