What MFD capacitor do I need for my ICP AC?

The correct replacement for ICP model RGS150HEAA0AGAA — 45+5 MFD 440V | Ships Today is this exact part. It is the factory-specified replacement with exact OEM specifications. Using a part with different specifications can cause equipment damage or void your warranty. You can verify this by checking the data plate on your ICP equipment which lists the model number RGS150HEAA0AGAA — 45+5 MFD 440V | Ships Today.

My AC hums but will not start. What part do I need?

An AC that hums but will not start is the classic symptom of a failed capacitor. The capacitor provides the electrical boost needed to start the compressor and fan motors. When it fails, you hear the hum of the motor trying to start but it cannot overcome inertia. Other symptoms include the fan spinning slowly, the AC cycling on and off rapidly, or a visibly swollen or leaking capacitor. Replacement cost: $15 to $80 for the part, DIY in 30 minutes.

Overview

This OEM dual run capacitor provides the steady phase-shifted boost that keeps both the compressor and the condenser fan motor running on your ICP RGS150HEAA0AGAA. Rated 45+5 MFD at 440V, it ships with the protective capacitor boot (OEM 1171842) and the oval mounting clamp (OEM 1171552) for a complete, secure installation. The capacitor is the single most common reason an outdoor unit hums but won't start: as the dielectric ages it loses capacitance, swells, or shorts, leaving the motors unable to develop starting torque. A weak capacitor also makes motors run hot and draw excess amperage, shortening their life.

Installation Guide

Safety First — Disconnect power and verify zero voltage with a multimeter, then discharge the capacitor across its terminals with an insulated resistor.
Access — Remove the condenser electrical-access panel.
Document — Photograph the HERM, FAN, and C terminal wiring before disconnecting.
Remove — Slip the wires off the terminals, loosen the oval clamp, and lift the old capacitor out.
Install — Mount the new capacitor in the clamp, fit the boot, and reconnect each lead to the matching terminal per your photo.
Test — Restore power and confirm both the compressor and fan start promptly with no hum.

Signs You Need a Replacement

Frequently Asked Questions

Does this Capacitor fit my ICP RGS150HEAA0AGAA — 45+5 MFD 440V | Ships Today?

Yes. This is the factory-specified OEM capacitor for the ICP RGS150HEAA0AGAA — 45+5 MFD 440V | Ships Today. It is a direct drop-in replacement that fits without modification. Always verify the model number on your equipment nameplate before ordering.

How do I replace the capacitor on my ICP RGS150HEAA0AGAA — 45+5 MFD 440V | Ships Today?

Difficulty: Easy (20–30 min)
Step 1: Turn off power at breaker. Step 2: Open condensing unit panel. Step 3: Photograph the old capacitor wiring (Common/Herm/Fan). Step 4: Discharge old capacitor with insulated screwdriver. Step 5: Disconnect and remove old capacitor. Step 6: Mount new capacitor, reconnect wires to matching terminals. Step 7: Close panel, restore power, test. Tools: screwdriver, needle-nose pliers.

My AC hums but won’t start. What part do I need?

An AC that hums but won’t start is the classic symptom of a failed capacitor. The capacitor provides the electrical boost to start the compressor. When it fails, you hear humming but the motor can’t overcome inertia. Other symptoms: fan spinning slowly, AC cycling on/off rapidly, or a visibly swollen capacitor. Fix: replace capacitor ($15–$80 DIY, 30 min).

Is this capacitor compatible with Bryant or Payne too?

Many ICP parts are cross-compatible with Bryant and Payne since all three brands are manufactured by Carrier Global Corporation. The same physical part is often used across brand labels with different model numbers. To verify: check your Bryant or Payne equipment service manual for cross-compatible part numbers, or email info@nationalhvacparts.com with your model number.

Should I use OEM or aftermarket for my ICP capacitor?

OEM strongly recommended. OEM capacitors have ±6% MFD tolerance vs aftermarket ±10%. The looser tolerance causes motor winding stress, higher temps, and shorter compressor life. Price difference is only $10–$20 — OEM is the clear value choice.

How fast does National HVAC Parts ship?

Orders placed before 3:00 PM CST ship the same business day. Standard delivery is 2–5 business days anywhere in the continental United States. Express shipping available at checkout. We ship from Houston, TX to all 50 states. 30-day return policy on all parts.
