• Corrosion or water ingress in the connector or case

🛠️ Service Notes

• This is the unit marked Kad, and 3819873 is the one marked Kamd - they carry different settings, so the marking is what decides the order
• Control unit 3819875 shares this exact 1.146 kg weight and the same KAD and KAMD families but carries no marking, so weight will not separate the two - order by part number
• Check the supply, earth and connector before condemning the unit
