Replacing the Discontinued ActronAir SS1P (SS9R8) Soft Starter

If you’ve gone to order an ActronAir SS1P single-phase soft starter — the part often called the SS9R8 or simply “the SS9” — and found it’s no longer available, you’re not alone. ActronAir has discontinued it, and the genuine replacement is the 2035-011K soft starter kit. This guide explains what changed, what’s in the replacement kit, and what the swap involves, so there are no surprises on site. It’s written for licensed technicians — soft-starter replacement is mains-voltage work and must be carried out by a qualified person.

What’s changed

ActronAir has officially discontinued the Actron Controls SS1P 1PH Soft Starter (model SS9R8) — the single-phase soft starter capable of supporting condensers up to 18kW. It has been replaced by the genuine 2035-011K single-phase soft starter kit. The key practical difference is that the new kit includes a separate mounting bracket, which is why fitting it to existing SRD/SRA models can require some modification depending on the electrical panel layout.

What’s in the genuine replacement kit (2035-011K)

The kit is a complete replacement package, not just the soft starter board. It contains:

  • The single-phase soft starter (part 2035-011)

  • A 200–260 µF start capacitor

  • A soft start mounting bracket and a capacitor bracket

  • PCB nylon stand-offs, mounting screws, and a capacitor cable connection

​​

ActronAir’s instructions also recommend replacing the compressor run capacitor at the same time — a sensible call, since a tired run capacitor can undo the benefit of a fresh soft starter.

What the replacement involves (overview — not a substitute for the official instructions)

At a high level, the job is: isolate and lock out the power, discharge and disconnect the existing soft starter and capacitors, fit the new soft starter (on its bracket, with the supplied stand-offs), replace the start capacitor (and ideally the run capacitor), re-wire to the supplied diagram, then pull-test, re-power, and test-run. On the older SS1P, the new bracket is drilled and mounted over the existing DIN-rail position, which is the step that adds time. The full step-by-step, wiring diagram, and the models the kit suits are in ActronAir’s official document (9590-3027) — always work from that on site.

A note on pricing your job

Because the new kit can require panel modification on older SRD/SRA units, allow for the additional installation time when you quote — alongside the cost of the kit itself. Factoring it in up front keeps the job profitable and the customer informed.

Reading the soft starter’s LED

The soft starter has an on-board LED that tells you what it’s doing. A few of the most useful indications:

  • Off — ready to start. On — compressor running.

  • On for 2–3 minutes at power-up — the random power-up delay (normal; the 3-minute start delay can’t be cancelled).

  • 1 blink — high running current trip. 2 blinks — low running current trip.

  • 3 blinks — locked start-capacitor fault (if it then starts, check for low refrigerant pressures).

  • 4 blinks — locked rotor.

  • 5 blinks — low mains voltage (clears when voltage is restored).

  • 6 blinks — external run-capacitor fault.

​

Five lock-outs in a row will lock the soft starter out — cycle the system’s mains power to reset it.
