What MFD capacitor do I need for my ICP AC?

The correct replacement for ICP model RGS243HEBH0AGAA — 35+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 RGS243HEBH0AGAA — 35+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 (capacitor plate assembly, part 1183001) supplies the starting and running torque for both the compressor and the condenser fan motor on your ICP RGS243HEBH0AGAA packaged unit. The 35+5 MFD, 440V dual capacitor combines two capacitors in one can — the larger 35 MFD side serves the compressor and the 5 MFD side serves the fan motor. A weak or failed capacitor is the single most common cause of a no-cooling call: the outdoor fan won't spin, the compressor hums but won't start, or the unit trips on overload.

Specifications

Spec	Value
OEM Part Number	1183001
Type	Dual run capacitor
Brand	ICP (Heil / Tempstar / Comfortmaker)
Capacitance	35 + 5 MFD
Voltage Rating	440V (compatible with 370V applications)
Shape	Round
Terminals	HERM / FAN / C

Compatibility

Fits the ICP RGS243HEBH0AGAA and related RGS243-series packaged gas/electric units sold under Heil, Tempstar, Comfortmaker, and Arcoaire. Verify the printed MFD rating on your existing capacitor before ordering — a 440V cap safely replaces a 370V cap of the same MFD.

Installation Guide

Safety First — Disconnect power and verify zero voltage with a multimeter.
Access — Remove the condenser-section service panel.
Document — Photograph the HERM, FAN, and C terminal wiring before disconnecting.
Remove — Discharge the old capacitor across the terminals with an insulated screwdriver, then pull the leads and remove the mounting strap.
Install — Secure the new capacitor and reconnect each lead to its matching terminal per your photo.
Test — Restore power and confirm the fan and compressor start cleanly on a cooling call.

Signs You Need a Replacement

Condenser fan won't start or starts slowly
Compressor hums but won't run, then trips on overload
Bulging, leaking, or burst capacitor can
Measured capacitance is more than 6% below rating

Frequently Asked Questions

Does this Capacitor fit my ICP RGS243HEBH0AGAA — 35+5 MFD 440V | Ships Today?

Yes. This is the factory-specified OEM capacitor for the ICP RGS243HEBH0AGAA — 35+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 RGS243HEBH0AGAA — 35+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?
