What MFD capacitor do I need for my ICP AC?

The correct replacement for ICP model RHS036S0XB0AAAA — 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 RHS036S0XB0AAAA — 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 (part 1171552) is the start/run capacitor for the ICP / Tempstar / Heil RHS036S0XB0AAAA heat pump condensing unit. A dual run capacitor combines two capacitors in one oval can, delivering the phase shift that both the compressor and the condenser fan motor need to start and run efficiently. Rated at 35+5 MFD and 440 volts, it provides startup torque and smooth running current. A weak or failed run capacitor shows up as a compressor or fan that hums without spinning, a unit that short-cycles or trips the breaker, or a loss of cooling. Capacitors degrade with heat and age, making them one of the most frequently replaced parts in an outdoor unit.

Compatibility

Factory capacitor for the ICP RHS036S0XB0AAAA 3-ton heat pump and equivalent Tempstar, Heil, and Comfortmaker condensing units sharing the 1171552 OEM number. Always confirm the MFD and voltage rating on your existing capacitor's data label before installing.

Installation Guide

Safety First — Disconnect power at the outdoor disconnect and verify zero voltage with a multimeter. A charged capacitor stores a dangerous shock.
Access — Remove the condenser service panel to reach the electrical compartment.
Document — Photograph all capacitor leads (HERM, FAN, C/Common) before disconnecting.
Discharge & Remove — Safely discharge the old capacitor across its terminals with an insulated resistor, release the mounting strap, and remove it.
Install — Secure the new capacitor in the strap and reconnect each lead to the matching terminal per your photo.
Test — Restore power and verify the compressor and condenser fan start cleanly and the unit cools.

Signs You Need a Replacement

Compressor or condenser fan hums but won't start.
Capacitor top is bulged, swollen, or leaking.
Unit short-cycles or trips the breaker.
Reduced cooling output and higher energy use.

Frequently Asked Questions

Does this Capacitor fit my ICP RHS036S0XB0AAAA — 35+5 MFD 440V | Ships Today?

Yes. This is the factory-specified OEM capacitor for the ICP RHS036S0XB0AAAA — 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 RHS036S0XB0AAAA — 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?

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.
