Replacing a Brivis wall controller doesn't have to mean guesswork. This guide walks through the NC-6, NC-7, Touch Wi-Fi Kit and GDH manual thermostat, showing how to identify what's already on your wall and match it to the right replacement. We'll also cover compatibility checks, wiring clues, and when a swap turns into a bigger upgrade conversation — so you order the right part the first time.

If you have narrowed a Brivis evaporative cooler fault down to the PCB or control module, the next step is confirming which specific module your unit uses. The 526 PCB add-on module, the 516 low voltage network module, and the TEK467 electronic control box are not interchangeable and each suits a different control architecture. This guide explains what each one does, how their fault symptoms differ, how to read the BSB part code to confirm compatibility, and which unit types each module suits.

When a Brivis evaporative cooler stops responding or runs incorrectly, the fault is almost always in the electronic control layer rather than the fan, pump, or pads. This guide covers the key replacement parts for Brivis evaporative coolers: the 526 PCB add-on module, the 516 low voltage network module, the TEK467 electronic control box, and the NC-6 Networker controller. Includes a component fault symptom table, guidance on BSB part codes, and how to identify the correct module for your unit.

When a Brivis gas heater stops working, most homeowners want to know what they can legally do themselves and what requires a professional. The answer is clearer than most expect. This guide covers exactly what is legal for any homeowner to do, including fault diagnosis, component testing, filter maintenance, and parts sourcing, what requires a licensed gas fitter under AS/NZS 5601, and the one situation where you should stop immediately and call for emergency help.

Brivis, Braemar, and Bonaire ducted gas heaters share a common engineering platform, which means a significant number of spare parts are interchangeable across all three brands. This guide covers exactly which components cross over, including the N-E6 control board, White Rodgers 24V gas valve, and pressure switches across all Pa ratings, what differs between brands such as heat exchangers and wiring looms, and the only reliable method for confirming compatibility before you order: matching by BS part code.

A Brivis heater that won't ignite is one of the most common call-outs at the start of winter — and most faults come down to five key components. This diagnostic guide walks through the full ignition sequence, then covers pilot burner and ignition assembly faults, thermocouple failure, thermistor errors, pressure switch lockout, and control board faults. Includes a fault symptom reference table and guidance on what homeowners can legally diagnose vs what requires a licensed gas fitter.

Ordering the wrong Brivis spare part almost always comes down to one thing — not having the correct part number before placing the order. This step-by-step guide shows you exactly how to find the data plate on your Brivis heater, read BS part codes, confirm gas type (NG vs LPG), identify the correct pressure switch Pa rating, match transformer amperage, and tell the difference between N-E6 control board variants. Get it right the first time.

When a Brivis ducted gas heater stops working, the fault usually comes down to one specific component. This complete guide covers every major spare part in the Brivis range — ignition assemblies, pressure switches, control boards, thermocouples, gas valves, and transformers — including how to identify the correct part by BS code, why gas type and Pa rating matter, and what to check before you order. Covers Brivis, Braemar, Bonaire, and Buffalo platform compatibility.

Buffalo ducted gas heaters run on the same engineering platform as Brivis, meaning a significant proportion of spare parts are directly compatible. This guide explains the relationship between the two brands, which parts cross over reliably (control boards, ignition assemblies, gas valves, pressure switches), and how to confirm compatibility for your specific Buffalo unit before ordering.

Choosing between the Brivis NC-6, NC-7, and Touch Wi-Fi Kit comes down to interface preference and remote access needs rather than basic compatibility, since all three run the same network platform. This side-by-side comparison covers interface type, app control, and which option suits a like-for-like replacement vs an upgrade vs a new install, plus the GDH thermostat for heat-only systems.

R32's higher operating pressures and A2L flammability classification mean manifold gauge compatibility is a genuine safety and compliance issue, not just a spec sheet detail. This guide covers how to verify pressure ratings, seal materials, and refrigerant compatibility on your existing manifold, plus what changes in the charging workflow when you move from R22 or R410A onto R32 systems.

Reading a manifold gauge correctly is a foundational skill that separates confident diagnosis from guesswork. This step-by-step guide covers gauge layout and scales, superheat and subcooling calculation, and how to interpret abnormal pressure readings to diagnose what's actually happening in the system.
