Duratech DURAPRO R32 Relay

This genuine Duratech relay is a replacement electrical component for DURAPRO heat pump units running R32 refrigerant. Relays are essential switching devices that control the operation of various heat pump functions.

What Does a Relay Do?

A relay acts as an electrically operated switch, allowing a low-power signal from the control board to activate higher-power components such as the compressor, fan motor, or heating elements. When the control system calls for a particular function, the relay closes the circuit and allows current to flow to that component. This protects the sensitive control electronics from handling high currents directly.

Signs of Relay Failure

Relays can wear out over time due to the repeated electrical cycling they endure. Common symptoms of a failing relay include components not activating when they should, intermittent operation where functions work sometimes but not others, clicking sounds from the electrical panel without the corresponding component starting, or the heat pump failing to respond to commands altogether. If diagnostics point to a specific circuit not engaging, the relay on that circuit is a prime suspect.

R32 Compatibility

This relay is specified for DURAPRO units using R32 refrigerant. While relays may appear similar across different models, using the correct part ensures proper electrical ratings and fitment. Always confirm your unit’s refrigerant type before ordering.
