What MFD capacitor do I need for my ICP AC?

The correct replacement for ICP model RHS183S0CA0AAAA — 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 RHS183S0CA0AAAA — 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 (35+5 MFD, 440V) is the energy-storage component that gives the compressor and condenser fan motor the phase shift they need to start and run efficiently in your ICP RHS183S0CA0AAAA heat pump. It includes the OEM capacitor plate (1183001) and oval capacitor clamp (1171552) for a secure, vibration-free mount. A weak or failed capacitor is one of the most common causes of a no-cool/no-start call — symptoms include a humming compressor that won't start, a fan that needs a push to spin, frequent breaker trips, or a swollen, leaking can top.

Compatibility

Engineered as a direct OEM replacement for the ICP/Tempstar/Heil RHS183S0CA0AAAA heat pump condensing unit and other RHS-series models using the same dual run capacitor and oval mounting clamp. Verify the MFD and voltage rating stamped on your existing capacitor before installing.

Installation Guide

Safety First — Disconnect power at the disconnect and breaker, then verify zero voltage with a multimeter. Discharge the capacitor across its terminals with an insulated resistor before touching it.
Access — Remove the condenser service panel.
Document — Photograph all wire connections (HERM, FAN, C) before disconnecting.
Remove — Loosen the oval clamp, pull the spade connectors, and lift out the old capacitor.
Install — Mount the new capacitor with the included clamp, then reconnect each lead to its matching terminal per your photo.
Test — Restore power and confirm the compressor and condenser fan start cleanly.

Signs You Need a Replacement

Compressor hums but won't start, or the fan needs a manual spin
Bulging, leaking, or burst capacitor can
System trips the breaker on startup
Measured capacitance is outside the ±6% tolerance

Frequently Asked Questions

Does this Capacitor fit my ICP RHS183S0CA0AAAA — Ships Today?

Yes. This is the factory-specified OEM capacitor for the ICP RHS183S0CA0AAAA — 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 RHS183S0CA0AAAA — 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.
