Combi boiler malfunctions are frequently observed, especially after the warranty period has expired. In particular, the failure known as “motherboard burnout” can render this device, which dominates extensive heating systems, completely inoperable. Before discussing the causes of motherboard burnout and how to prevent it, it is useful to explain exactly what it is and what function it serves.

Why Does a Combi Boiler Motherboard Burn Out?

The heat levels and electronic settings of a combi boiler are regulated by the mainboard, also known as the combi card. We can say that this part is, in a sense, the brain of the device. Like all other electronic cards, it malfunctions or “explodes” due to overvoltage, commonly known as voltage fluctuations. This is exactly the technical explanation for the malfunction known colloquially as combi boiler motherboard burnout.

How to Prevent Combi Boiler Motherboard Burnout?

The combi boiler is the device that ensures all gas and heating circulation in the house. Therefore, burnouts occurring in the mainboard, called the combi card, can lead to serious problems. On the other hand, the repair of these boards can take up to 30 days, and some companies do not cover board replacement under warranty. To prevent this issue, it is beneficial to use regulators that reduce voltage tension and prevent overloading. However, our customers frequently state that the regulators provided by boiler services are not functional enough.

The primary function of a regulator is to maintain a stable energy level and prevent fluctuations below or above a certain point. The biggest handicap of the regulators provided by boiler services is that they themselves can break down by being affected by overvoltage.

Prevent Combi Boiler Burnout with Trimbox

To protect your regulator and boiler against voltage fluctuations, you can benefit from the combi card protection systems developed by Trimbox. Trimbox is a system designed to protect the regulator as well. While it does not function as a traditional regulator itself, it ensures that voltage fluctuations in the devices reach stable and safe levels.

Simple precautions sometimes save lives. The best investment we can make for our family, our business, and our environment is protective measures. With Trimbox and GNDSeries, you can be protected from electricity-related damages and subsequent electrical fires.
