Alde 3 kW PCB for Compact 3020 HE Boiler – Replacement Circuit Board

Alde 3 kW PCB for Compact 3020 HE Boiler – Replacement Circuit Board

The Alde 3 kW PCB for Compact 3020 HE Boiler (Part No. 3020-140 / 1040668) is a genuine replacement printed circuit board designed for the Alde Compact 3020 HE hydronic heating system used in caravans and motorhomes. It acts as the electronic control centre for the boiler’s 3 kW electric heating element and ignition system, managing power, ignition timing and overall system operation.

This PCB is essential when the original control board fails or malfunctions — without it, the electric heating element and ignition won’t operate properly. It includes the ignition transformer and necessary circuitry to support safe, efficient boiler operation.

How It Works

The PCB functions as the central electronic controller for your Alde boiler’s electric heating side:

1. Receives input signals from the control panel and thermostat.

2. Controls the 3 kW electric heating element, activating it when electric heat mode is selected.

3. Regulates ignition timing and safety checks to ensure safe element activation.

4. Monitors system status and helps relay error codes or fault conditions to the control panel (depending on boiler/software integration).

Because the PCB is sealed and specific to the Compact 3020 HE model, it must be replaced with the correct part if it fails — incorrect PCBs can cause malfunction or damage.

Who It’s For

• Caravan and motorhome owners with Alde Compact 3020 HE boilers

• Technicians and service engineers performing boiler repairs

• Anyone replacing a faulty or damaged PCB to restore electric heating function

Why Buy This PCB?

The printed circuit board (PCB) is one of the most important electronic components in your Alde boiler, acting much like a “brain” that oversees ignition and electric heating operations. A failing PCB can lead to no electric heat, error codes, or unreliable boiler behaviour, making replacement with a genuine Alde part critical for reliability and peace of mind.
