What does the shop sell?

Spare parts for gas and oil burners and boilers: gas valves, nozzles, ignition electrodes and transformers, pressure switches, flame detectors, fuel pumps, servomotors and burner control boxes.

How large is the catalogue?

Over 100,000 part numbers from every major manufacturer, brought into one structure so that parts from different brands can be compared and replaced.

Can I find a part by its number?

Yes. The order number, the manufacturer model and any supplier code all lead to the same part, so a number from an old invoice or a nameplate is enough.

What if the part is discontinued?

The catalogue records what the manufacturer replaced it with, and which parts from other brands do the same job — together with the conditions that apply.

The company is based in London and ships across the United Kingdom, Europe and the rest of the world.

Is the shop open yet?

The catalogue is being assembled now. The shop opens as soon as it is ready.

Description

The Siemens LME41.071C2 control box is designed for forced-draft gas burners operating in 1- and 2-stage mode. It runs an intermittent cycle and monitors pressure switches and a flame detector. During startup it starts the fan for pre-purge, then manages ignition and fuel release. If no flame is verified within the safety time, the controller locks out and requires a manual reset. This control box supports a flame sensor.

Further details

Air Pressure Switch Verification	airflow confirmed by air pressure switch
Connection pattern requirement	base or plug pattern must be compatible with burner
Control Functions	supervises pre-purge, ignition, fuel admission, and flame proving
Driven Components	ignition transformer, fuel valve, and fan
Flame Detector	ionization flame sensor or QRA flame sensor (with AGQ3.1A27)
Heat Demand Input	receives heat demand signal to start fan
Interchangeability	not interchangeable across series within same brand
Replacement Guidance	verify against burner's original specifications for correct timing and detection method
Safety Feature	lockout with manual reset if flame not confirmed within safety time

Choosing and fitting

When selecting a replacement burner control of this type, verify the exact series and type designation, and confirm that the supply voltage, pre-purge time, safety time for flame proving, and flame detection method match the burner. The base or plug pattern of the control must be compatible. Controls are generally not interchangeable across series, even within the same brand; mismatched safety times create a safety hazard.
