This 40A model is a heavy-duty upgrade for lower amp units. Rule: Coil voltage must be exact; Amps can be higher, but never lower than your original one. **Q: My air conditioner runs on 220V/240V power. Why does this say "24V Coil"? Will it work?** A: Yes. The "24V" refers to the thermostat signal (Coil), not the main power, 240V is for the motor. This contactor is rated up to 600V, so it easily handles your 220V/240V AC unit. **Q: Does it matter which wire goes where on the coil? Is there polarity?** A: No. Since the coil operates on AC (Alternating Current), there is no polarity. You can connect the two low-voltage control wires to the side coil terminals in any order. **Q: Will this fit my [Carrier/Trane/Goodman] unit? The holes need to match.** A: Yes, in most cases. This contactor uses a universal mounting base. As long as your old unit is a 2-Pole contactor with a 24V Coil, this will fit and function correctly, regardless of the brand (Carrier, Trane, Goodman, etc.) **Q: My old contactor buzzes/hums — will replacing it fix that?** A: Often yes. Buzzing can be caused by a worn coil/armature, pitted contacts, or low control voltage. Replacing the contactor commonly resolves noise if the control voltage is stable and wiring is correct ## Frequently Bought Together - SunLee UL 2 Pole 40 Amp 50 RES Amp 24VAC Coil Contactor 45GG20AJ Replacement for Air Conditioner Condenser Compressor Heat Pump Refrigeration System - 24V 40VA Control Transformer， Primary 120, 208, 240V Secondary 24V Isolation Transformers，24V Transformer with Foot Mount for HVAC Furnace Multi Tap - BOJACK 1 Poles FLA 40 Amp Coil 24 VAC Air Conditioner Condenser Compressor Contactor AC Definite Purpose Contactor --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sg/products/368814078-sunlee-sunlee-45gg20aj-2-pole-40-amp-30-amp-24](https://www.desertcart.sg/products/368814078-sunlee-sunlee-45gg20aj-2-pole-40-amp-30-amp-24) --- *Product available on Desertcart Singapore* *Store origin: SG* *Last updated: 2026-11-01*
