Expert Review
Is your milk fridge playing up? Maybe the display is flickering, or it's not holding temperature like it used to. It's often the main circuit board, the 'brain' of the unit, that's gone faulty. Swapping out the PCB is a surprisingly quick job for a qualified engineer, getting you back to serving perfect coffees in no time.
Installation & Maintenance
- Disconnect mains power before attempting any installation.
- Photograph wire connections before you remove the old board.
- Ensure all new connections are secure and tight.
- Keep the new PCB and surrounding area clean and dry.

Q: Is this a genuine Polar spare part?
A: Yes, this is an official Polar replacement part, SKU AK454, guaranteeing compatibility with the DB109 model.
Q: Can I install this myself?
A: We strongly recommend that any work on electrical components is carried out by a qualified commercial catering engineer for safety and compliance.
