My ActronAir only cools (or only heats) — is it the reversing valve?

It can be — a stuck reversing valve, or a failed solenoid coil on it, is a classic cause of a system stuck in one mode. A technician can confirm whether it’s the coil (cheaper) or the valve body.

Do I need the coil or the whole valve?

Often only the solenoid coil has failed, which is the cheaper fix; sometimes the valve body has stuck or leaked and needs replacing. We’ll confirm which you need before you order so you don’t buy the wrong one.

Are valves the same for R22 and R410A?

No — reversing valves and their coils are refrigerant-specific. Always match to your system’s refrigerant; send us your model and we’ll confirm.

Genuine ActronAir Valves & Solenoid Coils | Guide

Genuine ActronAir reversing valve and solenoid coil — Actron Spare Parts.

Valves control where the refrigerant goes and how much of it flows — and on a reverse-cycle system they’re what lets one machine both heat and cool. When a valve sticks or its coil fails, you can get a system stuck in one mode, poor performance, or odd behaviour. This guide explains the main valves ActronAir uses, the important difference between a valve and its coil, and how to get the right genuine part.

The Valves & Coils ActronAir Uses

Reversing valve — switches the system between heating and cooling. A stuck reversing valve is a classic cause of a system that will only cool, or only heat.
Solenoid coils — the electrical coil that sits on a valve and drives it. Often it’s the coil that fails, not the valve body — an important and cheaper distinction.
Expansion / digital control valves — meter refrigerant flow precisely for efficient operation.
Service / access valves — the gas and liquid valves a technician uses to service the refrigerant circuit.

Coil or Valve Body? It Matters

A common point of confusion: the solenoid coil and the valve body are separate parts. Sometimes only the coil has failed (it’s burned out electrically) and a new coil fixes it; sometimes the valve itself has stuck or leaked and the body needs replacing — which, because it’s in the sealed circuit, is a bigger job. Getting this right saves money and time, which is why we always confirm which you actually need before you order.

ActronAir Valves & Coils FAQs

Getting the Right Genuine Valve or Coil

Valves and coils are matched to your refrigerant (R22 vs R410A), system, and — for coils — the voltage and the valve they fit. Valve-body work opens the sealed circuit and is ARC-licensed. Tell us your model number and whether you’re after the coil or the valve (or send a photo), and we’ll confirm the right genuine part. Call 1300 904 554 or email actron@nationalacparts.com.au.
